Open GL

Hi. I’ve been pretty active on the forum and very much appreciate the help so far. This seems to be the last obstacle before I can compile all the software examples (which has become a bit of an obsession.)

deviceQuery, bandWidthTest, and a host of other examples compile and run perfectly now. However when I try to run ./particles I get the following error message

grid: 64 x 64 x 64 = 262144 cells
particles: 32768
Xlib: extension “Generic Event Extension” missing on display “localhost:10.0”.
freeglut (./particles): Unable to create direct context rendering for window ‘CUDA Particles’
This may hurt performance.
Required OpenGL extensions missing.Segmentation fault

I have installed the freeglut package with yum. Do I need an additional driver for OpenGL. If so, where could I download it?

Thanks very much

You need to install libxmu and libxi. I’ve got the same error when I tried to do a remote rendering using ssh -X.
