As it happens often with templates you define Execution::TEventHandle only in a header of lib A and the specialization Execution::TEventHandle<Execution::EventBody> then gets instantiated in lib B and the executable. Check your libs and executable with "nm -C" for (I think) typeinfo for Execution::TEventHandle<Execution::EventBody> If this symbol is only defined in one DSO and undefined in the others it should work. Else they use their own local symbol and thus seemingly a different type. You can fix this issue by doing an explicit specialization in lib A and moving at least one function of TEventHandle out of the header into a .cpp file of lib A. (AFAIR -- it's been a long time since I messed with errors of this kind.) Regards, Matthias
