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.
