Libtool looks for and uses information provided by installed libtool library files (*.la). In order to be able to find them, it has to know the default search path of the link editor (see sys_lib_search_path_spec). Libtool also hardcodes paths to libraries that end up in places not found by default by the runtime linker; therefore, it also has to know the default search path of the runtime linker (sys_lib_dlsearch_path_spec). Hope that helps. Cheers, Ralf _______________________________________________ Bug-libtool mailing list Bug-libtool@gnu.org http://lists.gnu.org/mailman/listinfo/bug-libtool
