If you use Libtool/libltdl for portable modules (which you do not seem to do), look at Libtool branch-2-0 or CVS HEAD, which allows ltdlopen'ing from libraries. Make sure to read the corresponding documentation pertaining to libltdl, make use of `-module' and `-export-dynamic'. > PS: All this happens using linux system. If you want to be GCC/GNU ld specific only, you can use --export-dynamic for exporting symbols to dlopen'ed modules. If this is not enough help, don't hesitate to ask for details. If you could provide a small example that reproduces the failure, the better. Cheers, Ralf _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
