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...
* 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
* 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)
* *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

* 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
* 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
*-*-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.
1999-01-25; "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>
* 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)
more general regular expressions
(file_regex): remove it; the name is misleading, it's not used
* 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>
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
(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
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.
platforms that use -rpath, programs must be finalized at
installation time, otherwise build-tree programs will
prefer installed libraries over build-tree ones
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.
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
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).
libtool.m4, in last Alexandre Oliva's change to it
(sysv4*, ncr): pass all library dependencies
* ltmain.in (dependency_libs, -R): use `dep' 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
* 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
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
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
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
* mdemo/Makefile.am: ../libltdl is within $(srcdir)
* libltdl, Makefile.am: added libltdl (a system independent
dlopen wrapper library extracted from mdemo)
* ltmain.in: added -module flag for compiling and linking of
modules. If enabled it compiles always both .o (with -DLT_RENAME)
and .lo files
* mdemo: modified mdemo to work with libltdl
* tests/ltdl*: added tests for libltdl
command-line compiler, so that we can use it to compile C sources
generated during the build. This fixes the problem that showed up
with -export-dynamic of C++ programs in egcs 1.1.
* NEWS: ditto
old_archive_from_new_cmds, old_archive_cmds, archive_cmds,
old_postinstall_cmds, postinstall_cmds, old_postuninstall_cmds,
postuninstall_cmds and finish_cmds, so that the semi-colons inside
if/then/else/fi and for/do/done etc. do not break the eval loop in
ltmain.in (below).
* ltmain.in: changed all of the eval loops to use an IFS of `~',
to allow differentiation between the end-of-statement-;
(now `~' is used) and end-of-substatement-; (still `;'). This
fixes AIX and win32 at least.
fails. The tests now check the behavior of $echo for very large
strings, because some echo commands would just core dump (e.g.,
Solaris' printf). If too large strings fail, smaller ones are
tested.
(ltecho): arrange that, if the --fallback-echo method is selected,
echo will be defined in the libtool script so as to re-run itself,
not ltconfig
* ltmain.in: add --fallback-echo
(qecho) ensure that, if --falback-echo is being used, qecho is
defined with the full pathname of the libtool script
* ltconfig.in, ltmain.in: updated and fixed the patches below
1998-11-04 Thomas Tanner <tanner@gmx.de>
* mdemo/*: added new demo to demonstrate building of dlopenend
modules
* tests/Makefile.am, tests/mdemo*: added some tests for mdemo
1998-11-04 Gary V. Vaughan <gvaughan@oranda.demon.co.uk>
* demo/configure.in: added AC_EXEEXT macro so that the tests can
work on cywin32/mingw32 hosts. This requires the current CVS
autoconf
1998-11-04 Thomas Tanner <tanner@gmx.de>
* ltmain.in: New flag -export-symbols; new dlpreopen system
* demo/dlmain.c: removed dld_preloaded_symbol_count
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltmain.in: On installation, don't get confused if the same name
appears more than once in the list of library names.
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltconfig.in: Add objext and libext variables. Check for object
suffix. Check for mingw32* as well as cygwin32*. Use objext when
testing compiler. Add support for Visual C++ on cygwin32 when not
using gcc. Add objext, libext, and fix_srcfile_path to generated
libtool script.
* ltmain.in: Use .${objext} rather than .o. Use fix_srcfile_path
if it is set. Check for .obj as well as for .o, and for .lib as
well as for .a. Use .${libext} rather than .a when creating old
libraries.
* libtoolize.in: Change initial /bin/sh to @SHELL@.
* libtool.m4 (AM_PROG_LIBTOOL): Add AC_REQUIRE for
AC_CANONICAL_BUILD, so that autoconf doesn't get mixed up by the
AC_REQUIRE in AC_CHECK_TOOL.
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltconfig.in: Look in the right directory for libtool.c in
archive_cmds for cygwin32.
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltconfig.in: Fix cygwin32 support to avoid using a double
extension, to delete the def file, to set version_type to windows,
and to include versuffix in the DLL name.
* ltmain.in: Add support for a version_type of windows.
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
* ltconfig.in: Add cygwin32 support.
* libtool.m4 (AM_PROG_LIBTOOL): Call AM_SYS_LIBTOOL_CYGWIN32 on a
cygwin32 host. Pass DLLTOOL and AS to ltconfig.
(AM_SYS_LIBTOOL_CYGWIN32): New macro.
available, fallback to not so safe mechanism, by setting
need_locks to warn
* ltmain.in (need_locks): when need_locks is set to warn, use the
lockfile to try to fail in case of incorrect concurrent builds
supported.
* libtool.m4 (libtool-lock): new ARG_ENABLE; sets (need_locks)
* ltconfig.in (disable-lock): control need_locks
(hard_links): check whether hard-links can be used for locking
* ltmain.in (need_locks): use $output_obj.lock for locking
components
* ltconfig.in (compiler): detect if the compiler supports
-c and -o flags, create a variable compiler_c_o. Also issue
a big warning if it is not supported
* ltmain.in (compile): enable the -o option as input for libtool.
The objects are not moved if the compiler supports -o with -c.
Sources and objects can contain relative directories.
(link): enable the linking of executables into relative directories
