First I have to thank, because There is rendered something.
After a few changes the engine compiles fine and even the demo scene is working fine(using the OGLES 1 driver) if i compile with X11 Support.
I can't say if it works because i applyed a patch to libEGL.so:http://www.youtube.com/watch?v=8Fy63w6WxOw
or because of the modifications made by hybrid, but until now I didn't get any Picture.
Later I will disable X11 Support in IrrCompileConfig.h and see if it works again.
But for that I will use an new Image of Raspbian, because i don't have a backup of my libEGL.so and also because there where alot of changes regarding audio support some time ago.
