Is it possible to use OpenGL by compiling MesaLib with --enable-gles1 and --enable-gles 2 flags? I've compiled MesaLib on device with these flags using Tanners gcc4.4

Output from ./configure --enable-gles1 --enable-gles2

Code:

        OpenGL:          yes (ES1: yes ES2: yes)

Output from ./glxgears

Code:

Nokia-N900-40-4_PR_001:~/build/glx$ ./glxgears 
86 frames in 5.0 seconds = 17.117 FPS
158 frames in 5.0 seconds = 31.400 FPS
155 frames in 5.0 seconds = 30.947 FPS
159 frames in 5.0 seconds = 31.672 FPS
Nokia-N900-40-4_PR_001:~/build/glx$

*to actually see the gears, the window needs to be fullscreen
rootsh wmctrl -i -r $(wmctrl -l | grep 'glxgears' | awk '{print $1}') -b add,fullscreen

Output from glxinfo | grep rende

Code:

direct rendering: Yes
OpenGL renderer string: Mesa X11

Full output from glxinfo -v
