Re: [mesa-users] Configuring mesa-11.2.2 llvmpipe with non-standard paths

I almost forgot about this issue!  Your libGL is the result of conflicting
options for competing Xlib GLX implementations.  I actually fixed this in
upstream and configure options for glx are a bit more sane now in the
upcoming 12.0 release.  Basically try some different configure options
followed by a bit of surgery after the installation (note that these are
the configure options we use with Mesa):

./configure \
  --enable-opengl --disable-gles1 --disable-gles2           \
  --disable-va --disable-gbm --disable-xvmc --disable-vdpau \
  --enable-shared-glapi                                     \
  --disable-texture-float                                   \
  --disable-dri --with-dri-drivers=                         \
  --enable-gallium-llvm --disable-llvm-shared-libs          \
  --with-gallium-drivers=swrast                             \
  --disable-egl --disable-gbm --with-egl-platforms=         \
  --disable-gallium-osmesa --enable-glx --enable-xlib-glx   \
  --with-llvm-prefix=${BASELIBS_PREFIX}/llvm-3.8            \
  --prefix=${BASELIBS_PREFIX}/mesa-11.2-glx

make -jwhatever install

What you'll end up with in the install directory is a bit of a mess
though.  If you look in there, you'll see both libGL.so.1.5.0 and
libGL.so.1.6.0 with associated symlinks mixed for both.  Delete the
libGL.so.1 symlink and the libGL.so.1.6.0 library and then re-create the
symlink for libGL.so.1 -> libGL.so.1.5.0.  The resulting install tree after
all this should give you a working libGL.so that correctly sees llvmpipe.
All this is fixed in upstream now, see:

https://bugs.freedesktop.org/show_bug.cgi?id=94086
and
https://cgit.freedesktop.org/mesa/mesa/commit/?id=a92910ae37878b441ecb1c488f0a40d80a48f6fe

12.0 you can just give --enable-glx and the correct backend will be chosen
but for the current release you still have to get your hands a bit dirty.
