Yeah, thanks a lot! I can compile the official-mame now. But with other port of mame, I get into a problem like this: " Compiling icl: not found mingw32-make: *** [obj/mame32-p4/version.o] Error 127 " do you know what problem is it? How can I solve it? Once again, thank you PS: oh one more problem: When I compile mame source with mame32 or mamefx, zetamame source, I always ancounter with a problem: "Compiling scr/ui/treeview.c... In file include from src/ui/treeview.c:46: src/ui/help.h:16:22: htmlhelp.h: No such file or directory" Seem like I have missed "htmlhelp.h" or some file like this. Any help, please?
