* 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.
when dlopening the executable
* libtool.m4 (AC_LIBTOOL_DLOPEN): removed the redundant "yes: "
prefix for lt_cv_dlopen, renamed lt_cv_dlopen_LIBS
to lt_cv_dlopen_libs (more consistent)
* ltmain.in: implemented -dl[pre]open self, necessary for
lt_dlopen(NULL), generation of exported symbols was broken
trying in dl. Add the actual dlopening type to lt_cv_dlopen, and
add any needed libraries to lt_cv_dlopen_LIBS. Add test for
MS-Windows' LoadLibrary. Check whether a program can dlopen
itself only if we really have dlopen(), not some equivalent
function, but leave room for testing with other mechanisms.
(AC_PROG_LIBTOOL): assume some form of dlopen, but not
dlopen(NULL), is available if AC_LIBTOOL_DLOPEN is not used, for
backward compatibility.
* 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)
this has a negative side-effect of causing automake to add MATHLIB
to every single Makefile. Let's use plain AC_CHECK_LIB, so that
LIBS get set, until we find a better alternative
* *demo/Makefile.am: remove $(MATHLIB)
* *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
* libltdl/ltdl.c: use lt_dlmalloc/free
* 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
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='
* 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)
* 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.
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
