when I run ./compile -t btrfs -c in lkl, i get some error msg:

I ran into same error msg a while ago. The source of the problem that i found was that i was installing llvm and clang by running sudo apt-get install clang && llvm. Basically these commands was shipping me old version of llvm i.e llvm 3.0 . To resolve the problem I build clang 6.0.0 with llvm 6.0.0 from source.
