If you do a "make clean" followed by a "make all" (or simply "make clean all"), it should rebuild your application from scratch (assuming that the "all" target is defined to do so) and no dependency rules are needed. It will take longer to rebuild since it has to recompile everything, but it doesn't sound like you run this build every day. Alfred
