libtool/ChangeLog.1999
Gary V. Vaughan 9bf1ccc71a Simplify license variations, and add missing license texts. 
* ChangeLog, ChangeLog.1996, ChangeLog.1997, ChangeLog.1998,
ChangeLog.1999, ChangeLog.2000, ChangeLog.2001, ChangeLog.2002,
ChangeLog.2003, ChangeLog.2004, ChangeLog.2005, ChangeLog.2006,
ChangeLog.2007, ChangeLog.2008, ChangeLog.2009, NEWS: Add
all-permissive license.
* HACKING, README, README.alpha, TODO: Relax license to RMS
encouraged all-permissive terms.
* libltdl/README: Ditto. I added the original license text in
2007, and there's no need for it to be so long for such a trivial
file.
* libltdl/config/getopt.m4sh, libltdl/general.m4sh: Cvs-utils is
dead, and I am the author of these files, so consolidated license
terms to match regular Libtool licensing.
* HACKING (Licensing Rules): Update wording, and list of files for
the all permissive license.
(GPL with CVS-Utils exception clause): Removed.  No files have these
license any more.
(GPL with Libtool exception clause): Ditto, only libltdl/README
used to be distributed with this variation.
* AUTHORS: Add GPL license text.

Raw Blame History

1999-12-18 Alexandre Oliva <oliva@lsd.ic.unicamp.br>
* ltmain.in: Oops, `largarg' -> `lastarg'.
* ltmain.in (-Wc, -Xcompiler): Implemented in compile mode.
* ltmain.in (-Xcompiler, -Xlinker): Add to compile_command and
finalize_command.
(-Wc, -Wl): Likewise.
* tests/quote.test: Adjust quoting style of -Wl.
* ltmain.in: Oops, `echo' -> `$echo'.
* ltmain.in (-Wl, -Wc): Make commas argument separators, just like
in gcc.
* ltmain.in (libtool_args): Get all arguments properly enclosed in
quotes and backslash-protected when needed.
1999-12-16 Alexandre Oliva <oliva@lsd.ic.unicamp.br>
* ltdl.m4: Renamed from...
* libltdl/ltdl.m4: that no longer exists.
* configure.in (ACINCLUDE_M4_LIST): Removed libltdl/acinclude.m4.
* Makefile.am (aclocal_macros): Added ltdl.m4.
(libltdl/acinclude.m4): Concatenate libtool.m4 and ltdl.m4.
* bootstrap: Likewise.
* libltdl/Makefile.am (ACLOCAL): Remove the definition. Relying
upon -I may lead to duplicates.
* doc/libtool.texi: Suggest appending ltdl.m4 to acinclude.m4.
* libtoolize.in: Check AC_LIB_LTDL version number in aclocal.m4.
* libltdl/configure.in (with_auxdir): Do not use it as the
argument of AC_CONFIG_AUX_DIR, automake requires a literal here.
Use AC_CONFIG_AUX_DIRS/DIR_DEFAULT instead.
* libltdl/Makefile.am (ACLOCAL): Define with `-I .', as in
bootstrap.
1999-12-15 Thomas Tanner <tanner@ffii.org>
* libltdl/configure.in: path to auxiliary files can be specified
using --with-auxdir (idea by Howard Chu <hyc@highlandsun.com>)
* ltmain.in: don't remove multiple occurences from dependency_libs
of a library, otherwise many dependencies would get lost
* bootstrap: use "aclocal -I ." instead of adding the contents
of ltdl.m4 to acinclude.m4
1999-12-13 Gary V. Vaughan <gary@gnu.org>
* NEWS: updated.
* libltdl/Makefile.am: Use -no-undefined for dll compliance.
* libltdl/configure.in: Use AC_LIBTOOL_WIN32_DLL for dll
compliance.
* libltdl/ltdl.c: Define and use LTDL_GLOBAL_DATA to correctly
export global data symbols from libltdl.dll.
* libltdl/ltdl.h: Define and use LTDL_SCOPE to declare data
symbols as dllexport, dllimport or plain ornary extern depending
in the context in which it is used.
* doc/libtool.texi (Distributing libltdl): document use of
ltdl.m4.
* libltdl/configure.in: Removed header checks, as they are
automatically performed by AC_LIB_LTDL.
* libltdl/ltdl.m4: Added header checks from configure.in, so that
AC_LIB_LTDL is sufficient to compile ltdl.c.
Reported by Stephan Kulow <coolo@kde.org>.
* ltconfig.in (ltdll_obj): fixed typo: objdir -> $objdir
1999-12-12 Gary V. Vaughan <gary@gnu.org>
* ltconfig.in (cygwin*, mingw*, export_symbols_cmds): keep any
DATA tags associated with symbols by recent dlltool.
(cygwin*, mingw*, archive_expsym_cmds): Honor any DATA tags
found in the symbol list.
Reported by Jon Leichter <jon@symas.com>.

libltdl/configure.in.
Reported by Stephan Kulow <coolo@kde.org>.
From Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>
* ltconfig.in: split off the osf3 section, so that the osf4 and
osf5 sections can add `-msym' to arguments passed to the linker
for shared libs.
1999-12-03 Alexandre Oliva <oliva@lsd.ic.unicamp.br>
* ltconfig.in (ac_compile): Use $ac_ext instead of .c.
(ac_link): Likewise.

ac_compile.
Reported by Stephane Conversy <Stephane.Conversy@lri.fr>
* ltconfig.in (linux-gnu*): Disable hardcode_into_libs until it
works together with fast_install.

if set, we need to relink at install-time
1999-06-29 Thomas Tanner <tanner@ffii.org>
* NEWS: mention -no-fast-install, rename dummy to force
* doc/PLATFORMS: 1.3b passes all tests on GNU/Linux,
FreeBSD (2.2.6 and 3.1)

rename dummy to force, documented -no-fast-install,
AC_LIBLTDL_* must be called before AC_PROG_LIBTOOL,
documented hardcode_into_libs and striplib/old_striplib,
* ltconfig.in: search for strip program, added hardcode_into_libs

* ltmain.in: reimplemented hardcoding into libraries:
new relink mode, preserve all libtool args, relink libraries
when installing if necessary
added -no-fast-install flag, removed unnecessary `dlname'
initialization, use striplib/old_striplib for stripping libraries,
dlname is always soname or in library_names so we don't need
to handle different file names

an extracted and compiled ltdll.c, then don't delete, reextract
and recompile.
(cygwin, archive_expsym_cmds): Make sure the ltdll source has been
extracted and compiled before referencing the object, since there
are paths through the code which run archive_expsym_cmds without

just in case some sed does not support an empty command.
* ltconfig.in (link_static_flag, ac_cv_prog_cc_static): Use the
latter in the test.
1999-06-18 Thomas Tanner <tanner@ffii.org>
* ltconfig.in (bsdi4, deplibs_check_method): use a less restrictive
regex (reported by Chris P. Ross <cross@eng.us.uu.net>)
* ltmain.in: support `-dlopen dummy', define lt_preloaded_symbols
if dlself != no
* doc/libtool.texi (Compile and Link mode): document it,
documented the -Wc, -Wl flags, libtool does also support non C
source code
1999-06-18 Teun Burgers <burgers@ecn.nl>
* ltconfig.in: CR/LF fix for broken DJGPP bash
* ltmain.in: CR/LF fix for DJGPP
1999-06-18 Gary V. Vaughan <gary@gnu.org>
* ltmain.in (outputname): When generating the executable wrapper
script, $outputname already has the $exeext suffix, so we needn't
add it again.
1999-06-16 Gary V. Vaughan <gary@gnu.org>
* libltdl/configure.in (ac_cv_lib_dl_dlopen): missing "x" in test
comparison corrected.
* libltdl/ltdl.c (sys_wll_open): libltdl expects this function to
fail if it is unable to physically load the library. Sadly,
LoadLibrary will search the loaded libraries for a match and
return one of them if the path search load fails. Simulate a
failure in this case for compatibility with the other APIs.
Also, LoadLibrary takes the liberty of adding `.dll' to library
names passed without an extension, we now add a trailing `.' to
prevent this from happening.
1999-06-15 Gary V. Vaughan <gary@gnu.org>
* libltdl/ltdl.c (sys_wll_close): Strangely enough, Microsoft have
decided that LoadLibrary returns `0' for success, yet FreeLibrary
returns `0' for failure! The FreeLibrary call used to interpret
`0' as success for both functions.
1999-06-14 Thomas Tanner <tanner@ffii.org>
* ltconfig.in: use eval when setting have_dlfcn_h, reformatting
1999-06-12 Thomas Tanner <tanner@ffii.org>
* ltmain.in: store old archives in deplibs and old_deplibs,
retain the order of dependency libraries (even old archives),
determining the absolute directory name didn't work due to a typo,
add the library search paths of all dependency libraries when
linking a library (fixes IRIX 5.2 bug)
1999-06-10 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in: Reverted June 6's patch for new GNU ld output, it
is no longer needed, as ld reverted to the original format.
* NEWS: Likewise.
* ltconfig.in: When testing self-dlopening, test whether dlclose
crashes. On FreeBSD 3.1, it does. :-(
* libltdl/configure.in: Likewise.
* NEWS: Note work-around.
Reported by Pavel Roskin <pavel_roskin@geocities.com>
1999-06-09 Gary V. Vaughan <gary@gnu.org>
* ltconfig.in (exeext): autoconf's AC_EXEEXT uses "no" to indicate
no extension, and we must do the same in order to share the cache
value. Also we must ignore conftest.err which HPsUX (at least)
fills with gratuitous warnings.
(objext): for consistency, do the same as above.
Reported by Pavel Roskin <pavel_roskin@geocities.com>
1999-06-09 Pavel Roskin <pavel_roskin@geocities.com>
* ltconfig.in (exeext): Use quotes in the test, to prevent a
failure in sh.test.
1999-06-09 Gary V. Vaughan <gary@gnu.org>
* ltconfig.in: Reordered tests to be more like configure.in's
recommended order (programs first, then libraries, etc.).
Performed a manual ``constant folding pass'' (eg: s/eval "test
\"echo '$''{'lt_cv_dlopen'+set}'`\" != set/test
"${lt_cv_dlopen+set}" != set/).
s/test "${foo+set}" = "set"/test "X${foo+set}" = Xset/g
* ltconfig.in (link_static_flag): Accept, in order of decreasing
preference: the cached value; the default value for the current
host. Also test that the compiler accepts the flag, and cache
that result too.
* ltconfig.in (pic_flag): Accept, in order of decreasing
preference: the cached value; the default value for the current
host. Also test that the compiler accepts the flag, and cache
that result too.
1999-06-08 Gary V. Vaughan <gary@gnu.org>
* ltconfig.in (LN_S): Accept, in order of decreasing preference:
the cached value; an environment setting; ``ln -s'' if it works;
``ln'' if ``ln -s'' doesn't appear to work.
* ltconfig.in (objext): Accept, in order of decreasing preference:
the cached value; the result of a test object compilation.
* ltconfig.in (RANLIB): Accept, in order of decreasing preference:
the cached value; an environment setting; the first file called
``ranlib'' in the user's path.
* ltmain.in (exeext): Use $exeext when working out the names of
programs (but not the wrapper script itself due to a stupidity in
win32 which hardwires the .exe extension to the binary loader!).
* ltconfig.in (exeext): Now that the wrapper script tries to move
executables, we need to know whether they have an extension (ala
AC_EXEEXT). Since we can't rely on AC_EXEEXT having been called
in configure.in, we must be able to check for ourselves, though we
can look for a cached result incase AC_EXEEXT was called.
* ltconfig.in (cygwin, pic_flag): Force separate compilation of
objects for dlls vs. objects for static archives. Using a cpp
macro also allows us to decide whether or not we need to use
dllexport/import declarations.
* ltconfig.in (cygwin, need_version): Set to no, otherwise module
dll's end up with mighty long names!
1999-06-06 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in: Support new GNU ld --help output format.
* NEWS: Likewise.

