* 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.
