Hi Chia,

Thanks for your response, it worked well.

I have another question but first I think I need to give some context.

I'm trying to build an environment on my laptop which mimics what I'm
going to use on an embedded target. What I expect to find on my embedded
target is a closed source libGL (EGL + GLES2.0) which is bound to the
linux frame buffer interface as native system. Hopefully I will have
access to an SDK which permits to "repackage" the GL library so it will
use x11 as native system.
Also I'm planning to use an X11 compositor to render the different
applications which run on the system, and also I expect applications to
use OpenGL for whatever stuff they need.

In this scenario, I understand that everyone (including the xserver)
will use direct rendering (which means to me that no one is going to
forward its GL commands to the xserver, but maybe did I misunderstood
something).

So my question is, how do I build such a system ? To be precise, what
options should I give to the configure script of Mesa ?

Maybe am I wrong about this. Maybe indirect rendering will out perform
direct rendering in such configuration, so anyone comments/advices on
the subject are more than welcome.

Thanks again,
