Hi

I have a strange problem, having compiled llvm 4.0.0rc2 and then tried to
compile mesa 17.0, it fails with this:

>From that command and error, it looks like Make is trying to compile this with
g++ instead of clang++ and if i manually replace it (and in another places), i
can compile mesa 17.0.

So what is failing here? it is using the LLVM_CXXFLAGS and the gcc g++.
I had the mesa 17.0rc3 compiled just fine with llvm 3.9.1.


i'm using slackware64-current, kernel 4.10.0, gcc 5.4.0, automake 1.15


Thanks
