[VirtualGL-Devel] Bug in virtualGL 2.3.1 with core OpenGL profile + fix

[Antony R. <ka...@gm...>]

Hi,

When creating a core OpenGL 3.x+ profile using bumblebee, the new context
fails when passing
through server/pdrawable.cpp line 264. The check fails on a core profile
3.x+ context because the extension does not exist for such profiles (It is
considered core functionality, not an extension). At least NVIDIA drivers
do not advertise this as an extension. You should consider this extension
as supported on OpenGL contexts with version > 3.0. In fact, for such
contexts using glGetString(GL_EXTENSIONS) to check for extensions is
considered an error. You should use glGetStringi instead.

Thanks,

Antony Riakiotakis
