Hi Bill, The problem is not in the invocation of gcc. That works fine. The problem is that I lose the preprocessor definitions that were added with add_definitions() when compiling assembly files. These assembly files must be preprocessed by gcc. I have the feeling that CMake purposely drops these. So the question is how I can persuade CMake to keep the -D options on the command line.
Note that I have defined an assembler for BG/P that uses gcc as frontend, using the *ASM*.cmake macros mentioned in my previous mail. Best regards, Marcel Loose.
