Hello again,

        following this example:

        TObject.hpp:

                class Tobject {
                        ...
                };

                extern "C" {
                        void * init();
                }

        TObject.cpp

                void * init() {
                        return (new Tobject());
                }

        I create a DLL, g++ -c Tobject.cpp
                g++ -shared -o Tobject.dll Tobject.o

        When calling the init function after initialising everything
with
        dlopen, dlsym, dlcose... It's generating a segmentation fault,
is
        it due to the load and unload of the DLL? Even if I don't call
the
        dlclose at the end, it's still doing the segmentation fault, is
there
        a way of passing the pointer from the DLL to the main program
using
        dlopen/dlsym stuff?

        Let me know if I can't ask this kind of question to the list ;-P

Thanks in advance,
Lucien.
