I checked and the opengl context is created before glew is initialized, at least in the 8-5-08 release. Could you post more information about your crash? What console messages are printed, when does the crash occur, what gfx card/OS are you using, which release are you using, and have you tried running gdb?

a window is shortly appearing (only a black background and no foreground).
I am using (at the moment) the games-sports/vdrift-20080805 ebuild from gentoo.
I can prepare a checkout to the latest version, but because I do not found any bug reports about this problem in the net, I believe it is a uncommon thing (so I thought it was the same problem described above).
What for informations are helpfull for you?

Hey, thanks for all of the info. I suspect this is an issue with use of shaders. For some reason, a few types of graphics cards seem to compile the shaders fine but then crash when they're enabled. I think it's an issue with how I'm detecting success/failure. Anyway, try editing your ~/.vdrift/VDrift.config file and changing "shaders = true" to "shaders = false".
To edit the configuration file solved the problem.
Perhaps you are able to use another detection...
I can proof the code than on my system for tests.
Thanks
Same problem and same solution here, running windows XP SP2 and the .exe version 2008-08-05-full.
But I tried to compile it under ubuntu using the svn version with no success.. will try again later at home.
cya.
What kind of graphics card do you have?
