I've just uploaded a new version of Gpipe that fixes these bugs: * Textures should now work on OpenGl 2.1 (required OpenGl 3.x previously). Thanks to Jake for the bug report. * Added link to GPipe homepage. Still not much there though (just Jake's example code), check back in a few days. /Tobias Bexelius

Speaking of texture, I tried rendering to a texture and sampling it and got an error:

Main: user error (unknown OpenGL extension entry glUniform1uiv, check for OpenGL 3.1)

I'm on Linux 2.6.30 with Mesa 7.5.1. Of course Mesa doesn't have support for OpenGL 3.1 yet, but your description of GPipe says it only needs OpenGL 2.1. Is this a GPipe bug or something else?
