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

Looks like a typo in the GCC docs - try '-x cpp-output' instead.

gcc -E helloworld.c > cppout
gcc -x cpp-output cppout -o hw
./hw
Hello, world!
