Hey, on mac os x, shrext_cmds is defined like that: shrext_cmds='`test .$module = .yes && echo .so || echo .dylib`' i want to use it in AC_DEFINE_UNQUOTED like that : AC_DEFINE_UNQUOTED(SHARED_LIB_SUFFIX, "$shrext_cmds", [Suffix for shared objects]) how do i get its value in a cross platform way ? thank you Vincent Torri _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