1999-04-09 Thomas Tanner <tanner@gmx.de>
* NEWS, README: Motorola System V 4 support
* doc/PLATFORMS: added mk88-motorola-sysv4
* ltconfig.in: installed patch from Brian Ford <ford@vss.fsi.com>
to support mk88-motorola-sysv4
* doc/libtool.texi: some cleanups in the libltdl documentation
1999-04-07 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (--fallback-echo): Do not put an inline document and
an exec in the same if construct; otherwise the inline document
may not be removed.
* ltmain.in (--fallback-echo): Likewise.
Reported by John David Anglin <dave.anglin@nrc.ca>
* dryrun.test: It would still fail at random times, because `cp'
and `mv' are not guaranteed to preserve the timestamps of the
installed files. Instead of preserving them, just remove them
before the dry uninstall test. Redirect dry-run output to stderr,
so that it can be easily separated from the regular output.
1999-04-07 Thomas Tanner <tanner@gmx.de>
* NEWS: support for moved libraries
* libtool.m4: another DJGPP fix
1999-04-07 Alexandre Oliva <oliva@dcc.unicamp.br>
* doc/PLATFORMS: Updated to 1.3 for all platforms I've got. I'll
make sure 1.3 won't be released unless it passes all tests on
those platforms.
* doc/libtool.texi (Compile mode): Document potential problem and
work-around for `-c -o dir/foo.lo'.
* tests/dryrun.test: The constant modifications of libtool would
cause main.o to be updated at the wrong time; the new approach is
to modify the libtool script so that it enables dry run depending
on whether an environment variable is set or not. I've also moved
`after' and `before' to a directory deep within $objdir, instead
of creating it in ../tests.
* tests/Makefile.am (CLEANFILES): Removed.
1999-04-06 Alexandre Oliva <oliva@dcc.unicamp.br>
* tests/dryrun.test: We cannot rely on setting LIBTOOL, because
automake may use sub-makes, and the setting will not be propagated
to them on some makes. Instead, create a dry version of libtool
and switch between it and the original one before and after dry
runs.
* tests/Makefile.am (CLEANFILES): Added libtool-*, created by
dryrun.test.
* tests/dryrun.test: Use cmp instead of diff.
(before, after): Create them within ../tests.
(libtool): Set to `/bin/sh ./libtool' by default, but use LIBTOOL,
SHELL and top_builddir from the environment if available. For dry
runs, use "$libtool -n".
* tests/Makefile.am (CLEANFILES): Added before and after.
* ltmain.in: Do not create links to object files in dry runs.
1999-04-06 Thomas Tanner <tanner@gmx.de>
* ltmain.in: added a missing line of the ILD patch
* NEWS: improved DJGPP support
* doc/libtool.texi: removed hardcode_into_libs documentation
* libtool.m4: some DJGPP fixes
* ltconfig.in: ditto, reverted one of my previous patches: we need
to check for NM, removed the hardcode_into_libs support since
no platform seems to support it
* ltmain.in: some DJGPP fixes, removed the hardcode_into_libs support
1999-04-05 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (netbsd*, GNU ld): Support a.out shared libraries
* Makefile.am (CVS): allow command-line overriding of cvs
* ltconfig.in (exclude_expsyms): Exclude _GLOBAL_OFFSET_TABLE_ by
default, as most a.out platforms use it, and end up in trouble if
we preload it, so it's safer to rule it out by default, and
special case its removal from exclude_expsyms if someone ever
complains.
1999-04-05 Thomas Tanner <tanner@gmx.de>
* doc/libtool.texi: reorder tests to reflect execution order,
documented dryrun.test and depdemo*
* ltmain.in (lt_preloaded_symbols): dry-run mode bugfix
* tests/dryrun.test: new test to check whether the dry-run
mode works properly
* demo/run.test: removed the unnecessary test
* demo/Makefile.am: ditto
* ltmain.in: set the DLL search path on cygwin,mingw and os2
1999-04-04 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (sunos4*, GNU ld): -Bstatic is not enough for
deplibs.test to work with GNU ld; -Bshareable is needed here.
* ltconfig.in (ld_shlibs, amigaos*): Disable shared libs with
native ld too.
* ltconfig.in (sunos4*, GNU ld): Reordered.
* ltconfig.in (archive_cmds, sunos4*): Revert to -Bstatic; the
native linker doesn't even support -Bshareable, only GNU ld does.
Do not use `gcc -shared' in archive_cmds, it breaks deplibs.test.
* ltconfig.in: if ld_shlibs=no, set can_build_shared=no too,
otherwise it will just be disregarded. This would cause
netbsd/m68k with GNU ld a.out, and certainly many other platforms,
to incorrectly believe that shared libraries were supported, while
archive_cmds was empty, causing shared libraries not to be created
1999-04-03 Alexandre Oliva <oliva@dcc.unicamp.br>
* NEWS: improved support for AIX and HP/UX
1999-04-03 Thomas Tanner <tanner@gmx.de>
* NEWS: updated
* libtool.m4: check for main in libm instead of cos
* ltmain.in: cosmetic fixes, don't try to link libraries only once
(although it's not necessary on many platforms and looks ugly...),
1999-04-02 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in (convenience): fixed race condition when more than one
library was linked with the same convenience library by
uniquifying the extract directory. It is now named after the new
library *and* the old one, and lives in the objdir of the new one.
* ltmain.in (-L*): do not abort just because a directory specified
with -L does not exist; just warn and discard it
* depdemo/l1/Makefile.am (AUTOMAKE_OPTIONS): no-dependencies
* depdemo/l2/Makefile.am (AUTOMAKE_OPTIONS): ditto
* depdemo/l3/Makefile.am (AUTOMAKE_OPTIONS): ditto
* depdemo/l4/Makefile.am (AUTOMAKE_OPTIONS): ditto
* ltconfig.in (archive_cmds, sunos4*): where we used -Bstatic, we
should have been using -Bshareable
* demo/Makefile.am (CLEANFILES): clean EXTRA_* from deplibs-check
* libtool.m4 (LDFLAGS, LIBS): pass them to ltconfig, for the tests
that involve linking
* Makefile.am (LDFLAGS, LIBS, libtool, clibtool): ditto
* tests/Makefile.am (CFLAGS, CPPFLAGS, LDFLAGS, LIBS): set
(LDFLAGS, LIBS, TESTS_ENVIRONMENT): pass them down
1999-04-02 Erez Zadok <ezk@cs.columbia.edu>
* doc/PLATFORMS: 1.2f ok on various versions of hpux cc
1999-04-02 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (link_all_deplibs): set to unknown by default
* ltmain.in: test != no, not = yes
* doc/libtool.texi: document unknown
1999-04-01 Thomas Tanner <tanner@gmx.de>
* doc/libtool.texi: documented deplibs.test
* demo/Makefile.am: moved testsuite specific declarations to the end,
the deplibs check is now optional
* libltdl/configure.in: read libtool --config only once,
merged AC_SYS_SYMBOL_UNDERSCORE+AC_SYS_NM_PARSE from libtool.m4
* libtool.m4: AC_SYS_SYMBOL_UNDERSCORE+AC_SYS_NM_PARSE were not
used, lt_dlopen and silent may be empty, AC_SYS_LIBTOOL_CYGWIN
no longer necessary
* ltconfig.in: NM is already checked in libtool.m4,
* ltmain.in: always link all static dependency_libs
* tests/Makefile.am: added deplibs.test
* tests/demo-exec.test, demo-inst.test: removed hell0
* tests/deplibs.test: new test to test the deplibs_check_method
1999-03-31 Thomas Tanner <tanner@gmx.de>
* ltmain.in: always link a library before its dependency libs
* mdemo/Makefile.am: test -export-symbols-regex
1999-03-30 Thomas Tanner <tanner@gmx.de>
* doc/libtool.texi: fixed a typo
* libtoolize.in: add the libtool scripts to libltdl.tar.gz
* libtool.m4: don't AC_SUBST(USE_SYMBOL_UNDERSCORE),
AC_CHECK_LIBM sets LIBM, AC_LIBLTDL_INSTALLABLE doesn't work
when libltdl is already installed
* *demo/Makefile.am: use LIBM
* *demo/configure.in: AC_SUBST LIBM
* libltdl/configure.in: use ac_cv_sys_symbol_underscore instead of
USE_SYMBOL_UNDERSCORE
* ltconfig.in: added link_all_deplibs variable
* doc/libtool.texi: document it
* ltmain.in: always search for libname.la - don't eval libname_spec,
when linking libraries against static ones just print a warning
and add them to dependency_libs, add -lc before deplibs,
always link all dependencies of a static library or if
link_all_deplibs is yes, hardcode library paths if
hardcode_into_libs is no, don't link against dependency_libs
that already are deplibs
1999-03-30 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (aix4*, collect2name): make sure collect2 exists
before running string on it, to avoid errors on old gccs
Reported by Erez Zadok <ezk@cs.columbia.edu>
* ltconfig.in (aix4*, hardcode_libdir_flag_spec): unless we're
using gcc with old collect2, use -b libpath to hardcode the
library search path
* ltmain.in, ltconfig.in: reverted most of the quoting changes
from 1999-03-25; Gary's delay_variable_subst patch from 1999-02-19
obviates it. Keep only quoting of $PATH, for uniformity with
other systems that already did it
1999-03-29 Gary V. Vaughan <gary@gnu.org>
* libltdl/ltdl.c (lt_dladdsearchdir): Forgot to mallocate the
extra byte of memory for the teminating NUL, and forgot to
strcpy the original path in to the new memory before appending
the new path compononent.
1999-03-27 Thomas Tanner <tanner@gmx.de>
* NEWS: updated
* README: updated (BeOS support, no longer shared libraries
support for AmigaOS), cleanups, we have now two mailing lists
* REAMDE-alpha: autogen -> bootstrap, we have now two mailing lists
* THANKS: added Xavier Pianet
* doc/PLATFORMS: BeOS works
* doc/libtool.texi: we have now to two mailing lists,
updated -dlopen self documentation, documented libltdl's license,
put each author in a separate line,
inter-library dependencies on uninstalled libtool libraries are
now supported, cleanups and minor corrections
* libltdl/COPYING.LIB: new file
* libltdl/ltdl.[ch]: added special exception to the LGPL license
* libtool.spec: removed, it was outdated
* Makefile.am: removed libtool.spec
* ltmain.in: use TMPDIR when possible, create a subdirectory
in the temporary directory, added -export-symbols-regex to the help,
1999-03-25 Alexandre Oliva <oliva@dcc.unicamp.br>
* demo/Makefile.am: create a static library, link two libtool
archives with it, then link the program hell0 with both
* demo/hell1.c, demo/hell2.c: dummy files used to create the
libtool archives without introducing symbol conflicts
* tests/demo-exec.test, tests/demo-inst.test: run the new program
* ltconfig.in (irix5*, irix6*, deplibs_check_method): pass_all
* ltmain.in ($PATH): instead of modifying the PATH, better prevent
its expansion the first time *_cmds variables are eval'ed. Modify
$show within loops that eval them so as to expand variables
* ltconfig.in (*_cmds): quote $ so that they're not expanded by
the first eval
1999-03-25 Gary V. Vaughan <gary@gnu.org>
* ltmain.in ($PATH): Expand any tildes in the users path to the
contents of $HOME to avoid problems with *_cmds splitting and
evaluation.
1999-03-24 Thomas Tanner <tanner@gmx.de>
* TODO: support -dlopen for libraries
* doc/PLATFORMS: Erez Zadok reported that libtool works on bsdi 4.0.1
* doc/libtool.texi (libltdl): libltdl supports BeOS
* libltdl/ltdl.c: shlib_ext was declared even if LTDL_SHLIB_EXT
didn't exist, partially reverted my previous patch: BeOS will
automatically search in ADDON_PATH
* ltmain.in: don't allow relative run-paths, fixed a typo in a warning,
ignore -dlopen self for libraries and objects,
only accept -L paths that exist, minor cleanups,
bugfix: add -lc for normal libraries, not convenicence libraries
removed offensive warnings/comments
1999-03-24 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (ld_shlibs, amigaos*): disable shared libraries
1999-03-23 Gary V. Vaughan <gary@gnu.org>
* libltdl/configure.in: the sed expression for finding the shared
library extension used to think the . in [.] for the cygwin
shared_library_names_spec was the start of the extension!! We now
remove anything in square brackets (assuming that the square
brackets delimit a sed or expr expression which is not part of the
extension) before looking for the extension.
* TODO (cygwin): food for thought re: mutually dependant dlls.
1999-03-21 Alexandre Oliva <oliva@dcc.unicamp.br>
* tests/build-relink.test: if we relink and have hardcode_direct,
removing an uninstalled library breaks an uninstalled program
* doc/libtool.texi: documented convenience libraries
* TODO: removed entry about it
* tests/*-unst.test: if directory is not configured, skip it
* tests/demo.test, tests/mdemo.test: unused, removed
* tests/depdemo.test: ditto
1999-03-20 Thomas Tanner <tanner@gmx.de>
* doc/libtool.texi (link mode): documentation for -module updated
* ltconfig.in: fast-install mode doesn't work for
hardcode_into_libs=yes
* ltmain.in: bugfix: "-dlopen self [-all]-static" wouldn't use
dlopen_self_static, automatically enable -export-dynamic when
using "-dlopen self", always make run-paths absolute,
ignore -lc only on platforms that don't have such a library,
cleanups in the ILD code, find even installed libtool libraries
that were moved, before generating the DLL-import library we need
to set libname, improved hardcoding of shlibpath for libraries,
don't generate an installable pseudo-library for convenience
libraries, bugfix: export_symbols would be removed immediately
before it is used
1999-03-19 Thomas Tanner <tanner@gmx.de>
* use the same header in all configure.in's and Makefile.am's
* NEWS: improved support for BeOS and Cygwin
* TODO: ILD branch was merged, all internal variables and macros
are now documented
* demo/Makefile.am: use $(LIBS) instead of -lm
* doc/libtool.texi: documented new variable hardcode_into_libs
and thread_safe_flag_spec, renamed all AM_ENABLE/DISABLE_* macros
to AC_*, documented AC_DISABLE_FAST_INSTALL and AC_LIBTOOL_DLOPEN
* libltdl/ltdl.c: added two new error messages (cannot_open_error,
cannot_close_error), use them where approriate,
BeOS support (thanks to Xavier Pianet), on BeOS search modules
additionally in ADDON_PATH
* libtool.m4: rewrote AC_CHECK_LIBM: BeOS and Cygwin don't have
libm and *-ncr-sysv4.3* requires libmw
* ltconfig.in: don't check for LoadLibrary, hardcode dlopen
configuration for BeOS and Cygwin
* ltmain.in: fix sourcing of .la files on Solaris
(patch by Raja R Harinath)
1999-03-19 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (sunos4*, with_gnu_ld, hardcode_minus_L): remove, we
have -rpath
(aix4*, without_gnu_ld, hardcode_shlibpath_var): unsupported is
default
(hpux9*, hpux10*, hpux11*, archive_cmds): drop +s, unneeded here
(hpux9*, hpux10*, hpux11*, hardcode_libdir_flag_spec): add +s
before +b
(hpux9*, hpux10*, hpux11*, shlibpath_overrides_runpath): since +s
appears before +b, set it to yes
(hardcode_shlibpath_var, hardcode_action): do not use
shlibpath_var to specify the compile-time search path; it loses,
and we may end up linking with pre-installed older versions of
libraries instead of yet-to-be-installed ones
(*, hardcode_direct, hardcode_minus_L): remove entries that set
them to no, that is default
* demo/Makefile.am (hc-direct, hc-libpath, hc-minusL): link with
$$hardcode_libdir_flag_spec, if available, with libdir=$(libdir),
to make sure the hardcode_* variables will produce the expected
results even in the presence of a hardcoding flag; depend on
libhello.la having been installed already
(hc-libflag): link with the installed library, but try to
hard-code the uninstalled one
* doc/libtool.texi: document the changes
* tests/*.test: when a test fails, skip tests that depend on it.
If a certain configuration is not supported, skip all its tests.
* doc/libtool.texi: reorder tests to reflect execution order
* tests/noinst-link.test: new test
* tests/Makefile.am (TESTS): added noinst-link.test
* doc/libtool.texi: document it
1999-03-19 Gary V. Vaughan <gary@gnu.org>
* ltmain.in (dependency_libs): There is no reason to infer that
the pseudo library is invalid if dependency_libs='' at
install-time, or else libltdl/libltdl.la is invalid!!
1999-03-18 Thomas Tanner <tanner@gmx.de>
* merged my inter-library dependencies code from the ILD branch:
* NEWS: inter-library dependencies are now supported
* configure.in: add the depdemo subdirectory
* depdemo/*: new demo to demonstrate inter-library dependencies
* tests/depdemo*: new tests for depdemo
* ltconfig.in: added hardcode_into_libs (whether library paths
should be hardcoded into the libraries),
it currently defaults to 'no'
* ltmain.in: new internal 'relink' mode to relink libraries
on platforms with hardcode_into_libs=yes, save command line
arguments in libtool_args, accept relative -L directories,
ignore -lm on BeOS and Cygwin, always ignore -lc,
handle -l, -L and .la arguments later, always make the library
installation directory (-rpath) absolute, in relink mode don't
delete the not-relinked library and exit immediately after relinking,
try to find already-installed libtool libraries that were specified
using -l, support hardcoding of library paths into libraries too,
export shlibpath before linking libraries, and a lot of other
big changes that I don't want to describe here... please read
the source.
* merged Gary's Win32 code from the ILD branch:
* NEWS: Win32 DLLs are now supported
* TODO: removed .a library namespace clash for win32. It is
now resolved.
* ltconfig.in (cygwin, library_names_spec): removed $libname.a.
Creating a dll with libtool no longer creates an import library.
* ltconfig.in (extract_expsyms_cmds): Create $objdir if it does
not exist -- i.e. we need to generate import an import library
in a directory which has no libs of its own.
* doc/libtool.texi (old_archive_from_expsyms_cmds,
extract_expsyms_cmds): documented these new variables.
* ltconfig.in (extract_expsyms_cmds): New variable. Commands to
extract the exported symbol list from a dll.
(old_archive_from_expsyms_cmds): New variable. Commands to build
an old archive from the extracted expsyms list.
* ltmain.in: run the cmds in extract_expsyms_cmds and
old_archive_from_expsyms_cmds as necessary.
* ltconfig.in (cygwin, old_archive_from_new_cmds): no longer
required.
* ltconfig.in (cygwin, shlibpath_overrides_runpath): I'm not even
sure whether win32 honours the runpath at all when searching for
a dll to load! Anyway, when set to yes this prevents a gratuitous
warning.
* ltmain.in (deplib): The cygwin environment doesn't actually have
-lm, and although the linker fakes having one, specifiying it to
libtool will break ILD, so we ignore it when generating
dependencies.
1999-03-17 Gary V. Vaughan <gary@gnu.org>
* doc/PLATFORMS: Thanks to Alexandres changes below, both my
hp boxes pass the entire test suite.
1999-03-17 Alexandre Oliva <oliva@dcc.unicamp.br>

