run c precompiler alone

[rembremading]

Hi all!

maybe somebody here knows whether there exists a way to view the source code
after it ran through the precompiler.
Or, if this is unreadable if there
I have a code with many precompiler commands in it and I would like to see
the code after such statements like
#ifdef SOMETHING
....
#endif
if SOMETHING has not been defined, have been removed.
I am using gcc.

Thanks,

Andreas

It depends on the compiler you're using. Try cpp.

Depends on your compiler (i.e., gcc), so off-topic here. However, I
think gcc -E does the job.

Thanks, that's what I searched for. Sorry for being off-topic.
