Hi Tom,
Thanks for your reply. We are working with mesa-8.0.4 on Ubuntu 12.04 and compiling the mesa with following options(hardware rendering enabled) and found that there is no Winsys is enabled for "radeon/drm" and it has only "SW" winsys. After this we took mesa-9.0.1 and configured and found radeon/drm is enabled, but compilation is not successful with the error attached. Our intention is compile mesa with opengles2 only with gallium driver(R600) and run es2 demo program which are in mesa-demos.
Mesa-8.0.4 :

Can you please let us know whether we can build the mesa for only opengles2 without opengl ? (--disable-opengles2 and -disable-opengl), and if it is how to build mesa for opengles2 only. And I have looked at : http://mesa3d.org/opengles.html and in this they mentioned -enable-opengles2 and -enable-opengles2 for Gallium driver hardware. To work with gallium driver is it required both opengles1 and opengles2?
Thanks in advance.
Thanks and Regards,
Ramesh

A little more information such as what source you're attempting to
build, config options.
Have you looked at : http://mesa3d.org/opengles.html
etc etc.
