I've gotten it to be able to use a gcc-cross compiler to compile the openxdk samples in linux.
You need to get and install.. hrm where is it..
http://members.lycos...sh.i586.tar.bz2install that, install openxdk into /usr/local/openxdk I believe is where it wants it.. then add some softlinks from /usr/local/openxdk/bin to the /opt/cross-tools or wherever you installed the cross compiler.
you're gonna need a new version of cxbe, actually.. so far this is a problem for me I haven't figured out how to run this in linux, it crashes the version of wine I'm running and I haven't been able to compile it yet.
oh and don't use an executor bios, they won't work. This is a documented bug with openxdk and isn't solved yet.
and there you go. I'm gonna write this up into a nice tutorial soon, once I've ironed out all the bugs.
