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
(cvs-diff): ditto
(EXTRA_DIST): added README-alpha
(DIST_SUBDIRS): added depdemo
* README-alpha: minor adaptations
* demo/Makefile.am, mdemo/Makefile.am, depdemo/Makefile.am:
removed comment about special needs for distribution
* depdemo/Makefile.am: don't generate dependencies
* depdemo/configure.in: modified version number
* libltdl/Makefile.am (CFLAGS): ditto
* libltdl/configure.in: check for memory.h, rindex() and
dlpreopening. Fixed NEED_USCORE caching policy.
* libltdl/ltdl.h (lt_dlsym): make the name argument const
* libltdl/ltdl.c (types): new variable: head of list of available
dlopening mechanisms
(lt_dltype_t): interface of a dlopening mechanism, with pointers
to functions for init, exit, open, close and sym
(lt_dlhandle_t): added pointer to interface type
(strdup): don't name it strdup; it can be troublesome
(strrchr): ditto; use rindex if available
(LIBTOOL_STATIC): check HAVE_DLPREOPEN instead, and move to the
end of the file, so that it becomes the header of the list
(all): renamed all interface-implementation functions, to avoid
name clashes, and created lt_dltype_t nodes for all of them
(lt_dlinit): initialize all available interfaces; remove those
that fail from the list. Return failure only if no interfaces
could be initialized.
(lt_dlexit): return number of failures
(tryall_dlopen): try to open the library with all available
interfaces
(lt_dlopen): use tryall_dlopen; increased size of fixed buffers.
We should probably make these bound-checked or dynamically
allocated for the final release! Fix bug when filename did not
contain slashes; should we check for `\\' too? Try old_library if
everything else fails.
(lt_dlclose): use the interface type for closing
(lt_dlsym): make `symbol' const, use interface type for looking up
* mdemo/Makefile.am: moved mdemo/modules/* back into mdemo
(SUBDIRS): removed
(libfoo2_la_LDFLAGS): added -static; nice test. However, since it
causes -lm to linked into hell*, it causes tests that should fail
to pass
(noinst_HEADERS): no need to install foo.h
* mdemo/configure.in: remove modules/Makefile
tests/mdemo-exec.test: updated accordingly
maintainers. Detailed expected failures of libtldl+mdemo. Listed
recent ports. Added full URL for the home page. Note that
libtool C program is unusable.
* Makefile.am (SUBDIRS): build libltdl by default
(DIST_SUBDIRS): simplify distribution of demo and mdemo
(libtool, clibtool, libtoolize, ltconfig, ltmain.sh): add
srcdir where appropriate
(ACINCLUDE_M4_LIST): new rule for maintaining links from
acinclude.m4 to libtool.m4
(*demo/Makefile.in): don't update autoconf/automake files any
more; make check is needed
(Dlopen issues): added reference to libltdl, still undocumented
(C++ libraries): it's not *that* simple, after all :-(
(Inter-library dependencies): they're back!
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
* 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
