[Mesa-dev] Help required in configuring mesa 3d in non X environment.

[Sanjoy Saha - ERS, HCL Tech]

Michel,
    As per the below instructions i tried to compile mesa as follows. But i get a compilation error in make process. Can you please help me out here ?

I'm not sure offhand about compiling without any X headers / libraries
installed, but it's definitely possible to run hardware accelerated
OpenGL (or ES1/2) without X via EGL. The following options for the Mesa
7.11 configure script should help achieve this: --enable-gallium-egl
--with-egl-platforms=drm --enable-shared-glapi
--with-gallium-drivers=r600 (--enable-gles1/2)

Try running any *_screen EGL demo, e.g.

EGL_LOG_LEVEL=debug eglgears_screen

If there's a problem, the EGL_LOG_LEVEL=debug environment variable
should give some useful debugging output.
