I expected that answer :( Anyway, I've managed to compile MFC source but got stuck at linking...
1) The output file is mfc.dll.EXE.so which doesn't seem right. Oviously I have to pass some extra switches to either wineg++ or winebuild but I can't figure out the correct ones. 2) I suspect I need a .spec file too, right? Is it possible to generate it from mfc42.def that goes with MFC source? What about C++ name mangling? Serge
