With some debugging I've figured out that setting EGL_DRIVERS_PATH to $MESA_ROOT/lib/egl fixes my problem. I'm back in business! ('til I hit the next roadblock at least). Sorry for the spam.

Up until now, I've been working with a mesa codebase that I grabbed way back in April. I'm now trying to migrate to the latest version of mesa (and "rebase" daily) so that I can send my changes to you folk for review. However, it seems my old ways of building no longer work. Specifically, I used to do: ./autogen.sh --with-state-trackers=egl,es,vega --enable-gallium-swrast make export LD_LIBRARY_PATH=$MESA_ROOT/lib export EGL_DRIVER=$MESA_ROOT/lib/egl_x11_swrast.so When I try that today, egl_x11_swrast.so does not get built, and (not surprisingly) EGL initialization fails. Any hints? Are the build instructions documented somewhere? This trial-and-error approach is getting tiresome ;) Thanks so much for your help! If you can get me through this I'll have some exciting patches for you guys! -Greg Prisament, Lychee Software </blockquote></div>
