glXCreateGLXPbufferSGIX missing from parallels-tools libGL.so

I'm running debian squeeze with kernel 2.6.32-5. I have a piece of openscenegraph code that is trying to link with libGL. It works for the non parallels-tools version of libGL. It gives me the error after parallels-tools replaces the libGL.so with libGL.so.7.0.15054.722853.

According to nm --dynamic libGL.so.7.0.15054.722853, the symbols aren't there. Have they been moved somewhere else? Do I need to do something special when building the tools?

Any help is appreciated.

Hi,

have the same problem with OSG here - missing symbols on Ubuntu 12.04:

../../lib/libosgViewerd.so.3.0.1: undefined reference to `glXCreateGLXPbufferSGIX'
../../lib/libosgViewerd.so.3.0.1: undefined reference to `glXQueryGLXPbufferSGIX'
../../lib/libosgViewerd.so.3.0.1: undefined reference to `glXDestroyGLXPbufferSGIX'

did you overcome it somehow?
Cheers...
 
runs with SGIX extension disabled...

Hi,

until the extensions are supported by the parallels gl library, I think the best workaround is:

1) open src/osgViewer/PixelBufferX11.cpp
2) insert "#undef GLX_SGIX_pbuffer" around line 280 (for OSG 3.0.1)
3) close file and compile

Cheers...
 
This has been a long-running problem with OpenSceneGraph builds running on Parallels-hosted virtual machines. The root of the issue is that the OSG packages are binding to the older GLX_SGIX_pbuffer extension (GLX pre- version 1.3) rather than the newer Pbuffer capabilities which are core in GLX version 1.3 and later (see http://www.opengl.org/sdk/docs/man2/xhtml/glXCreatePbuffer.xml).

Parallels GL drivers do not include the older version.

So until the maintainer of the OpenSceneGraph .debs fixes the build, we are stuck with doing builds of OpenSceneGraph ourselves, with the modifications mentioned above by ClemensA.
