GL_ARB_cl_event

hi all..

I want to use the glCreateSyncFromCLEventARB() call on Ubuntu Lucid 64-bit, and i have the latest mesa-common-dev headers and ati stream sdk 2.2 but can't find a definition. Does anyone know how i can access it? I have an HD 5800 series board.

thanks!

I have an OpenGL and an OpenCL thread sharing a buffer and i assume i need this function to allow OpenGL to tell when OpenCL has finished with the buffer.

Digging around a bit, the Catalyst 10.8 driver doesn't seem to contain this ARB as far as i can tell. Maybe there is a rough timetable for support somewhere?

you must download and copy header file from khronos. http://www.opengl.org/registry/api/glext.h

this extension was introduced with OpenGL 4.1. current driver support only 4.0. so driver will support this extenion in the future.
