Try the latest pre-release: http://www.virtualgl.org/DeveloperInfo/PreReleases I think one of the patches OpenText contributed in the past couple of days should fix this. Not sure why Mesa advertises support for that extension but doesn't actually provide the function symbol, but VirtualGL now checks for the presence of glXCreateContextAttribsARB() in the underlying OpenGL library before it reports to the application that GLX_ARB_create_context and GLX_ARB_create_context_profile are available. ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
