Hi Djekic, a.h is malformed. It violates ODR. >a.h is not the file I could change. You either have to change it, or you have to rewrite it. As it stands, a.h is malformed. Look on s9.2.1 of Stroustrup's C++ Programming Language (3rd or Special edition). Those are the kinds of things that go in header files. a.h contains things that should not be present in a header file. HTH, --Eljay
