DarkRadiant Linux Issues
From Dark Wiki
64 Bit Linux Support
Support for AMD64 or other 64 Bit Linux systems should work overall. The scons compilation script has already been prepared (-fPIC switch is required), but there might be some legacy, non-portable C libraries still causing problems (the DDSLib was such a candidate, for instance). If you experience reproducible crashes on your system, please contact the developers, maybe it can be easily fixed.
Crash when using ModelSelector / loading maps with models
DarkRadiant is using glVertexAttrib*ARB function calls to render the models, which requires the GL_ARB_vertex_shader OpenGL extension. This is not provided by the standard Mesa driver installed by Ubuntu Feisty, for instance. You'll need to install the proprietary ATI/nVidia drivers to get DarkRadiant to work here. To find out what driver software and version you're using, type
glxinfo | grep version
into the console and check the line labeled OpenGL version string.
Alternatively, you can open Help -> About in DarkRadiant, which shows the active OpenGL renderer.
