CodeBlocks Problem

So I want to start developing on my Dreamcast. Well I got everything from the Dev ISO Rev 4 set up, but when I create my Dreamcast project, and it gets to the Compiler options, there are no compilers in the drop down box, even though I have a default compiler set. I tried creating a console project, and I can create and run it fine. It seems to only be the DreamCast project that does this. Can someone please help!

Ok, I can now create the Dreamcast project but when I build it I get over 50 errors all in the included files.
