[Mesa-users] Trouble compiling MesaGL : llvm intrinsics seem to be missing.

Thu Nov 3 03:34:26 UTC 2016

I would remove this line from configure.ac and rerun ./autogen.sh:
AC_MSG_ERROR([gallium_osmesa requires the gallium swrast driver])
then try the top config again with these changes: Omit --enable-osmesa
since  that is the classic osmesa which is a slower alternative to
--enable-gallium-osmesa.

swr is for distributed computers, it is faster than swrast, but for
non distributed computing environments you will want to use llvmpipe
which is faster than softpipe (which in turn is faster than swrast)
but requires llvm and x86.
I don't know what "configure: error: Unknown Gallium driver: llvmpipe"
is on about.
That last configuration of yours builds no drivers so will result in
an unworkable mesa.
