I succeded in compiling STK on rapsberry PI (under 2012-10-28-wheezy-raspbian.zip).
But,  full screen in not possible, and artefact on the screen. Moreover, I have 1 image/2 secondes (as you may know, quake 3 runs perfectly under Raspberry Pi).

I don't know if you got an interest for rapsberry PI, but STK (and other games) would be a fun kart game for my TV!

Regards and thank you!