at the right place)
1999-03-14 Alexandre Oliva <oliva@dcc.unicamp.br>

at GNU
1999-03-14 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (bsdi4*, sys_lib_search_path_spec,
sys_lib_dlsearch_path_spec): fix thinko in variable names; add
standard directories
* ltmain.in (exclude_expsyms): exclude symbols before sorting,
otherwise only the sorted list will have them excluded
* ltconfig.in (file_magic_cmd, file_magic_test_file, freebsd-elf*,
bsdi4*): use full pathnames when possible
* Makefile.am (all-recursive): depend on ACINCLUDE_M4_LIST
(all-local, check-local): remove, unused
* doc/PLATFORMS: updated platforms tested on 1.2f-pre; clean up;
reorder; untabify
* config.guess, config.sub: updated from GNU common
* doc/libtool.texi: notes on thread-safety problems of
libltdl/dlopen on GNU/Linux and FreeBSD
* ltconfig.in (aix3*, aix4*): GNU ld on AIX is very broken: it
cannot create working shared libraries. Print a warning
suggesting the user not to use it and disable shared libraries.
1999-03-13 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (global_symbol_to_cdecl): was reset before trying
`symprfx=_', rendering the test with `_' useless
* doc/libtool.texi (AM_PROG_LIBTOOL): eliminate overfull boxes
* doc/libtool.texi: complete dlopening/libltdl documentation
* ltconfig.in (osf3*, osf4*, deplibs_check_method): pass_all does
not really work; use file_magic instead.
(osf3*, osf4*): customize sys_lib_[dl]search_path_spec
* ltconfig.in (file_magic_test_file): new variable; if set, it
will be used as an argument for $file_magic_cmd to test whether
the regex in deplibs_check_method matches its output
(file_magic_cmd): use full pathnames whenever possible
* ltconfig.in (sys_lib_dlsearch_path_spec): new variable, that
lists the system *run-time* search path. Listed directories are
not implicitly hard-coded into executables.
* ltmain.in: use it, but *never* discard -R flags
* doc/libtool.texi: document it
* NEWS: ditto
Reported by Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* tests/sh.test: look for `$Xsed' without `$echo "X...'
* ltconfig.in, ltmain.in: fixed a few such occurrences
* ltmain.in (-static, -all-static): revert March 11's patch, I was
barking up the wrong tree
1999-03-12 Thomas Tanner <tanner@gmx.de>
* libltdl/ltdl.c: removed FILENAME_MAX since LTDL_FILENAME_MAX
is sufficient and doesn't break HP/UX
1999-03-11 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in: (global_symbol_pipe) extract symbol tag from the
output of NM too
(global_symbol_to_cdecl): new variable; convert the output of
global_symbol_pipe to valid C declarations; on HP/UX, convert
text symbols to function declarations
* libtool.m4: similar modifications
* doc/libtool.texi: document new variable
* ltmain.in: use global_symbol_to_cdecl to generate lt_dlpreopened
symbols; avoid extracting symbol lists from dlpreopened files
twice; do not filter symbols from dlpreopened libraries
* TODO: fixed HP/UX dlpreopening problem
* ltmain.in (-static, -all-static): set dlopen_self to
$dlopen_self_static regardless of link_static_flag or pic_flag
* ltmain.in: FreeBSD bug that needs symbol table compiled with
-fPIC is fixed in release 3.1; use it only for 2.* and 3.0
1999-03-11 Thomas Tanner <tanner@gmx.de>
* ltmain.in: when building a library it doesn't make
sense to remove a relinked program ("lt-" prefix)
1999-03-11 Alexandre Oliva <oliva@dcc.unicamp.br>
* mdemo/main.c (main, test_dl, test_dlself): propagate error
conditions better, to avoid false positives

