How can I compile C code that has already been C pre-processed with GCC?

Question

I\'m performing some source processing between C preprocessing and C compilation. At the moment I:

1. gcc -E file.c > preprocessed_file.c.

Answer 1

Save the file with the .i suffix after pre-processing. Gcc man page:

       file.i
           C source code which should not be preprocessed.

       file.ii
           C++ source code which should not be preprocessed.
