Hey. I've installed the recent linaro image on my udoo and I'm really happy about it, since it's faster than the 11.10. This morning I've tried to install one of my favourite multi emulator, called Mednafen. It's cool since it uses OpenGl and it's really fast, so I downloaded the source from the website and tried to compile it, but there's a problem. When it start searching for OpenGl, it gives me an error about no OpenGl headers. I really don't know what to do, since the new release of the Udoo fixed the opengl errors. Any help? Ps: here is the page of the emulator: http://mednafen.sourceforge.net/ Pss: if you want i can give you a log about the error.