*all* dlopen_* variables are set to unknown
1999-03-11 Thomas Tanner <tanner@gmx.de>
* ltmain.in: delete the old output files (incl. the relinked binary)
before linking.
* ltconfig.in: replaced `configure' with $progname and all
line numbers with @LINENO@
1999-03-11 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/ltdl.c (strdup): cannot return str when it's NULL
because of const correctness
1999-03-10 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/ltdl.c (strdup): always use our own, because the
standard strdup won't use lt_dlmalloc
* ltconfig.in (dlfcn.h): function definition may cause warnings;
define variable instead
* ltmain.in: properly create an export file for a program,
avoiding error messages about not finding it
* TODO: need to document AC_LIBLTDL_*; static self dlopening
problem fixed
* libtool.m4 (AC_LIBTOOL_DLOPEN): just set lt_dlopen=yes
(AC_LIBTOOL_SETUP): if lt_dlopen=yes, add --enable-dlopen to
libtool_flags; drop --enable-dlopen-self
* ltconfig.in: perform all the dirty work of testing for dlopening
support, because we need platform-dependent equivalents for
-export-dynamic, for self dlopening, and -static, for static self
dlopening
(dlopen_self_static): new configuration variable that is set to
yes only if static programs can dlopen themselves
* ltmain.in (-static, -all-static): dlopen_self=dlopen_self_static
* libltdl/configure.in (libltdl_cv_need_uscore): do not assume
dlfcn.h and LTDL_LAZY exist; use LTDL_GLOBAL and LTDL_LAZY_OR_NOW.
This test is likely to fail if self-dlopening does not work,
especially because we do not link the program with
-export-dynamic. Let's just hope that platforms whose symbol
names start with underscores will also accept underscores for
dlopen. We should probably use libtool to compile and link this
test, so that we can use -export-dynamic.
* mdemo/Makefile.am (@LIBLTDL@): depend on ../libltdl/config.h
* configure.in: fix AC_OUTPUT_COMMANDS for ltconfig and ltmain.sh
so that they work if srcdir is relative too
* libtool.m4 (AC_LIBLTDL_INSTALLABLE, AC_LIBLTDL_CONVENIENCE):
avoid introducing multiple --enable options when re-running
config.status
* libltdl/configure.in: if enable_ltdl_* is not set, assume no
* configure.in: if enable_ltdl_install is not set, enable it
* libltdl/configure.in: only assume implicit installation if
libltdl was libtoolized. If not, print a warning message
suggesting the use of --enable-ltdl-install or of one of the
AC_LIBLTDL_* macros.
* libtool.m4 (AC_LIBTOOL_SETUP): new macro, that does all the
configure-work that AC_PROG_LIBTOOL used to do; add
--cache-file=$cache_file to libtool_flags
(AC_PROG_LIBTOOL): call AC_LIBTOOL_SETUP, save the cache, run
ltconfig and reload the cache
* configure.in: run AC_LIBTOOL_SETUP, then set LIBTOOL_FLAGS to
libtool_flags
* ltconfig.in: support --cache-file switch. If it is used, load
the cache in the beginning and save it just before terminating
* tests/Makefile.am (TESTS): run demo-nofast before demo-shared
* configure.in: create ltconfig and ltmain.sh at the end of
config.status, if they do not exist. This fixes the bootstrap
problem reported by Erez Zadok <ezk@cs.columbia.edu>
1999-03-10 Thomas Tanner <tanner@gmx.de>
* NEWS: sorted by importance
* Makefile.am: set LIBTOOL_FLAGS when generating libtool
* configure.in: check for dlopen support and set LIBTOOL_FLAGS
accordingly
* configure.in: fix spacing for --disable-ltdl-install,
always configure libltdl, add libltdl/acinclude.m4 to
ACINCLUDE_M4_LIST, disable installation of libltdl if necessary
* libltdl/Makefile.am: set version info for libltdl.la
* libltdl/configure.in: don't check whether
enable_ltdl_convenience/install was set so that libltdl
can be used as independent package (libltdl.tar.gz) without
the need to use --enable-ltdl*
* libltdl/ltdl.c: minor cleanups, allocate the line cache
dynamically (lt_dlopen)
1999-03-10 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/ltdl.c (lt_dlopen): some preprocessors choke if the `#'
of `#define' is not in column 1; let's go back to fortran! :-)
Add #undefs too, to avoid potential warnings or errors.
1999-03-09 Alexandre Oliva <oliva@dcc.unicamp.br>
* libtool.m4 (AC_LIBLTDL_INSTALLABLE, AC_LIBLTDL_CONVENIENCE):
renamed convenience libltdl, dropped toinst hack for installable
* libltdl/Makefile.am: ditto
* libltdl/configure.in: ditto; abort if none of the macros is used
* ltmain.in: $output_objdir/$objdir/ -> $output_objdir/lt-
1999-03-09 Thomas Tanner <tanner@gmx.de>
* libltdl/ltdl.c (lt_dlopen): don't hardcode the length of the
constant strings
1999-03-09 Alexandre Oliva <oliva@dcc.unicamp.br>
* Makefile.am (install-data-hook): install libltdl as a directory,
not as a tar-file, so that we do not modify the build tree at make
install time
* libtoolize.in (ltdl, ltdl_tar): update
* configure.in, Makefile.am, NEWS: install libltdl by default
* libtool.m4 (AC_LIBLTDL_INSTALLABLE, AC_LIBLTDL_CONVENIENCE):
new macros
* NEWS: ditto
* libltdl/configure.in: if none of the new macros or configure
arguments are used, warn and build convenience library only
* libltdl/Makefile.am: conditionally build convenience libltdl.la
* mdemo/configure.in: use AC_LIBLTDL_CONVENIENCE
* mdemo/Makefile.am: refer to @LIBLTDL@
1999-03-09 Gary V. Vaughan <gary@gnu.org>
* NEWS: updated.
1999-03-08 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in: extract symbols from program objects to nlist first,
then translate them to the export_symbols format. Now it works,
but it appears to be needlessly extracting the symbol list from
dlpreopened libraries twice
* ltmain.in: temporarily disable dlopen_self when linking with
-static or -all-static, until we figure out how to test whether it
works at configure time
* TODO: remember to fix this later
* tests/build-relink.test: when hell is expected to fail, run it
within a subshell and redirect stderr to stdout, so that dynamic
linker errors are only printed in verbose mode
* ltmain.in (hardcode_libdir_separator, compile_rpath,
finalize_rpath): only substitute hardcode_libdir_flag_spec if
hardcode_libdirs is non-empty
* libtool.m4 (AC_LIBTOOL_DLOPEN): do not depend on the existence
of dlfcn.h nor on the definition of RTLD_LAZY
* tests/build-relink.test: hellT was renamed to lt-hell
* libltdl/Makefile.am (@TOINST@/libltdl.la): do not hide the
command that creates the TOINST directory; remove `-o $@' from the
LINK command, $(LINK) already contains it.
1999-03-08 Thomas Tanner <tanner@gmx.de>
* doc/libtool.texi (tests): documented demo-nofast.test and
renamed cdemo* to demo*
1999-03-08 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/Makefile.am, libltdl/configure.in, mdemo/Makefile.am:
libltdl must not be renamed; if there's a problem with the install
option, let's fix it, not just work around it by breaking code of
users of the convenience library
* tests/build-relink.test: link broken libhello.la with at least
one libtool object
1999-03-08 Thomas Tanner <tanner@gmx.de>
* TODO: updated (libltdl build problem fixed)
* doc/libtool.texi (libltdl interface): removed the line which
promised that lt_dlopen will return NULL if it can't resolve all
symbols
* libltdl/Makefile.am, libltdl/configure.in: fixed build problem:
renamed the convenience library to libltdlc.la and the
installed version to libltdl.la
* ltmain.in (wrapper script): replaced the "T" suffix of the program
file name with a "lt-" prefix
* mdemo/Makefile.am: use libltdlc.la
* tests/Makefile.am, tests/demo-nofast.test: added demo to
test --enable-fast-install=no
1999-03-07 Alexandre Oliva <oliva@dcc.unicamp.br>
* tests/Makefile.am (TESTS): run hardcode before build-relink
trashes libhello.la
* tests/hardcode.test (need_prefix): set to yes so that _inst is
not removed
* ltmain.in (compile_command): append finalize search path to
compile search path
* tests/build-relink.test: new; check shlibpath_overrides_runpath
* tests/Makefile.am (TESTS): add build-relink.test; remove
hardcode.test duplicates
* doc/libtool.texi: document it
* ltmain.in (relink_command): do not prepend cd `pwd` to it, the
scripts already enters the correct directory, and expanding the
pathname would prevent the build tree from moving
* ltconfig.in (enable_fast_install): force it to no only if we
need relink; in the other cases, set it to needless
* ltmain.in (fast_install): if needless, set relink_command empty
* doc/libtool.texi (fast_install, shlibpath_overrides_runpath):
document the new behavior
* ltconfig.in (enable_fast_install): test whether it can be forced
off after shlibpath_overrides_runpath and enable_shared are set
1999-03-07 Thomas Tanner <tanner@gmx.de>
* TODO: updated
* NEWS: updated
* TODO: scheduled some items for next release/future
* demo/configure.in: use AC_LIBTOOL_DLOPEN
* libtool.m4: added AC_ENABLE/DISABLE_FAST_INSTALL macro
* ltconfig.in: added --disable-fast-install flag
* ltmain.in: partially reverted Alexandre's patch and implemented
on-demand linking in such a way that the old developer-friendly
linking style is optional,
don't hardcode library paths that are in the system search path,
fixed a typo in lib_search_path,
implemented -export-symbols-regex for programs
1999-03-06 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/ltdl.c (LTDL_LAZY_OR_NOW): renamed from LTDL_NOW; prefer
LAZY loading because it's much faster and NOW is apparently
partially broken on FreeBSD
Reported by Archie Cobbs <archie@whistle.com>
* ltconfig.in (archive_expsym_cmds, solaris, without_gnu_ld):
$lib.exp already starts with $objdir/
Reported by Godmar Back <gback@cs.utah.edu>
* ltmain.in (freebsd): compile symbol table file with pic_flag
only on FreeBSD and when not static linking; it's been causing
trouble on platforms such as OpenBSD.
1999-02-26 Gary V. Vaughan <gary@gnu.org>
* libtool.m4 (cygwin): s/\\(mingw\\|cygwin\\)32/\\1/g. Must've
missed this file when I changed to cygnus' new sanction name.
* ltconfig.in (sub_uncdrive): removed. This won't work with
the next version of cygwin.
(sub_uncdir): removed. We use <drive>:/path/to/executable now.
* libtool.m4 (AC_PROG_LD): removed sub_uncdrive and sub_uncdir.
1999-02-25 Thomas Tanner <tanner@gmx.de>
* TODO: added items for next alpha release, ILD etc.
* libltdl/ltdl.c: removed unnecessary check from presym_sym,
fixed bug in lt_dlclose, allow lt_dlopenext(NULL),
set deplibs for lt_dlopen(NULL)
1999-02-24 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in (file_magic_regex): sed `10q' is faster than `11,$d'
1999-02-22 Thomas Tanner <tanner@gmx.de>
* ltconfig.in (dlopen, dlopen_self): default is unknown
* ltmain.in: fixed -dlopen self, print a warning
if -dlopen is used without AC_LIBTOOL_DLOPEN
* mdemo/Makefile.am: use -dlopen self
1999-02-22 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in: added missing mkdir $progdir for on-demand executable
* ltmain.in: create on-demand executable as $progdir/$$-$program,
and rename it to $progdir/$program only when it's finished, to
avoid race conditions. We can still get the program linked
multiple times, if multiple instances are started simultaneously
and the program does not exist, but they are very unlikely to
interfere with each other. There's still a possibility that one
process removes the $program another has just created, and doesn't
replace it before the other tries to run it, in a system whose
`mv' is not atomic, so it will $rm then $mv, but so what? :-)
Locking files have been avoided to prevent dead-locks in case they
are left over after a reboot or crash.
* TODO: removed ILD, soon to be merged, and added convenience
libraries docs
* ltconfig.in (irix5*, irix6*, shlibpath_overides_runpath): yes
* ltmain.in: remove on-demand executable in the proper place, and
just warn if it can't be removed; add wrapper code to test whether
the install-executable is newer than the build-executable, to
relink it when it appears to be out-of-date
* libltdl/configure.in: check for dld.h
* libltdl/ltdl.c: include dld.h
(dld_open) it's spelled memory_error, not no_memory_error
Reported by Stefan Burstroem <f94sbu@efd.lth.se>
* ltmain.in: fix typos in my last change (s/ocmpile/compile/)
1999-02-21 Thomas Tanner <tanner@gmx.de>
* libltdl/ltdl.c (lt_dlopen): use newhandle instead of handle
when dlopening the executable
* libtool.m4 (AC_LIBTOOL_DLOPEN): removed the redundant "yes: "
prefix for lt_cv_dlopen, renamed lt_cv_dlopen_LIBS
to lt_cv_dlopen_libs (more consistent)
* ltmain.in: implemented -dl[pre]open self, necessary for
lt_dlopen(NULL), generation of exported symbols was broken
1999-02-20 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in: avoid duplication of -L switches, it sometimes breaks
IRIX 5.2's linker
* ltconfig.in (freebsd*, finish_cmds): expand objformat here
Reported by Vladimir Kushnir <kushn@mail.kar.net>
1999-02-20 Vladimir Kushnir <kushn@mail.kar.net>
* ltconfig.in (freebsd-elf*, need_version, need_lib_prefix): no
(freebsd-elf*, library_names_spec): add $libname.so instead of
$libname.so$versuffix; add $libname$release.so
1999-02-20 Alexandre Oliva <oliva@dcc.unicamp.br>
* doc/libtool.texi: remove ticks from menu items; it breaks TeX
Reported by Erez Zadok <ezk@cs.columbia.edu>
* ltmain.in: fixes for export-symbols dry-run
* ltconfig.in (shlibpath_overrides_runpath): new variable;
determines whether LD_LIBRARY_PATH or equivalent can be used to
override a hard-coded library search path; default to unknown
(linux-gnu*): set it to no
(solaris*, sunos4*): set it to yes
* ltmain.in (build_libdirs_flags, build_libdirs, build_rpath): if
shlibpath_overrides_runpath is not yes, arrange that wrapper
scripts create, on demand, programs that use uninstalled libraries
* doc/libtool.texi: document it
* libtool.m4 (AC_LIBTOOL_DLOPEN): check for dlopen in libc before
trying in dl. Add the actual dlopening type to lt_cv_dlopen, and
add any needed libraries to lt_cv_dlopen_LIBS. Add test for
MS-Windows' LoadLibrary. Check whether a program can dlopen
itself only if we really have dlopen(), not some equivalent
function, but leave room for testing with other mechanisms.
(AC_PROG_LIBTOOL): assume some form of dlopen, but not
dlopen(NULL), is available if AC_LIBTOOL_DLOPEN is not used, for
backward compatibility.
1999-02-20 Archie Cobbs <archie@whistle.com>
* libltdl/ltdl.c (lt_dlopen): use newhandle instead of handle
where appropriate, when dlopening a non-libtool library
1999-02-19 Gary V. Vaughan <gary@gnu.org>
* ltconfig.in (export_symbols_cmds): renamed from
export_symbols_cmd.
(cygwin, mingw): Be sure to compile the ltdll.c object before
extracting the exported symbol list. Extract only the names
of the exported symbols from the def file [otherwise we might
run into trouble with -export-symbols-regex].
(archive_expsym_cmds): Regenerate the def file from the symbol
export list.
(delay_variable_subst): New sed expression to allow us to delay
evaluation of $foo in a double_quote_subst evaluated variable by
using \$.
* ltmain.in (export_symbols_cmds): evaluate each ~ delimitted cmd
separately.
* doc/libtool.texi (libtool script contents): new paragraph to
explain the difference between _cmd and _cmds suffixes for
variable names.
(export_symbols_cmds): renamed from export_symbols_cmd.
1999-02-18 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (ld_shlibs): move -soname and similar flags to the
end of archive_cmds and archive_expsym_cmds, so as to prevent
gcc's collect2 from inserting an object file between -soname and
the library name
* ltconfig.in (openbsd*, netbsd*, library_names_spec): append
alternate name without ${release}, otherwise build fails when
-release is used
1999-02-18 Gary V. Vaughan <gary@gnu.org>
* ltconfig.in (archive{,_sym}_commands): Be careful not to
re-export the dll entry points DllMain@12, _cygwin_dll_entry@12 and
_cygwin_noncygwin_dll_entry@12 to avoid bugs with the wrong entry
function being called with inter-dll dependencies.
Reported by DJ Delorie <dj@delorie.com>
* THANKS: Added DJ Delorie, since his code inspired the impgen.c
program and because he has patiently answered all of the
irritating dll and win32 questions I have fired at him.
* ltmain.in (version_type): Oops. Irix versioning implies that
major version numbers are 1 based (not zero based). Fixed.
* ltmain.in (version_type): Implement irix versioning.
* ltconfig.in (irix{5,6}*): Use new irix shared object versioning.
* TODO: remove irix versioning from TODO list.
* ltmain.in (impgen.c): Added a new embedded C file that can be
used under win32 to extract a def file (symbol export list) from a
dll that has none. Code to use it might need to wait for the ILD
merge before it will be useful...
1999-02-18 Thomas Tanner <tanner@gmx.de>
* TODO: updated
* autogen: only libltdl needs autoheader
* doc/libtool.texi (link mode): documented -export-symbols-regex
and updated -export-symbols
* doc/libtool.texi (script contents): documented
always_export_symbols, export_symbols_cmd, exclude_expsyms,
include_expsyms, dlopen and dlopen_self
more detailed description of need_lib_prefix
* ltconfig.in: a "'" was missing in the default value
of export_symbols_cmd
* ltmain.in: implemented -export-symbols-regex
1999-02-17 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in: (freebsd2*, sunos4*, exclude_expsyms): exclude
_GLOBAL_OFFSET_TABLE_
* ltmain.in: implement exclude_expsyms with egrep
* libltdl/ltdl.c (lt_dlmalloc, lt_dlfree): SunOS' cc can't cope
with argument lists, we __P even in the definition
1999-02-15 Thomas Tanner <tanner@gmx.de>
* cdemo/Makefile.am: renamed *foo1 to *foo, removed $(MATH_LIB)
* cdemo/foo1.c: renamed to foo.c
* libltdl/ltdl.c: eliminated lt_dltype, in presym_open():
search for @PROGRAM@ if filename == 0, in lt_dlopen():
fixed bug for filename == 0
* libltdl/ltdl.h: use __P macro for lt_dlmalloc/free
* libtool.m4: new macro AC_LIBTOOL_DLOPEN: checks for dlopen
and dlopen(NULL) support
* ltconfig.in: added new variables dlopen and dlopen_self,
--enable-dlopen[-self] flags for AC_LIBTOOL_DLOPEN
* ltmain.in: use dlopen[_self], dlpreopen files if there's no
dlopen support, build lt_preloaded_symbols only if
-dl[pre]open was used, include program symbols if -export-dynamic
was specified and there's no dlopen(NULL) support
* mdemo/configure.in: use AC_LIBTOOL_DLOPEN
* mdemo/main.c: demonstrate lt_dlopen(0)
1999-02-15 Gary V. Vaughan <gary@gnu.org>
* demo/dlmain.c (_WIN32): The lt_symlist structure is now const,
so my original horrible temporary win32 hack no longer worked.
Here is a new horrible temporary hack to prevent helldl from SEGVing
on win32. I will fix this properly when we figure out how to do
data exports from dlls.
1999-02-14 Alexandre Oliva <oliva@dcc.unicamp.br>
* libtool.m4 (AC_CHECK_LIBM): do not set MATHLIB or AC_SUBST it,
this has a negative side-effect of causing automake to add MATHLIB
to every single Makefile. Let's use plain AC_CHECK_LIB, so that
LIBS get set, until we find a better alternative
* *demo/Makefile.am: remove $(MATHLIB)
* libltdl/configure.in: add a DESCRIPTION argument to AC_DEFINEs
where appropriate, so as to get rid of acconfig.h
* libltdl/acconfig.h: removed
1999-02-13 Thomas Tanner <tanner@gmx.de>
* *demo/Makefile.am: use $(MATHLIB)
* *demo/configure.in: use AC_CHECK_LIBM
* doc/libtool.texi: renamed file_magic_command to file_magic_cmd,
renamed archive_sym_cmds to archive_expsym_cmds
* ltconfig.in: ditto
* ltmain.in: ditto
* libltdl/ltdl.c: use lt_dlmalloc/free
* libltdl/ltdl.h: define lt_dlmalloc/free
* libtool.m4: added AC_CHECK_LIBM macro
* ltconfig.in: renamed archive_sym_cmds to archive_expsym_cmds,
added always_export_symbols, export_symbols_cmd, exclude_expsyms,
include_expsyms, removed archive_cmds for cygwin/mingw and AIX,
on Solaris store the exported symbols list in objdir
* ltmain.in: allow -export-symbols for modules, use thread_safe flag,
add include_expsyms to the exported symbols
1999-02-12 Gary V. Vaughan <gary@gnu.org>
* libltdl/ltdl.h (_LTDLL_EXTERN): libltdl is no longer linked as a
shared library, so the _declspec's were preventing the linker from
resolving symbols on win32. They have been removed now.
1999-02-12 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in: don't try to read objdir/libname.la before it is
created!
* ltmain.in: create libname.lai at link time, not at install time,
but still create it at install time if it is missing
Reported by Akim Demaille <demaille@inf.enst.fr>
* libltdl/ltdl.c (tryall_dlopen): strcmp filenames was reversed
1999-02-11 Thomas Tanner <tanner@gmx.de>
* autogen: libltdl needs autoheader
* demo/Makefile.am: renamed hell.debug to hell.static
(we're demonstrating static linking, not debugging)
* tests/demo*: ditto
* doc/libtool.texi (libltdl): documented new lt_dlopen(NULL)
feature
* libltdl/acconfig.h: required for config.h
* libltdl/configure.in: use config.h
* libltdl/ltdl.c: use config.h, support lt_dlopen(NULL)
(returns a handle for the program itself)
* ltconfig.in: minor reformatting
* ltmain.in: in lt_preloaded_symbols always define
the program's symbols first, for -export-dynamic list all
program symbols together, -export-symbols was broken for
programs, minor reformatting
* mdemo/Makefile.am: renamed mdemo.debug to mdemo.static
* tests/mdemo*: ditto, mdemo.test was completely broken
1999-02-10 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (irix5*, irix6*, osf3*, osf4*): do not use
-set_version in archive_cmds if verstring is empty
(irix6*, shlibpath_var, sys_lib_search_path-spec,
deplibs_check_method): set appropriate values depending on
selected ABI, -32, -n32 or -64, as set in LD by libtool.m4
(uts4*): remove dot between .so and versuffix
1999-02-08 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (irix5*, irix6*, deplibs_check_method): use
file_magic for inter-library dependency tracking
* ltconfig.in (irix5*, hardcode_libdir_separator): set it to a
colon, because on IRIX 5 only the last -rpath switch prevails, and
it can be a list of colon-separated directories. This change will
affect irix6 too, but that's not a problem.
* ltconfig.in (irix5*, library_names_spec): add soname_spec,
otherwise we can't dlopen
1999-02-08 Thomas Tanner <tanner@gmx.de>
* ltconfig.in: according to Marcus Sundberg <mackan@stacken.kth.se>
HP/UX, IRIX, OpenBSD, Digital Unix and SunOS support
need_version=no and need_lib_prefix=no,
fixed a bug in Solaris' archive_sym_cmds
1999-02-04 Alexandre Oliva <oliva@dcc.unicamp.br>
* libtool.m4 (ac_cv_sys_global_symbol_pipe): accept TAB in
addition to space as separator, and allow more than one space
between the symbol code and the symbol name; HP/UX's nm, for
example, uses two spaces
* ltconfig.in (global_symbol_pipe): ditto
(bsdi4, deplibs_check_method): variable name was misspelled
* libltdl/configure.in (libltdl_cv_preloaded_symbols): rewrite
test, so as not to depend on the way global_symbol_pipe is
initialized; the current test would get false positives, as
global_symbol_pipe was initialized `x=""', not `x='
* libltdl/ltdl.c (find_module): initialize filename if dir is NULL
Reported by Godmar Back <gback@cs.utah.edu>
1999-02-04 Godmar Back <gback@cs.utah.edu>
* libltdl/ltdl.c (lt_dlopenext): missing space for terminator when
allocating memory for shlib_ext
1999-02-03 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/ltdl.c (lt_dlopenext): tmp would be trashed if shlib_ext
was longer than 3 characters
1999-02-02 Gary V. Vaughan <gary@gnu.org>
* ltconfig.in: new config.guess returns *-*-cygwin now instead of
*-*-cygwin32. sed -e 's%\(cygwin\|mingw\)32%\1%g' ltconfig.in
* ltmain.in: sed -e 's%\(cygwin\|mingw\)32%\1%g' ltmain.in
* ltconfig.in (hardcode_libdir_flag_spec, allow_undefined_flag,
archive_cmds, archive_sym_cmds, old_archive_from_new_cmds):
removed duplication of config by assuming that `test $with_gcc =
yes' implies gnu ld, otherwise MSVC++ (which I haven't tested
since I inheritted the code from Ian Lance Taylor btw!) is implied.
1999-01-28 Gary V. Vaughan <gary@gnu.org>
* ltmain.in: Reverted this change of Alexandre's from the
1999-01-25; "don't try to use .o instead of .lo just because
there's no PIC flag. It loses if --disable-static, and there's
not much point if we're referring to the same file anyway...",
because not all linkers will accept .lo object names.
* ltmain.in: In the case where --disable-static is specified (as
noted in Alexandre's log entry), we just link some .o files to
prevent the original error.
Reported by Andrey Slepuhin <pooh@msu.ru>
1999-01-27 Alexandre Oliva <oliva@dcc.unicamp.br>
* libtoolize.in: search for A[MC]_PROG_LIBTOOL, not
AM_PROG_LIBTOOL
Reported by Jeff Garzik <jgarzik@pobox.com>
1999-01-27 Gary V. Vaughan <gary@gnu.org>
* THANKS: Now that we have a policy, applied it to the existing
list. This in no way demeans the work of those people removed
from the THANKS file, who are still credited in the ChangeLogs and
without who's work, libtool would not work so well on many
platforms, but serves to highlight the outstanding and continued
contribution the remaining people have made. And I quote, "We
reserve THANKS for people who have made major contributions, and
leave the credit to the others for the ChangeLog only."
* THANKS: added Sam Vilain.
* ltconfig.in ($echo): When using printf to replace echo the shell
expands %s\n to %sn. Changed to use "%s\n" (with quotes).
Reported by Sam Vilain <sam.vilain@nz.unisys.com>
1999-01-27 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/ltdl.c (find_file): fix endless loop condition
(find_module): filename allocation was off by 1
* libltdl/Makefile.am (distclean-local): renamed from
distclean-hook, that didn't work
* libltdl/ltdl.c (lt_dlopen, non-.la): find_file now returns 0 on
failure
* Makefile.am (ltconfig, ltmain.sh): some broken makes don't like
macros in targets; replace $(srcdir) with @srcdir@
* configure.in (ACINCLUDE_M4_LIST): same problem; expand $srcdir
* libltdl/Makefile.am (@TOINST@/libltdl.la): if installation is
enabled, create to-be-installed libltdl.la within @TOINST@
directory
(noinst_LTLIBRARIES): even if installation is enabled, build
convenience libltdl.la, otherwise builds of random packages may
fail if the user happens to enable installation
(distclean-hook): wipe out $(TOINST)
* libltdl/configure.in: set TOINST and LIBLIBS as appropriate;
don't set NOINSTLIBS any more
* mdemo/Makefile.am: use libltdl.la
* libltdl/ltdl.c (find_file): oops, filenamesize was miscomputed
* libltdl/ltdl.c (find_file): allocate filename dynamically
* libltdl/configure.in (AC_PROG_LIBTOOL): automake does not
recognize it and fail, better keep using AM_PROG_LIBTOOL until the
next release of automake
* demo/configure.in, cdemo/configure.in: ditto
* depdemo/configure.in, mdemo/configure.in: ditto
* libltdl/ltdl.c: make all global strings char[], not char*; check
that all calls to malloc() are properly cast
(strdup, strchr, strrchr, trim, free_vars): declare as inline
(find_module): allocate filename dynamically; support null dir
(free_vars): free dir and name only if non-null
(lt_dlopen): keep dir as NULL if not given; fix expression that
calculated the size of name; only free and name if non-null
(lt_dlopenext): allocate tmp dynamically
* configure.in (pkgdatadir): expand ${PACKAGE} at configure-time,
just like automake does
* configure.in (pkgdatadir): define pkgdatadir explicitly, and
comment that automake does not need it, but libtoolize does
* Makefile.am (aclocaldir): do not set it explicitly, automake
does already
* configure.in (TIMESTAMP): use mkstamp here too
1999-01-27 Thomas Tanner <tanner@gmx.de>
* cdemo/configure.in: renamed AM_PROG_LIBTOOL to AC_PROG_LIBTOOL
* demo/configure.in: likewise
* depdemo/configure.in: likewise
* libltdl/configure.in: likewise
* mdemo/configure.in: likewise
* libltdl/ltdl.c: in find_module() check whether libdir is defined,
tryall_dlopen(): move deallocation of an already opened handle
to lt_dlopen(), allocate the directory in lt_dlopen() dynamically,
minor cleanups, fixed memory leak (name)
* libtool.m4: renamed all AM_ macros to AC_ and added aliases for
compatibilty, updated AC_SYS_NM_PARSE (no undefined symbols,
don't count the symbols)
* ltconfig.in: added thread_safe_flag_spec (not used yet),
added generic variable for linker options "linkopts" in
all archive_cmds
* ltmain.in: added -thread-safe flag (unused)
1999-01-26 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (LTCONFIG_VERSION): damn!, adding TIMESTAMP doesn't
always work, because then different ChangeLog timestamps fail to
pass the version test. Instead of forcing both ltconfig and
ltmain.sh to be updated every time ChangeLog changes, better
revert it
* ltconfig.in (LTCONFIG_VERSION): add TIMESTAMP, remove
explicit quotes and add it to the list of variables to quote
* ltmain.in: reworded `dropped inter-library dependencies'
message, and added a warning about inter-library dependencies even
for non-module builds
1999-01-26 Gary V. Vaughan <gary@gnu.org>
* Makefile.am (install-data-hook): Don't show the if expression
that tests for gzip with a conditional error message; just do it
quietly and show the error if it fails, or the next action if it
succeeds.
* configure.in: It seems Alexandre accidentally removed the
AC_SUBST(pkgdatadir) line recently which breaks libtoolize.
Reverted that small change.
1999-01-25 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/ltdl.c (find_module): test old_name and dlname for NULL,
not len==0
* libltdl/configure.in (libltdl_cv_objdir): yes, appending the "/"
in configure.in was much simpler
* libltdl/ltdl.c (objdir): ditto
* libltdl/ltdl.c (objdir): string collation isn't portable; strcat
"/" explicitly. Or should this be moved to configure.in?
1999-01-25 Thomas Tanner <tanner@gmx.de>
* libltdl/ltdl.c: allocate the variables in lt_dlopen() dynamically
1999-01-25 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in (file_magic): use egrep instead of expr to support
more general regular expressions
(file_regex): remove it; the name is misleading, it's not used
anywhere, and probably will never be
* ltconfig.in, doc/libtool.texi: ditto
* ltconfig.in (linux-gnu*, deplibs_check_method): extend regex to
support `LSB dynamic lib' in the output of `file'
Reported by Scott D. Heavner <sdh@po.cwru.edu>
* ltmain.in (dependency_libs, xrpath): add -R switches to
dependency_libs only just before creating the .la file; they
should not be passed to the C compiler or linker at
library-creation time, since we don't know whether it is supported
* ltconfig.in (freebsd2.2*, hardcode_minus_L): for FreeBSD 2.2.6,
this must be `no'
* mkstamp: move the sed script to extract revision and date
information into a separate shell-script, so that we can break
lines between commands; FreeBSD's sed doesn't like `;' after `t'
Reported by Axel Thimm <Axel.Thimm@physik.fu-berlin.de>
* Makefile.am: use mkstamp
* THANKS: added Axel Thimm
* ltmain.in: don't try to use .o instead of .lo just because
there's no PIC flag. It loses if --disable-static, and there's
not much point if we're referring to the same file anyway...
* ltmain.in (pass_all=none, droppeddeps): set only if deplibs was
non-empty
1999-01-24 Thomas Tanner <tanner@gmx.de>
* libltdl/ltdl.c: minor bugfixes, append a "/" the search
directory only if necessary
* ltconfig.in: added support for FreeBSD >= 3.0
(patch from Kurt D. Zeilenga)
* THANKS: added Kurt D. Zeilenga
1999-01-24 Thomas Tanner <tanner@gmx.de>
* doc/libtool.texi (libltdl): list supported dlopen mechanisms,
added function lt_dlopenext(), removed reference to
LTDL_PRELOADED_SYMBOLS in LTDL_SET_PRELOADED_SYMBOLS
* libltdl/ltdl.c: partially reverted Alexandre's dynamic string
allocation change (it was not necessary and the code was unreadable),
cleanups, removed usr_search_path_size, renamed usr_search_path
to user_search_path, in find_module() also check for moved
modules, merged find_file() and find_library(),
added lt_dlopenext(), in lt_dladdsearchdir() no longer reset
the search path if 'search_dir' == NULL and don't use realloc()
(might not be available on all platforms),
removed __P((void)) in the declaration of lt_dlgetsearchpath()
* libltdl/ltdl.h: added lt_dlopenext()
* ltconfig.in: AIX archive commands were broken,
fixed a MAJOR bug in global_symbol_pipe which caused
"demo-shared.test;demo-make.test" to fail (libtool must not extract
undefined symbols of libraries, i.e. symcode must not contain 'U')
* tests/Makefile.am (clean-local): "make distclean" in cdemo, too
1999-01-22 Alexandre Oliva <oliva@dcc.unicamp.br>
* Makefile.am (ltconfig, ltmain.sh): add ChangeLog Revision to
TIMESTAMP
* configure.in: get values of PACKAGE and VERSION set by
AM_INIT_AUTOMAKE, and extract only TIMESTAMP from the ChangeLog
* libltdl/ltdl.c (lt_dlopen): if we're reusing a previously opened
handle, don't reset its name nor add it to the list, and free the
name we have allocated
Reported by Edouard G. Parmelan <Edouard.Parmelan@France.NCR.COM>
* Makefile.am (ltconfig, ltmain.sh, TIMESTAMP): let's not assume
anything about the format of the date, just that it does not
contain `$'
1999-01-22 Gary V. Vaughan <gary@gnu.org>
* configure.in (date): echo the version number during
configuration, and show $date for cvs versions.
* Makefile.am ($(srcdir)/ltconfig): Oops. cvs co keyword
expansion ate the sed expression! Changed sed separator to '%'
because there are '/' in the date. Added missing '\(' to search
expression. Inserted a null string to stop cvs from expanding it
next time =)O|
($(srcdir)/ltmain.sh): ditto.
1999-01-22 Alexandre Oliva <oliva@dcc.unicamp.br>
* Makefile.am (TSDEPS_DIST): dist-time dependencies for timestamps
(timestamps, update-timestamps): check whether TSDEPS_DIST are
up-to-date and update ltconfig and ltmain.sh if needed
(ltconfig, ltmain.sh): depend on TSDEPS; replace @TIMESTAMP@ with
the Date tag in the ChangeLog
(TSDEPS): empty unless overridden by update-timestamps
* ltconfig.in, ltmain.in (TIMESTAMP): append timestamp to most
references to VERSION
1999-01-22 Gary V. Vaughan <gary@gnu.org>
* ltmain.in (ild): Revert the change which allowed libtool to
link libraries with dependencies on .la libs.
* NEWS: Removed reference to win32, incase 1.3 ships before
ild is ready.
* doc/PLATFORMS: Removed i686-pc-cygwin32, for the same reason.
* doc/libtool.texi: Removed win32 refs, for the same reason.
1999-01-22 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in (Xsed): add 1 to Xsed definition that goes into
temporary wrapper scripts
* libtool.m4: we don't have Xsed here, expand it manually
Reported by Pavel Roskin <pavel_roskin@geocities.com>
1999-01-22 Edouard G. Parmelan <Edouard.Parmelan@France.NCR.COM>
* ltmain.in (finalize_hardcode_libdirs, finalize_rpath): in
platforms that use -rpath, programs must be finalized at
installation time, otherwise build-tree programs will
prefer installed libraries over build-tree ones
1999-01-22 Alexandre Oliva <oliva@dcc.unicamp.br>
* mdemo/Makefile.am (../libltdl/libtool): if it does not exist,
the sub-make for libltdlc.la will take care of it, but we must at
least provide an empty rule for it, otherwise the sub-make will
never run
* demo/configure.in, demo/Makefile.am (DLPREOPEN): reverted; it
didn't make any difference.
1999-01-21 Gary V. Vaughan <gary@gnu.org>
* THANKS: Added Chris Laas <golem@MIT.EDU>
From Chris Laas <golem@MIT.EDU>
* ltmain.in (compile): corrected a typo in compile mode which
caused "gcc: unrecognized option -c-fPIC" errors due to a missing
space.
1999-01-21 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/configure.in: reintroduce code to detect native library
extension
* libltdl/ltdl.c (lt_dlopen): if a .la file name is given, that's
all. Otherwise, lt_dlopen now tries to append .la first. If this
fails, it tries the given filename, and, at last, tries to append
the native library extension to the given filename.
* doc/libtool.texi (lt_dlopen): explain new lookup strategy
* libltdl/ltdl.c: major rewrite to avoid almost all fixed-size
buffers; only `tmp' in lt_dlopen remained. But the code got ugly
:-(
* ltconfig.in (linux-gnu*, finish_cmds): remove erroneous backslash
* demo/configure.in: set DLPREOPEN to -dlopen if we don't have
shared libraries
* demo/Makefile.am (DLPREOPEN): use instead of -dlpreopen
(STATIC): use $(STATIC), not @STATIC@
* mdemo/Makefile.am (STATIC): ditto
* tests/demo-shared.test, tests/demo-static.test: new tests
* tests/mdemo-shared.test, tests/mdemo-static.test: ditto
* tests/Makefile.am: ditto
* doc/libtool.texi: document them
* demo/Makefile.am, mdemo/Makefile.am (STATIC): do not use
-static unconditionally, it can't work with --disable-static
* demo/configure.in, mdemo/configure.in: check whether libtool was
configured to build static libraries and, if not, set STATIC to an
empty string
1999-01-20 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in (module, droppeddeps): if libtool could not satisfy
all dependencies of a module, it will only build a static version
of it, and display a warning message
1999-01-20 Erez Zadok <ezk@shekel.mcl.cs.columbia.edu>
* ltconfig.in (aix4*, with_gcc, archive_cmds): fix typo in Andrey
Slepuhin's last patch
1999-01-20 Alexandre Oliva <oliva@dcc.unicamp.br>
* Makefile.am (@DIST_MAKEFILE_LIST@): work around Ultrix /bin/sh bug

