This is not possible, in general. It has nothing much to do with libtool either, because typically it's just the system semantics that allow for only one unversioned soname symlink. Users typically work around this by installing different library versions in different $prefix'es. Developers typically hack around this by using the -release flag to rename the library, which comes with its added costs of course (see the manual!). Of course, if you don't have to be able to have multiple versions installed concurrently, then all you do is use a configure test like AC_CHECK_LIB or sisters with the latest-added symbol that you need, or a self-written link test if the latest needed API isn't distinguishable by function symbol alone. Hope that helps. Cheers, Ralf _______________________________________________ http://lists.gnu.org/mailman/listinfo/libtool
