[Mesa-users] EGL DRI Driver Loading Error

Wed Feb 23 21:47:48 PST 2011

Hi Chai,
 this is the response.
[srini at RHEL2 check_GLES]$ export EGL_DRIVER=/usr/local/lib/egl/egl_dri2.so
[srini at RHEL2 check_GLES]$ ./sphere 
libEGL fatal: DRI2: did not find extension DRI_IMAGE version 1

what does it mean? am i messing up anywhere?

Regards,
Srini
