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
* 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...),
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.
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
* 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
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
* TODO: comments on hardcoding paths into libraries; problem
with shell meta-characters in filenames
* 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,
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
* 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
* 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
* 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)
* 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.
* doc/libltdl.texi (linking with installed libtool libraries):
fixed typo
* doc/libltdl.texi (libltdl): added documentation for building
libtool modules and examples how to embed libltdl
* ltmain.in: don't ignore user-specified run-paths (fixed it
at the right place)
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>
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
(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
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
* 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
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
* 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
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.