-bnoentry option to linker when building a shared library
1999-01-20 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in (file_magic): follow soft-links before running `file'
on the candidate library; try to avoid entering endless loop
Suggested by Nix <nix@esperi.demon.co.uk>
* ltconfig.in (linux*, solaris*, bsdi4*, sys_lib_search_path):
remove expansion of $LD_LIBRARY_PATH
* ltmain.in (lib_search_path): append the expansion of $shlibpath_var
* doc/libtool.texi: document it
* THANKS: Added Steven Schultz
1999-01-20 Steven M. Schultz <sms@wlv.iipo.gtegsc.com>
* ltconfig.in (bsdi4*, check_shared_deplibs_method): file_magic
(bsdi4*, sys_lib_search_path): add /shlib and other dirs
1999-01-20 Alexandre Oliva <oliva@dcc.unicamp.br>
* cdemo/main.c (main): use K&R definition syntax
* mdemo/main.c (test_dl, main): ditto
(test_dl): casts return value of lt_dlsym to appropriate types
* ltmain.in (dlsyms): #define const to nothing if not __STDC__
* ltconfig.in (global_symbol_pipe): #define const to nothing if
not __STDC__
* demo/dlmain.c (main): cast s->address to the appropriate pointer
types, otherwise StunOS4's cc refuses to compile it
* ltconfig.in (sunos4*, without_gnu_ld, with_gcc, archive_cmds):
add -fPIC, because libgcc is multilibbed, and we want the PIC
version of it for shared libraries, otherwise ld complains
* demo/dlmain.c (main): add missing const to declaration of name
* libltdl/ltdl.c (find_module): remove the libdir argument, and
try to open library only as old_name and dir/dlname
(lt_dlopen): use `installed' variable in .la file to decide
whether to use libdir or objdir
* demo/configure.in (AC_C_CONST): added, for portability
* mdemo/configure.in (AC_C_CONST): ditto
* libltdl/configure.in (AC_C_CONST, AC_C_INLINE): ditto
* libltdl/ltdl.c (LTDL_FILENAME_MAX): use FILENAME_MAX if defined
(FILENAME_MAX): replace all explicit uses with LTDL_FILENAME_MAX
(presym_free_symlists, trim): don't return void, for portability
(lt_dlgetsearchpath): replace (void) with __P((void))
* ltmain.in (compile): when compiling both PIC and non-PIC, write
the PIC object to .libs/.lo and only rename it to .lo after
compiling the .o, to avoid fooling make dependencies
* mdemo/main.c (LTDL_PREOPENED_SYMBOLS): remove
1999-01-20 Gary V. Vaughan <gary@gnu.org>
* TODO: Added inter-library deps for ltlibs.
* THANKS: Added Vladimir Kushnir.
1999-01-20 Vladimir Kushnir <kushn@mail.kar.net>

