HAVE_PRELOADED_SYMBOLS): test whether we support -dl*open
* libltdl/ltdl.c (!HAVE_PRELOADED_SYMBOLS, lt_preloaded_symbols):
define it to an empty list if libtool won't generate it, so as to
avoid link errors. This will cause silent dlopening failures, but
maybe this is better than failing to link the program...
build, since it is likely to become stale if we do
(install-data-hook): create and install libltdl.tar.gz, without
depending on GNU tar
Reported by Manfred Weichel <Manfred.Weichel@pdb.siemens.de>
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
without arguments, that calls lt_dlpreopen_default_ with
lt_dlpreloaded_symbols
* libltdl/ltdl.c (lt_dlpreopen_default_): renamed from
lt_dlpreopen_default
add them to the distribution. Added work-around if `mv -f' fails.
fix @AINCLUDE_M4_LIST@ and @DIST_MAKEFILE_LIST@ for relative and
absolute specifications of srcdir
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
system-dependent extension of shared libraries
(libltdl_cv_shlibpath_var, LTDL_SHLIBPATH_VAR): system-dependent
run-time shared library search path
* libltdl/ltdl.c (dldpre_init, dldpre_exit): unrelate init/exit
from add/remove symlists, so one may add dld_preloaded_symbols
from main(), when only a library will call dldpre_init
(lt_dlopen): use LTDL_SHLIBPATH_VAR, if defined, as secondary
search path. Also, if a requested .la file cannot be found, try
with the LTDL_SHLIB_EXTension instead.
only if --enable-ltdl-install
(CONF_SUBDIRS): list directories that are configured on demand,
but that must be included in the distribution
(ACINCLUDE_M4_LIST, DIST_MAKEFILE_LIST): generated from CONF_SUBDIRS
* Makefile.am (AUTOMAKE_OPTIONS): added version 1.3e and
readme-alpha, to handle README-alpha automatically
(EXTRA_DIST): removed README-alpha
(BUILD_SUBDIRS): subdirectories that are always built
(SUBDIRS): BUILD_SUBDIRS plus BUILD_LTDL
(DIST_SUBDIRS): BUILD_SUBDIRS plus CONF_SUBDIRS, from configure
(all-local, check-local): depend on $(ACINCLUDE_M4_LIST), from
configure, and libtool, so that it is built before subdirs
(configure-subdirs): new target
(configure-subdirs, distdir): depend on $(DIST_MAKEFILE_LIST),
from configure
(@DIST_MAKEFILE_LIST@): create subdir if needed, then run
configure.
On-demand configuration of subdirs at distribution time was
suggested by Gary V. Vaughan <gvaughan@oranda.demon.co.uk>
* 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
depdemo commented out, so that `dist' works before `check'
(BUILD_LTDL): will contain libltdl if --enable-ltdl-install
* Makefile.am (DIST_SUBDIRS): expand SUBDIRS and add depdemo,
commented out
(SUBDIRS): add $(BUILT_LTDL)
* libltdl/Makefile.am (EXTRA_LTLIBRARIES): add libtest.la, the
same as libltdl but always a convenience library. Not built by
default. Both libraries now depend on the libtool script, that
depends on ../libtool and is rebuilt when needed
* mdemo/Makefile.am (mdemo, mdemo.debug): depend on and link with
../libltdl/libtest.la, that is rebuilt if needed
(mdemo_LDADD): removed $(LIBADD_M), to avoid silent failures
(foo1.la): renamed from libfoo1.la; test removing the lib prefix
* mdemo/foo1.c: renamed libfoo1_LTX symbols to foo1_LTX
* mdemo/main.c: don't include string.h nor math.h, nor refer to
sin nor cos
* tests/mdemo-exec.test: renamed libfoo1.la to foo1.la
* tests/mdemo-inst.test: ditto
and don't redefine it if already defined; default to 1024, as on
most systems
(LT_SYMBOL_LENGTH): renamed from MAX_SYMBOL_LENGTH
(LT_SYMBOL_OVERHEAD): new macro, that accounts for the size of
the _LTX_ separator and the initial underscore
(lt_dlsym): sym now points to a stack buffer (lsym) if possible,
or is dynamically allocated. If allocation fails, a
buffer_overflow_error is returned.
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
