How to compile C source code without a main function?

Question

How can I compile my C source files without needing to put a main function within them?

I get an error for the .cfiles that have no main function and don't want to have to add the main function just for compilation.

On GCC, the -c switch is what you want.

-c means "compile, don't link", and you get a name.o output file.
