[Mesa3d-users] using osmesa together with nvidia GL implementation

[Alex F. <ale...@gm...>]

Hi there,

My program is happily linking to the nvidia OpenGL implementation for
its normal onscreen rendering. I would like within a small part of
this program to use the offscreen rendering capabilities of OSMesa. If
I link to both /usr/lib/libGL.so and /usr/lib/libOSMesa.so then I get
strange results: either my offscreen-rendered images are blank or GL
crashes, depending on which order I do the linking.

My first question is: is this even supposed to work? If so I will
investigate further and post much more detailed info about what's
going wrong.

If not, is there any other way that I can get both 3D acceleration for
onscreen rendering and (un-accelerated) offscreen rendering working in
the same binary?

Thanks in advance,
Alex
