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.

* 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.

--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

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

(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
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
got access to
* THANKS: added Chris P. Ross
* ltconfig.in: added recognition of the dynamic linker on BSD/OS 4.x
* README: added BSD/OS 4.x to the list of supported platforms
* doc/PLATFORMS: added BSD/OS 4.x support for various host id's
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
