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

Ok, thanks... but building mesa-git i get this, that is similar to what i get just by removing the bad llvm flag:

i would say that something here do not like llvm 4.0 ... or i may have something broken in my system

This is mixing llvm standard headers while compiling with gcc.
I'd say "-isystem /usr/lib64/clang/4.0.0/include/" is the culprit here.
Not sure where it came from, maybe it needs to be stripped as well.
Comment 4 higuita 2017-03-03 00:00:48 UTC 
humm... "-isystem /usr/lib64/clang/4.0.0/include/" you say... let me check...

yep, this is my fault! i had some problems with llvm 4.0.0rc1 and add that to try to workaround it... and forgot to remove it in rc2. Now the llvmconfig --cxxflags also have this flag.

As this was a "bad option", i think there is no need to remove more flags

So sorry, my bad, i will close this.

But thanks for the help and for mesa!
