Olivier, When you create a shared library, this library can contain unsatisfied references to other symbols in other shared libs. However, when you load the shared lib, you must load the shared libs in the right order to avoid the kind of messages you are reporting. It could also be that you forgot to implement some member functions declared in your class header. Check that you really declared/implemented: the default constructor the virtual destructor If you have a ClassDef in the header, you must have ClassImp If you do not find which function is unsatisfied, I suggest you create a small main program where you declare a statement like MyClass m; The loader will tell you which function is missing Rene Brun Olivier Meplan wrote: > > Hi Rooters! > > I have a pb with share library ; I have first create a library lib1.so > which contain class descpription.
