Trying to compile llvmlite or numba from https://github.com/numba I am getting
g++: error: unrecognized command line option ‘-Wcovered-switch-default’
any help on how to fix this would be most appreciated. - mark

See https://github.com/numba/numba/wiki/Build-0.33-on-ubuntu-16.04 for a solution: basically make sure to the use the llvm that comes with the distribution:
apt-get install llvm-3.9
export LLVM_CONFIG=$(which llvm-config-3.9)
=> will work ok
Why? its beause the llvm that you can downlaod from http://llvm.org was built with clang, whereas the one that comes with the distribuiotn was built with g++ (I think)
