This is a Mac OS X hosted cross-compiler suite: * http://www.libsdl.org/extras/amigaos/cross/amigaos-macosx-x86.tar.gz The path to crt0.o had to be hard-coded during the gcc build process, so make sure that you unpack it in /usr/local, and it will create the path /usr/local/cross-tools This was created by roughly following the steps in the cross-compiling guide: * http://utilitybase.com/article?action=show&id=111 and downloading packages from: * http://ftp.back2roots.org/geekgadgets/amiga/m68k/ You can grab the sources I used at: * http://www.libsdl.org/extras/amigaos/cross/src/ Thanks to ike^ who got me started with GeekGadgets on AmigaOS
