There's a gcc command line example in this doc:

http://www.ruby-doc.org/docs/ProgrammingRuby/html/ext_ruby.html

Make sure you have the ruby development libraries (e.g. in Ubuntu you 
need ruby-dev and build-essential). That's another thing - this all 
varies very much depending on which platform you're trying to use, and 
you haven't even given this most basic piece of information.

If you are new to C as well, this is probably not the best place to 
start.

You could try the RubyInline gem for embedding small snippets of C 
directly in your Ruby, which might be useful depending on what it is 
you're actually trying to achieve.
