1998-11-04 Alexandre Oliva <oliva@dcc.unicamp.br> * 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.

* merged my inter-library dependencies code from the ILD branch: * NEWS: inter-library dependencies are now supported * configure.in: add the depdemo subdirectory * depdemo/*: new demo to demonstrate inter-library dependencies * tests/depdemo*: new tests for depdemo * ltconfig.in: added hardcode_into_libs (whether library paths should be hardcoded into the libraries), it currently defaults to 'no' * ltmain.in: new internal 'relink' mode to relink libraries on platforms with hardcode_into_libs=yes, save command line arguments in libtool_args, accept relative -L directories, ignore -lm on BeOS and Cygwin, always ignore -lc, handle -l, -L and .la arguments later, always make the library installation directory (-rpath) absolute, in relink mode don't delete the not-relinked library and exit immediately after relinking, try to find already-installed libtool libraries that were specified using -l, support hardcoding of library paths into libraries too, export shlibpath before linking libraries, and a lot of other big changes that I don't want to describe here... please read the source. * merged Gary's Win32 code from the ILD branch: * NEWS: Win32 DLLs are now supported * TODO: removed .a library namespace clash for win32. It is now resolved. * ltconfig.in (cygwin, library_names_spec): removed $libname.a. Creating a dll with libtool no longer creates an import library. * ltconfig.in (extract_expsyms_cmds): Create $objdir if it does not exist -- i.e. we need to generate import an import library in a directory which has no libs of its own. * doc/libtool.texi (old_archive_from_expsyms_cmds, extract_expsyms_cmds): documented these new variables. * ltconfig.in (extract_expsyms_cmds): New variable. Commands to extract the exported symbol list from a dll. (old_archive_from_expsyms_cmds): New variable. Commands to build an old archive from the extracted expsyms list. * ltmain.in: run the cmds in extract_expsyms_cmds and old_archive_from_expsyms_cmds as necessary. * ltconfig.in (cygwin, old_archive_from_new_cmds): no longer required. * ltconfig.in (cygwin, shlibpath_overrides_runpath): I'm not even sure whether win32 honours the runpath at all when searching for a dll to load! Anyway, when set to yes this prevents a gratuitous warning. * ltmain.in (deplib): The cygwin environment doesn't actually have -lm, and although the linker fakes having one, specifiying it to libtool will break ILD, so we ignore it when generating dependencies.
