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.
(cygwin, export_symbols_cmds): Ditto.
* ltmain.in: Generate export symbol list before expanding
convenience libraries, to avoid passing whole_archive_flag_spec to
$NM.
Reported by Godmar Back <gback@cs.utah.edu>
libraries with GNU ld 2.8.*, it's broken. Emit a warning
suggesting an upgrade.
Reported by Brian Ford <ford@vss.fsi.com> and Ronald Pijnacker
<Ronald.Pijnacker@best.ms.philips.com>
* ltconfig.in: set deplibs_check_method=pass_all on FreeBSD,
Linux and Solaris since no one can reproduce the famous deplibs
bug
* ltmain.in: preserve $CC (reported by Tom Tromey),
strip libraries using GNU strip if it's available and the
-s flag was passed to "install"
* TODO: -Wc, -Wl, implemented
* AUTHORS: changed my email address
* doc/libtool.texi: fix "wierd" typo :)
* ltmain.in: linking against convenience libraries was broken,
implemented the "-Wc," "-Wl," "-Xcompiler" "-Xlinker" flag for
compiler and linker-specific flags,
add -lc before we do the deplibs check
* ltconfig.in: linkopts -> compiler_flags for $CC and linker_flags
for $LD, link_all_deplibs=yes on IRIX
* NEWS: insert todays date alongside 1.3.1 release.
* Makefile.in: use gnu not gnits rules
* config.guess: synch with gnu common & apply Takabatake-san's
MIPS *000 patch.
* config.sub: synch with gnu common.
(install-data-hook): use libltdl/Makefile.am's local-install files
rule.
* libltdl/Makefile.am (local-install-files): New rule to install
libltdl without creating links or mode 777 directories.
* instutil/*: deleted.
* TODO: Recommend libtool.m4 to be inserted in acinclude.m4. AIX
4.3.2.0 no longer fails on static dlopening. GNU DLD no longer
has to support .la files, since libltdl already does. Convenience
libraries and reloadable objects should be tested in the
testsuite. We could support some amount of control on the soname
of libraries.
* doc/libtool.texi: Notes about convenience libraries and
automake. Documented INCLTDL.
* cdemo/main.c: "Welcome _to_ ..."
* mdemo/main.c: ditto
* libltdl/configure.in: support multiple dlopening mechanisms
at once
* libltdl/ltdl.c: prefix system dependent functions with "sys_"
to avoid symbol conflicts (libdld didn't work)
* libtool.m4 (AC_LIBLTDL_*): set INCLTDL to the path of ltdl.h
* ltconfig.in: check for dlopen with -ldl first
installing libltdl's sources.
* instutil/ln: New script to avoid hard-linking libltdl's sources
in the install tree.
* Makefile.am (EXTRA_DIST): Dist them.
(instal-data-hook): Add srcdir/instutil to the beginning of the
PATH before installing libltdl's sources.
* libltdl/configure.in: Clean up some duplicate defines. Enable
support for multiple dlopening mechanisms.
* libltdl/acconfig.h: New file. Add #undefs for defines that
would be duplicated.
ltconfig if this is set.
(AC_LIBTOOL_WIN32_DLL): New macro required for libtool to attempt
a dll build on win32 hosts.
* ltconfig.in (--enable-win32-dll): new flag for the cli.
(cygwin*|mingw*|os2*, ltconfig_enable_win32_dll): if this is not set
to yes, then do not attempt to build shared libraries.
* doc/libtool.texi: document AC_LIBTOOL_WIN32_DLL.
* NEWS: noted new macro.
AC_ENABLE_STATIC, AC_ENABLE_FAST_INSTALL, AC_LIBLTDL_CONVENIENCE,
AC_LIBLTDL_INSTALLABLE): Warn if they appear after
AC_PROG_LIBTOOL. AC_LIBTOOL_SETUP, actually.
(AC_LIBTOOL_SETUP): Check whether DLOPEN support is to be enabled
at autoconf time, not configure time. Simplify code and
improve (?) help message about --disable-libtool-lock.
* THANKS: added Ossama Othman
* doc/libtool.texi: documented the new `clean' mode
* ltconfig.in: set need_version=no on OSF (reported by
Marcus Sundberg <mackan@stacken.kth.se>)
* ltmain.in: allow absolute non-existant -L paths,
always use output_objdir instead of objdir for temporary files,
delete generated temporary symbol lists,
don't add .la twice in the pseudo-library header,
implemented and documented clean mode (deletes libraries,
programs and object files and the files associated with them),
if build_libtool_libs=no and no static library is available,
try to link the program against the shared library,
don't add a statically linked library to the dependency_libs
* ltmain.in (help uninstall): added a missing backslash
after echo (reported by Ossama Othman)
which links to object files we must create. Do not test for empty
pic_flag to create such links. Use objext when searching for
object files extracted from convenience library.
* ltconfig.in (cygwin*, file_magic_cmd): Use autoconf-located target
objdump tool. Track OBJDUMP like DLLTOOL and AS.
* ltconfig.in (cygwin*, deplibs_check_method): Accept
"architecture: i386" as optional suffix, for it is printed on a
separate line sometimes.
* ltmain.in (cygwin*, ltdll.c): Wrap DllMain declaration in extern "C".
* ltmain.in (deplibs_check_method=file_magic): Redirect stderr to
/dev/null, to suppress error messages from target objdump.
(aix4*, shared_flag): Set to -shared or ${wl}-bM:SRE.
(aix4*, archive_cmds): Use -bexpall.
(aix4*, archive_cmds, archive_expsym_cmds): Use shared_flag and
allow_undefined_flag.
(aix4*, always_export_symbols): Set to yes up to AIX 4.1.*,
because -bexpall is supported from 4.2 on.
Reported by Greg Wooledge
<ic5035%tss1crs.amgreetings.com@rose.amgreetings.com>
default, but set to yes by -static and -all-static. Used instead
of build_libtool_libs to decide whether to use a shared or static
version of a library, when both versions are available.
* libltdl/ltdl.c (shl_close, shl_sym): use (shl_t *) instead of shl_t
* ltconfig.in (check for gcc): removed a bogus line,
check for shl_load in libdld
* ltmain.in: added a warning to the header of the .la file
to warn users against deleting the file,
link shared against static libraries if
deplibs_check_method == pass_all
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>
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.
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 $objdir, instead
of creating it in ../tests.
* tests/Makefile.am (CLEANFILES): Removed.
automake may use sub-makes, and the setting will not be propagated
to them on some makes. Instead, create a dry version of libtool
and switch between it and the original one before and after dry
runs.
* tests/Makefile.am (CLEANFILES): Added libtool-*, created by
dryrun.test.
(before, after): Create them within ../tests.
(libtool): Set to `/bin/sh ./libtool' by default, but use LIBTOOL,
SHELL and top_builddir from the environment if available. For dry
runs, use "$libtool -n".
* tests/Makefile.am (CLEANFILES): Added before and after.
* ltmain.in: Do not create links to object files in dry runs.
* 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
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.
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
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
* 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,
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
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
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.
* 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)
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
$$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
* 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)
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
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
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.
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
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
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)
renamed convenience libltdl, dropped toinst hack for installable
* libltdl/Makefile.am: ditto
* libltdl/configure.in: ditto; abort if none of the macros is used
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@
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
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
* 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
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.
