* doc/libtool.texi (libltdl interface): removed the line which
promised that lt_dlopen will return NULL if it can't resolve all
symbols
* libltdl/Makefile.am, libltdl/configure.in: fixed build problem:
renamed the convenience library to libltdlc.la and the
installed version to libltdl.la
* ltmain.in (wrapper script): replaced the "T" suffix of the program
file name with a "lt-" prefix
* mdemo/Makefile.am: use libltdlc.la
* tests/Makefile.am, tests/demo-nofast.test: added demo to
test --enable-fast-install=no
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
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.
* autogen: only libltdl needs autoheader
* doc/libtool.texi (link mode): documented -export-symbols-regex
and updated -export-symbols
* doc/libtool.texi (script contents): documented
always_export_symbols, export_symbols_cmd, exclude_expsyms,
include_expsyms, dlopen and dlopen_self
more detailed description of need_lib_prefix
* ltconfig.in: a "'" was missing in the default value
of export_symbols_cmd
* ltmain.in: implemented -export-symbols-regex
* *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
* 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/configure.in: use 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
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
link libraries with dependencies on .la libs.
* NEWS: Removed reference to win32, incase 1.3 ships before
ild is ready.
* doc/PLATFORMS: Removed i686-pc-cygwin32, for the same reason.
* doc/libtool.texi: Removed win32 refs, for the same reason.
extension
* libltdl/ltdl.c (lt_dlopen): if a .la file name is given, that's
all. Otherwise, lt_dlopen now tries to append .la first. If this
fails, it tries the given filename, and, at last, tries to append
the native library extension to the given filename.
* doc/libtool.texi (lt_dlopen): explain new lookup strategy
* tests/mdemo-shared.test, tests/mdemo-static.test: ditto
* tests/Makefile.am: ditto
* doc/libtool.texi: document them
* demo/Makefile.am, mdemo/Makefile.am (@STATIC@): do not use
-static unconditionally, it can't work with --disable-static
* demo/configure.in, mdemo/configure.in: check whether libtool was
configured to build static libraries and, if not, set STATIC to an
empty string
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
* 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
(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

modules

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

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>

archive_cmds for cygwin32.
1998-11-04 Ian Lance Taylor <ian@cygnus.com>
