Debian's version of OpenGL is called Mesa and it supports normal OpenGL on armel too, it would not be hardware-accelerated yet though because there aren't any free drivers for that in Debian. Same goes for hardware-acceleration of OpenGLES on ARM, no free drivers in Debian yet. Some reverse engineering projects and free drivers exist outside of Debian though: https://wiki.debian.org/Mobile#software-drivers You can install OpenGLES (libgles1-mesa-dev or libgles2-mesa-dev) on your standard Debian amd64 PC system, try to build your code and change it until it doesn't fail. This will be hardware-accelerated and be easier than messing around with cross-compilers. Here are some guides for converting OpenGL code to OpenGLES, any issues you encounter should be fixable by using a search engine though. http://pandorawiki.org/Porting_to_GLES_from_GL http://software.intel.com/en-us/articles/porting-opengl-games-to-android-on-intel-atom-processors-part-1 http://wiki.maemo.org/OpenGL-ES Debian plans to add cross-compilers for our next release: https://wiki.debian.org/ReleaseGoals/CrossToolchains Until they reach Debian, here is a page about how to build cross-compilers: https://wiki.debian.org/MultiarchCrossToolchainBuild -- bye, pabs http://wiki.debian.org/PaulWise -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
