Hello , i am trying to compile mesa from git source . i got the source from
git clone git://anongit.freedesktop.org/git/mesa/mesa

next i did 'apt-get build-dep mesa' . When i run ./configure i get following error
configure: error: LLVM 3.9.0 or newer is required for r600

but when i do clang --version it shows following output
clang version 3.9.1-4ubuntu3~16.04.2 (tags/RELEASE_391/rc2) Target: x86_64-pc-linux-gnu Thread model: posix InstalledDir: /usr/bin
and output of alternatives is this
`sudo update-alternatives --config clang
There are 2 choices for the alternative clang (providing /usr/bin/clang).

Selection Path Priority Status

0 /usr/lib/llvm-3.9/bin/clang 100 auto mode
1 /usr/bin/clang-3.9 100 manual mode

  • 2 /usr/lib/llvm-3.9/bin/clang 100 manual mode
    `

I am not sure how can i make configure script to detect LLVM 3.9

clang is not LLVM development libs. You would need those to build radeon.

This issue tracker is only for vc4 and v3d development, though. You should look at upstream Mesa.
