Help compiling mesa/gallium from git!

[Bill Spitzak]

Okay, a bit more luck, in that I can compile weston.

I mostly discovered that there are parts of mesa you just cannot turn 
off, no matter how much you are certain they are not used. Mesa 
internally has calls into various functions in these modules from others 
so they cannot be removed.

My current mesa configuration:

   ./autogen.sh --prefix=$WLD --enable-gles2 --enable-gallium-egl \
       --with-egl-platforms=wayland,x11,drm --enable-gbm \
       --with-gallium-drivers=swrast \
       --with-dri-drivers=swrast --disable-dri3 --disable-glx

The most important thing was the dri-driver, otherwise you get the 
_glapi_Dispatch symbol missing. Also x11, drm, gbm, and gles2 are needed 
or mesa just will not compile.

I now have to run wayland with --use-pixman, when before it either 
detected that it needed to use this, or the gl-renderer worked for some 
reason.

I cannot run any egl demos, even though I have been told this will allow 
them to run with software emulation. weston-simple-egl produces this:
