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

[Chuck Atkins]

What's the output of your configure look like?  Using almost the same
configuration on CentOS 6.7 with GCC 5.2 from the SCL, except all system
dev-packages instead my own versions (sans llvm of course) I get the
following output:

[chuck at wopr mesa-11.2.2]$ ./configure
--with-llvm-prefix=${HOME}/Code/LLVM/llvm-3.8.0.inst --with-gnu-ld
--enable-gallium-llvm=yes --enable-sysfs --enable-xlib-glx --enable-glx
--enable-texture-float --disable-dri --disable-dri3 --disable-egl
--disable-llvm-shared-libs --with-gallium-drivers=swrast
...

        PYTHON2:         python2

        Run 'make' to build Mesa

[chuck at wopr mesa-11.2.2]$

Your resulting configure output should be similar.