`file_magic_command' for freebsd-elf.
1999-01-20 Alexandre Oliva <oliva@dcc.unicamp.br>
* TODO: should we also build a `static' copy of a convenience
library out of .o files?
* ltconfig.in (bsdi4*, netbsd*, uts4*, library_names_spec,
soname_spec): removed duplicate dot before $major
Reported by Steven M. Schultz <sms@wlv.iipo.gtegsc.com> (bsdi4*)
* THANKS: added Manfred Weichel
1999-01-20 Manfred Weichel <Manfred.Weichel@pdb.siemens.de>
* ltconfig.in (sysv5*): same as sysv4.3*
1999-01-20 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/ltdl.c (lt_dlopen): properly detect error condition when
full pathname of non-libtool library is provided
* libltdl/configure.in (libltdl_cv_preloaded_symbols,
HAVE_PRELOADED_SYMBOLS): test whether we support -dl*open
* libltdl/ltdl.c (!HAVE_PRELOADED_SYMBOLS, lt_preloaded_symbols):
define it to an empty list if libtool won't generate it, so as to
avoid link errors. This will cause silent dlopening failures, but
maybe this is better than failing to link the program...
* libltdl/ltdl.h (LTDL_PRELOADED_SYMBOLS): remove it; better to
declare lt_preloaded_symbols
* doc/libtool.texi (LTDL_PRELOADED_SYMBOLS): ditto
* ltmain.in (dlpredeps): removed, reverting 1999-01-17's change
1999-01-19 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/Makefile.am (Makefile): depend on libtool
* ltmain.in (lt_preloaded_setup): function added to symbol list
source file to work around FreeBSD problem
* Makefile.am (check-local): depend on libltdl/Makefile
* mdemo/Makefile.am (mdemo_LDFLAGS, mdemo_LDADD): moved -dlopen
flags to LDADD

