I've been using Gentoo exclusively for the last 10 years or so, but the rpi is my first non-x86 machine, so I have a couple of questions. I'd like to use Gentoo as the base OS and build from there.
1) How does the quake III/fuse zx emulator demoed on the pi work without X11? I assume they are patched to use opengl es instead of full opengl? Is that all that it takes + maybe use pi specific libraries?
2) If so, am I right to assume that something similar can be done for e.g. SDL, thus being able to run any SDL based apps right from the framebuffer without the need for X11 (via directfb maybe)? Do the Gentoo builds here support opengl es?
3) Has anyone tried to compile XBMC (the pi "version" with omx*) on Gentoo?
Thanks a lot!
