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.
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...),
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
* 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
* 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.
will be used as an argument for $file_magic_cmd to test whether
the regex in deplibs_check_method matches its output
(file_magic_cmd): use full pathnames whenever possible
lists the system *run-time* search path. Listed directories are
not implicitly hard-coded into executables.
* ltmain.in: use it, but *never* discard -R flags
* doc/libtool.texi: document it
* NEWS: ditto
Reported by Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
output of NM too
(global_symbol_to_cdecl): new variable; convert the output of
global_symbol_pipe to valid C declarations; on HP/UX, convert
text symbols to function declarations
* libtool.m4: similar modifications
* doc/libtool.texi: document new variable
* ltmain.in: use global_symbol_to_cdecl to generate lt_dlpreopened
symbols; avoid extracting symbol lists from dlpreopened files
twice; do not filter symbols from dlpreopened libraries
* TODO: fixed HP/UX dlpreopening problem
(AC_LIBTOOL_SETUP): if lt_dlopen=yes, add --enable-dlopen to
libtool_flags; drop --enable-dlopen-self
* ltconfig.in: perform all the dirty work of testing for dlopening
support, because we need platform-dependent equivalents for
-export-dynamic, for self dlopening, and -static, for static self
dlopening
(dlopen_self_static): new configuration variable that is set to
yes only if static programs can dlopen themselves
* ltmain.in (-static, -all-static): dlopen_self=dlopen_self_static
configure-work that AC_PROG_LIBTOOL used to do; add
--cache-file=$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
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.
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
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.
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.
* autogen: only libltdl needs autoheader
* doc/libtool.texi (link mode): documented -export-symbols-regex
and updated -export-symbols

always_export_symbols, export_symbols_cmd, exclude_expsyms,
include_expsyms, dlopen and dlopen_self
more detailed description of need_lib_prefix

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
* ltconfig.in: ditto
* ltmain.in: ditto

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/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
-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
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.
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='
*-*-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.
* 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>
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
(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
1999-01-20 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
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