* ltmain.in (compile_dependencylibs): removed this
variable, use deplibs to hold these dependencies.
From Andrey Slepuhin <pooh@msu.ru>
* ltmain.in (hardcode_action) make sure deplibs is set to include
all the extra libs added to compile_command.

* libltdl/Makefile.am (libtool): use it
* doc/libtool.texi (AM_PROG_LIBTOOL): document it
* Makefile.am (libltdl.tar.gz): don't create it as part of the
build, since it is likely to become stale if we do
(install-data-hook): create and install libltdl.tar.gz, without
depending on GNU tar
Reported by Manfred Weichel <Manfred.Weichel@pdb.siemens.de>
1999-01-17 Thomas Tanner <tanner@gmx.de>
* Makefile.am: added libltdl.tar.gz to CLEANFILES
* ChangeLog: some reformatting
* TODO: documentation updates
* doc/libtool.texi: added preliminary libltdl documentation,
updated dlopen and -module documentation,
renamed -avoid-versioning to -avoid-version
documented the libtool script variables compiler_c_o,
compiler_o_lo, need_locks, old_postuninstall_cmds,
postuninstall_cmds, sys_lib_search_path_spec,
fix_srcfile_path, objdir, objext, libext,
documented the two new flags (--ltdl[-tar]) of libtoolize
* libltdl/Makefile.am: incremented the version, removed
libtool dependency so that it can be build independently
* libltdl/configure.in: removed LTDL_SHLIB_EXT hack,
set version to 1.0, use AM_MAINTAINER_MODE,
DLPREOPEN is always supported, check for libtool's objdir variable
(LTDL_OBJDIR)
* libltdl/ltdl.c: some cleanups (moved constants to the beginning
of the file and prefixed all of them with LTDL_, minor optimizations
in find_file() and find_module()), renamed lt_dlpreopen* to
lt_dlpreload* for consistency, removed LTDL_SHLIB_EXT hack,
we don't need unistd.h, DLPREOPEN is _always_ supported,
reverted Alexandre's lt_dlpreopen_default_ change,
try to open the not-installed module before the installed one,
replaced lt_dlsearchpath() with lt_dladdsearchdir(),
lt_dlsetsearchpath() and lt_dlgetsearchpath()
* libltdl/ltdl.h: renamed lt_dlpreopen* to lt_dlpreload*
for consistency, removed the declaration of lt_preloaded_symbols
(should be imported by programs),
reverted Alexandre's lt_dlpreopen_default_ change and added
two new macros LTDL_PRELOADED_SYMBOLS and
LTDL_SET_PRELOADED_SYMBOLS(),
added lt_dladdsearchdir(), lt_dlsetsearchpath() and
lt_dlgetsearchpath()
* libtool.m4: some reformatting

the libtool package directory
* ltconfig.in: removed $thread_safe_flags from Andrey Slepuhin's
AIX patch, renamed sys_lib_search_path to sys_lib_search_path_spec,
some reformatting, fixed typo in deplibs_check_method (unkwnon)

LTDL_SET_PRELOADED_SYMBOLS()
1999-01-17 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltconfig.in (wlarc): set to either '${wl}' or an empty string,
depending on whether archive_cmds runs CC or LD
(gnu_ld=yes, whole_archive_flag_spec): "$wlarc" instead of '${wl}'
* mdemo/Makefile.am (../libltdl/libltdlc.la): depend on
../libtool, because ../libltdl/libtool depends on it
(mdemo_debug_*): copy from mdemo_*, adding -static to LDFLAGS
* ltmain.in (dlpredeps): append dependencies from dlopened modules
(but not dlpreopened ones) after all explicitly linked libraries
* ltconfig.in (need_lib_prefix, need_version,
deplibs_check_method): default to unknown, so that we're
remembered that this needs porting; unknown is interpreted as yes,
yes and none, respectively
(freebsd2*, freebsd3*, sunos4*, need_version): set to yes
(freebsd2*, freebsd3*, library_names_spec): libraries without a
version number are not used by `ld'; add $versuffix;
Reported by Ben Jackson <ben@ben.com>
* ltmain.in (deplibs_check_method): alias unknown to none
(need_version): if vinfo was not provided and release info was,
zero out versuffix only if we don't need_version.
* doc/libtool.texi: document what `unknown' means
* libltdl/ltdl.h (lt_dlpreopen_default): reverted to a macro
without arguments, that calls lt_dlpreopen_default_ with
lt_dlpreloaded_symbols
* libltdl/ltdl.c (lt_dlpreopen_default_): renamed from
lt_dlpreopen_default
(find_module) tryall_dlopen old_name first, so that we don't
override statically linked symbols with dlopened ones
1999-01-15 Gary V. Vaughan <gary@gnu.org>
From Andrey Slepuhin <pooh@msu.ru>
* libtoolize.in (cd $pkgdatadir): Make sure we return the the

