(Said feature isn't > available in earlier releases): Thanks Jeremy... My usage for versioned symbols would be to have multiple shared libraries implementing the same entrypoints... For dlopen'ed libraries, I suppose there is no problem with unversioned symbols, correct? But I want a kind of Windows DLL semantics... If my app dynamic loads lib1 and lib2, that implements the same functions and latter it loads lib3, a different library linked against lib2 (-l2). I want that calls from lib3 always go to lib2. Are versioned symbols the only way to achieve that or there is another way? Thanks, Adriano
