I'm using an open source library which seems to have lots of preprocessing directives to support many languages other than C. So that I can study what the library is doing I'd like to see the C code that I'm compiling after preprocessing, more like what I'd write.
Can gcc (or any other tool commonly available in Linux) read this library but output C code that has the preprocessing converted to whatever and is also readable by a human?
cpp is the preprocessor.
cpp filename.c to output the preprocessed code, or better, redirect it to a file with
cpp filename.c > filename.preprocessed.
