Running Mac OS 10.6.8 Compiler

[zekecode]

hello, need help.  I downloaded the CodeBlocks but I'm running A Mac 10.6.8.  Compiler says the following:

"Can't find GNU compiler executable in your configured search path's for GNU GCC Compiler."

I want to compile C89.  What should I set CodeBlock to in Settings > Compiler?

Thanks in advance!

Do you have a compiler installed?
CB doesn't include one.
