The new mesa you built has no egl_gallium.so (since you have
--disable-gallium-egl), but you have not removed the old egl_gallium.so,
and it tries to load it, since it is here.

In order to try to compile the new xserver for wayland, I updated mesa
to the latest git version, and now wayland does not work at all!
Considering it has worked for a long time I would like to try to fix
this, it is really unfortunate.
It does appear the problem is in egl gallium and it's software
fallback. Pekka you were just talking about this in another thread so
I thought you may have an idea what is wrong, or perhaps what I should
do to get around it.
Running weston in the debugger with the debug symbols turned on
produces this (this is from inside a terminal on X so I am using the
X11 compositor):

This does appear to be in egl_gallium.so, which is recently compiled,
I am not sure why I get the "Source file is more recent" error.
Mesa is built with the following config line, which is ridiculous
complex and probably the source of my troubles, but I really have no
idea what any of this means:
./autogen.sh --prefix=$WLD --enable-gles2 --disable-gallium-egl \
--with-egl-platforms=wayland,x11,drm --enable-gbm \
--enable-shared-glapi
--with-gallium-drivers=r300,r600,swrast,nouveau \
--with-dri-drivers= --disable-dri3
Thanks for any help!
