I was having trouble getting devkitcube or devkitPPC to work, so I went looking around at the gc-linux project to see what compiler they were using, and turned up links on how to build the GNU toolchain for the powerpc-gamecube-linux-gnu target. You can use it to build flat .DOL images or you can make apps to run on gc-linux (which is still in its fledgling state, btw). http://voidpointer.org/gc-linux/cross_compiler.html (I had some problems with this, but it's informative nonetheless and should work despite the problems I had) http://www.gc-linux.org/docs/howtodevelop.html (brief information on how to develop for the gamecube and upload DOLs) http://prdownloads.sourceforge.net/gc-linux/uclibc-toolchain-src-20040609.tar.bz2?download (A ready-to-build copy of the GNU toolchain for powerpc-gamecube-linux-gnu target. Must be built with an existing copy of the GNU toolchain, either on linux (native gcc) or windows (minGW would work fine).) Hope this helped someone else.