aix4*, and tweak the config for aix3.
* NEWS: added aix3 and aix4 to list of hosts with improved
support.
* THANKS: added Andrey Slepuhin <pooh@msu.ru>.
1999-01-15 Thomas Tanner <tanner@gmx.de>
* Makefile.am (@DIST_MAKEFILE_LIST@): added a second '$'
before abs_scrdir, removed ltconfig and ltmain.sh from
EXTRA_DIST (automake distributes them by default)
1999-01-14 Thomas Tanner <tanner@gmx.de>
* autogen: moved faking of the libtool scripts before
the call of automake, so that ltconfig and ltmain.sh
are included in the distribution
* ltconfig.in: when checking whether PIC is supported assume
only on HP/UX that warnings during compilation mean that
PIC is not supported (Thanks to Ron O'Hara)
* THANKS: added Ron O'Hara
1999-01-14 Alexandre Oliva <oliva@dcc.unicamp.br>
* Makefile.am: Moved ltconfig and ltmain.sh back into srcdir, and
add them to the distribution. Added work-around if `mv -f' fails.
fix @AINCLUDE_M4_LIST@ and @DIST_MAKEFILE_LIST@ for relative and
absolute specifications of srcdir
1999-01-14 Thomas Tanner <tanner@gmx.de>
* libltdl/ltdl.c: added variable symbol prefix, added user-defined
library search path (can be set using lt_dlsearchpath()),
added default_preloaded_symbols which are independent of
lt_dlinit/exit
* libltdl/ltdl.h: added lt_dlsearchpath() and
lt_dlpreopen_default()
* mdemo/Makefile.am: use -export-dynamic until libtool
and libltdl are able to handle module dependencies
1999-01-14 Gary V. Vaughan <gary@gnu.org>
* THANKS: added Mark Elbrecht.
* ltconfig.in (PATH_SEPARATOR): new variable to hold valid $PATH
separator characters for the build host, to support DJGPP
environment.
* ltconfig.in: Use PATH_SEPARATOR instead of hardcoded `:'.
Reported by Mark Elbrecht <snowball3@usa.net>
* cdemo/README: typo: mdemo->cdemo
1999-01-14 Thomas Tanner <tanner@gmx.de>
* autogen: fake the libtool scripts to help fixing
the bootstrapping problem
* Makefile.am: always configure libltdl, however after building
the libtool scripts,
build the libtool scripts in builddir, not srcdir
(unfortunately this breaks building when srcdir!=objdir,
but it was just plain wrong - needs to be fixed),
build and install libltdl.tar.gz,
copy acinclude.m4 instead of linking them, so that we
can 'make dist' in libltdl,
fixed configuring of subdirectories
* configure.in: removed --enable-ltdl-install - libltdl is supposed
to be installed by packages, not by libtool itself
* libtoolize.in: new flags --ltdl and --ltdl-tar to install libltdl
in packages (--ltdl doesn't work yet),
install only the necessary libtool scripts, not just all
files in pkgdatadir
* mdemo/Makefile.am: removed the rule for libltdl configuration
1999-01-13 Alexandre Oliva <oliva@dcc.unicamp.br>
* mdemo/Makefile.am (../libltdl/libtool): mkdir and configure
../libltdl
1999-01-13 Thomas Tanner <tanner@gmx.de>
* demo/dlmain.c, libltdl/ltdl.c, ltconfig.in, ltmain.in,
doc/libtool.texi: renamed dld_preloaded_symbols to
lt_preloaded_symbols, symbol lists are 'const'
* cdemo/configure.in: don't check for string.h
* demo/dlmain.c: renamed dld_symlist to lt_symlist,
preloaded symbols are 'const', use lt_ptr_t instead of void*
* demo/foo.h: define lt_ptr_t
* doc/libtool.texi: document lt_preloaded_symbols correctly
* libltdl/Makefile.am, mdemo/Makefile.am: renamed libtest to libltdlc
* libltdl/ltdl.c: fixed some minor typos, renamed dldpre to presym,
bugfix: search in search_path only if we have no directory
and a search_path, in lt_dlsym() check whether symbol != 0
* libltdl/ltdl.h: removed lt_dlpreopen_default()
* ltconfig.in (dlpreopen): removed dld_preloaded_symbol_count
* ltmain.in: added help for -avoid-versioning, -export-symbols,
-module, add @SYMFILE@ if one of -export-dynamic, -dlopen or
-dlpreopen is used
* mail/deplibs.html: added Gordon Matzigkeit's inter-library
dependencies article
* mdemo/Makefile.am: removed -export-dynamic from LDFLAGS
(no longer necessary, since libtool defines lt_preloaded_symbols
when -dlopen is used), initialize with lt_preloaded_symbols
1999-01-13 Alexandre Oliva <oliva@dcc.unicamp.br>
* doc/libtool.texi (Test descriptions): cdemo-static works, thanks
to Edouard Parmelan!
* THANKS: added Sebastian Wilhelmi
* ltconfig.in (solaris): define `need_version' to no
1999-01-13 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* ltconfig.in (solaris): Define `deplibs_check_method',
`file_magic_command', `need_lib_prefix' and `sys_lib_search_path'
* ltmain.in (file_magic_regex): Add space before matching pattern,
such that it works on solaris (solaris has a tab between the
library name (including the colon) and the `ELF' and such the
`ELF' will never be matched).
1999-01-13 Edouard G. Parmelan <Edouard.Parmelan@France.NCR.COM>
* ltconfig.in (NM): PATH search was not updated like in
libtool.m4, in last Alexandre Oliva's change to it
(sysv4*, ncr): pass all library dependencies
* ltmain.in (dependency_libs, -R): use `deplib' instead of `arg' to
iterate, otherwise we'd overwrite `arg'
(convenience, old_libs): if --disable-shared, convenience
libraries are just old archives, as .lo's are of no use
* tests/cdemo-static.test: print --disable-shared here
1999-01-13 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/configure.in (libltdl_cv_shlibext, LTDL_SHLIB_EXT):
system-dependent extension of shared libraries
(libltdl_cv_shlibpath_var, LTDL_SHLIBPATH_VAR): system-dependent
run-time shared library search path
* libltdl/ltdl.c (dldpre_init, dldpre_exit): unrelate init/exit
from add/remove symlists, so one may add dld_preloaded_symbols
from main(), when only a library will call dldpre_init
(lt_dlopen): use LTDL_SHLIBPATH_VAR, if defined, as secondary
search path. Also, if a requested .la file cannot be found, try
with the LTDL_SHLIB_EXTension instead.
* ltmain.in (old_archives, oldobjs): use find to SYMDEF here too
* Makefile.am (@DIST_MAKEFILE_LIST@): `$' must be doubled
* configure.in (AC_CONFIG_DIRS): configure only libltdl, and then,
only if --enable-ltdl-install
(CONF_SUBDIRS): list directories that are configured on demand,
but that must be included in the distribution
(ACINCLUDE_M4_LIST, DIST_MAKEFILE_LIST): generated from CONF_SUBDIRS
* Makefile.am (AUTOMAKE_OPTIONS): added version 1.3e and
readme-alpha, to handle README-alpha automatically
(EXTRA_DIST): removed README-alpha
(BUILD_SUBDIRS): subdirectories that are always built
(SUBDIRS): BUILD_SUBDIRS plus BUILD_LTDL
(DIST_SUBDIRS): BUILD_SUBDIRS plus CONF_SUBDIRS, from configure
(all-local, check-local): depend on $(ACINCLUDE_M4_LIST), from
configure, and libtool, so that it is built before subdirs
(configure-subdirs): new target
(configure-subdirs, distdir): depend on $(DIST_MAKEFILE_LIST),
from configure
(@DIST_MAKEFILE_LIST@): create subdir if needed, then run
configure.
On-demand configuration of subdirs at distribution time was
suggested by Gary V. Vaughan <gary@gnu.org>
* libtool.m4, ltconfig.in (NM): search for NM in PATH before
/usr/ccs/bin, /usr/ucb and /bin. However, if the found one isn't
BSD-compat keep searching. If no BSD-compat is found, use the
first we found.
* THANKS: added Raffaele Sena
1999-01-13 Raffaele Sena <raff@aromatic.com>
* libltdl/ltdl.c: replaced RTDL with RTLD
1999-01-13 Manish Singh <yosh@gimp.org>
* ltconfig.in (osf3*, osf4*, irix6*): include
${libname}{release}.so for library_names_spec
1999-01-13 Alexandre Oliva <oliva@dcc.unicamp.br>
* configure.in (AC_CONFIG_SUBDIRS): added cdemo
* Makefile.am (DIST_SUBDIRS): ditto
(ACINCLUDE_M4_LIST): ditto
* tests/Makefile.am (TESTS): added cdemo-shared.test
* tests/cdemo-static.test: disable shared libraries here
* tests/cdemo-shared.test: disable static libraries here
* doc/libtool.texi (Test descriptions): added cdemo tests
* THANKS: added Edouard G. Parmelan
1999-01-13 Edouard G. Parmelan <Edouard.Parmelan@France.NCR.COM>
* ltmain.in: fix convenience libraries when static libraries
are disables.
* cdemo/README, cdemo/Makefile.am, cdemo/configure.in, cdemo/foo.h,
cdemo/foo1.c, cdemo/main.c, cdemo/.cvsignore, test/cdemo-conf.test,
test/cdemo-make.test, test/cdemo-exec.test, test/cdemo-static.test:
new tests for convenience libraries.
* autogen, Makefile.am, test/Makefile.am: ditto.
* ltconfig.in, doc/PLATFORMS: Added support for NCR MP-RAS
(i586-ncr-sysv4.3*) with native compiler.
* README, doc/libtool.texi: Added note for NCR MP-RAS compiler.
1999-01-12 Thomas Tanner <tanner@gmx.de>
* ltmain.in: before using LN_S remove the symlink
* libltdl/ltdl.c: support multiple symbol lists, moved library-
and file searching to separate functions, renamed "preload_libs"
to "dl_dependency_libs", set the LT_SYMBOL_OVERHEAD to the correct
value (7), fix to support lt_dlsym() for not-libtool modules again,
check for invalid handles, when using strdup() check whether
it fails
* libltdl/ltdl.h: declare the lt_dlsymlist type for lt_dlpreopen()
* mdemo/README: rewritten
* mdemo/configure.in: check only for math.h (string.h is no longer
necessary)
1999-01-12 Gary V. Vaughan <gary@gnu.org>
* configure.in (ltdl-install): Fixed up the indentation so that
`configure --help' is pretty again.
1999-01-11 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in, NEWS, doc/libtool.texi: Added support for -R flag
* ltmain.in, doc/libtool.texi: documented that -rpath is the same
as -R for programs
* ltmain.in: softened the instructions for linking with installed
libraries, and noted that libtool can be used to link with them;
documented that -rpath is not required for convenience libraries
* ltconfig.in (symxfrm): don't print $pipe_works twice, once for
each $ac_symprfx
Reported by Godmar Back <gback@cs.utah.edu>
* ltmain.in (convenience, libobjs): get only .o and .lo files from
the files extract from the convenience library. Some systems,
such as FreeBSD2, will add a SYMDEF file, that is not an object
file, and therefore should not be fed to the linker
* libtool.m4 (AM_SYS_NM_PARSE): while we are at it, we may well
cache the value of ac_cv_sys_symbol_underscore
* libtool.m4 (AM_SYS_NM_PARSE): need for underscore prefix is now
auto-detected, by trying first without, then with it.
* ltconfig.in: ditto
1999-01-10 Alexandre Oliva <oliva@dcc.unicamp.br>
* configure.in (AC_CONFIG_SUBDIRS): add libltdl, demo, mdemo and
depdemo commented out, so that `dist' works before `check'
(BUILD_LTDL): will contain libltdl if --enable-ltdl-install
* Makefile.am (DIST_SUBDIRS): expand SUBDIRS and add depdemo,
commented out
(SUBDIRS): add $(BUILT_LTDL)
* libltdl/Makefile.am (EXTRA_LTLIBRARIES): add libtest.la, the
same as libltdl but always a convenience library. Not built by
default. Both libraries now depend on the libtool script, that
depends on ../libtool and is rebuilt when needed
* mdemo/Makefile.am (mdemo, mdemo.debug): depend on and link with
../libltdl/libtest.la, that is rebuilt if needed
(mdemo_LDADD): removed $(LIBADD_M), to avoid silent failures
(foo1.la): renamed from libfoo1.la; test removing the lib prefix
* mdemo/foo1.c: renamed libfoo1_LTX symbols to foo1_LTX
* mdemo/main.c: don't include string.h nor math.h, nor refer to
sin nor cos
* tests/mdemo-exec.test: renamed libfoo1.la to foo1.la
* tests/mdemo-inst.test: ditto
* libltdl/ltdl.c (FILENAME_MAX): use it instead of MAX_FILENAME,
and don't redefine it if already defined; default to 1024, as on
most systems
(LT_SYMBOL_LENGTH): renamed from MAX_SYMBOL_LENGTH
(LT_SYMBOL_OVERHEAD): new macro, that accounts for the size of
the _LTX_ separator and the initial underscore
(lt_dlsym): sym now points to a stack buffer (lsym) if possible,
or is dynamically allocated. If allocation fails, a
buffer_overflow_error is returned.
1999-01-10 Thomas Tanner <tanner@gmx.de>
* ltmain.in: define dld_preloaded_symbols if at least one of
-export-dynamic, -dlopen or -dlpreopen was specified,
do not include program objects in the symbol list
if -export-dynamic was not enabled
* libltdl/ltdl.c: limit symbols to max. 256 bytes
* mdemo/Makefile.am: build libltdl in a subdirectory,
do not use -export-dynamic for mdemo and mdemo.debug
* tests/mdemo-conf.test,tests/mdemo-make.test,tests/mdemo-inst.test:
do not check for libltdl
1999-01-09 Alexandre Oliva <oliva@dcc.unicamp.br>
* libltdl/ltdl.c (lt_dlopen): missing strlen in bound test
1999-01-09 Thomas Tanner <tanner@gmx.de>
* NEWS: support for BSD/OS 4.x was not documented
* demo/Makefile.am: link against libm only if available
* mdemo/Makefile.am: likewise, use -avoid-versioning flag
instead of -avoid-version (typo)
* demo/configure.in: check for libm, string.h and math.h
* mdemo/configure.in: likewise
* depdemo/configure.in: check for libm and math.h
* libltdl/configure.in: check for dlerror
* libltdl/ltdl.c: check for buffer overflows, implemented
dlerror, fixed a severe bug which occured when opening
non-libtool modules, dlopen with the flags GLOBAL and NOW
* mdemo/main.c: report the error using lt_dlerror()
1999-01-08 Gary V. Vaughan <gary@gnu.org>
* doc/libtool.texi (old_archive_from_new_commands): Documented
this ltcofig variable.
1999-01-07 Gary V. Vaughan <gary@gnu.org>
* ltmain.sh (cygwin, allow_undefined): Unfortunately, there are
problems with this variable when trying to make a dll which has
undefined symbols, in which case not even a static library is
built. For now, we need to specify -no-undefined on the libtool
link line when we can be certain that all symbols are satisfied,
otherwise we get a static library.
1999-01-06 Thomas Tanner <tanner@gmx.de>
* ChangeLog: merged in tests/ChangeLog
* tests/ChangeLog: deleted
* libltdl/ltdl.c: assigned copyright to the FSF
* libltdl/ltdl.h, mdemo/foo*,main.c: likewise
1999-01-06 Gary V. Vaughan <gary@gnu.org>
* ltmain.in (dllsearchpath): add absolute directory paths to
dllsearchpath so that the wrapper scripts can be called from any
directory (e.g. tests) on cygwin.
* ltconfig.in (cygwin, library_names_spec): revert Alexandre's
change from yesterday to use `-dll.a' suffix. That change caused
$libname-dll.a to be a symlink to $soname, which isn't even an
`ar' archive. Before the import library suffix can be changed, we
need to figure out how to handle building objects differently for
linking with an import library versus an equivalent static library.
* TODO: Added details of a Linux wrapper script bug.
Reported by Jeff Garzik <jgarzik@pobox.com>.
1999-01-05 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in (libobjs_save, oldobjs): when building an
old-fashioned archive, use a copy of libobjs saved before
convenience libraries are appended
* libltdl/ltdl.h (_LTDLL_EXPORT, _LTDLL_IMPORT): use cygwin or
unix library import/export primitives; this may be convenient for
people willing to create DLLs
(_LTDLL_EXTERN): select _LTDLL_EXPORT or _LTDLL_IMPORT depending
on _LTDL_COMPILE_
* libltdl/ltdl.h, libltdl/ltdl.c (lt_dlpreopen): new function,
that replaces the current preloaded_symbols list with its
argument, and returns the old value, initially NULL
(dldpre_init): don't refer to dld_preloaded_symbols any more
(dldpre_open, dldpre_sym): search preloaded_symbols
(lt_dlpreopen_default): call lt_dlpreopen with
dld_preloaded_symbols, that is declared as extern; it should be
called from the main program or from some static library without
-no-undefined
(lt_dlerror): new function, that returns the error message for the
last error occurred; the error message is kept in the static
variable last_error
* libltdl/configure.in (enable-ltdl-install): moved back from
enable-install; other packages might use enable-install already,
better have fine grained control over this.
* libltdl/Makefile.am (libltdls.la): discarded
1999-01-05 Thomas Tanner <tanner@gmx.de>
* configure.in: do not configure libltdl by default
* Makefile.am: do not build libltdl by default
* libltdl/Makefile.am: ltdls.lo depends on libtool
* tests/Makefile.am: before starting the tests
make sure that libtool was build
* tests/mdemo-conf.test: configure libltdl
* tests/mdemo-make.test: build libltdl
1999-01-05 Alexandre Oliva <oliva@dcc.unicamp.br>
* ltmain.in (SP2NL, NL2SP): Don't delete empty lines, as this
would lose for files with embedded blanks.
* ltconfig.in (cygwin, archive_cmds, archive_sym_cmds): Moved
ltdll.c into ltmain.in, to avoid its duplication, and added a sed
script to extract it. Also, create def and base files in $objdir,
and don't remove them after the compilation.
(cygwin, library_names_spec): Create static part of the dll with
suffix -dll.a, to avoid conflicts with actual static libraries.
* ltmain.in: Added ltdll.c, as commented out text
1999-01-01 Thomas Tanner <tanner@gmx.de>
* NEWS: new BeOS support
* THANKS: added Joseph Beckenbach
* libltdl/ltdl.h: use dllimport/export on Win32
