How to dump all predefined symbols known to the compiler?
« on: August 12, 2014, 09:09:32 pm »
Hello guys, I am relatively new to programming (I am a student) and I am wondering how I can dump all the predefined symbols used by the codeblocks (gcc) compiler?

Thank you very much.

Are you talking about the defines? Then you can compile a simple source file and tell the compiler to dump the preprocessed source instead of generating object file.

For gcc I think it is something like: gcc -E main.c or g++ -E main.cpp, but I could be wrong of course, so consult the manual.
