examples/gl/gpuParticleSystemExample failed creating GL_GEOMETRY_SHADER_EXT shader #6648

OpenGL generated error 1280 trying to get the program link status, does your video card support shader programs?

How do I check?

Hello! It could be because that Intel's driver doesn't support GL_RGB32F format. I've had this problem with Intel machines before. More info: https://www.gamedev.net/forums/topic/602099-problems-with-floating-point-texture-formats-and-intel-graphics-under-linux/
