git clone https://github.com/llvm-mirror/libcxx.git

cd
mkdir llvm-build
cd llvm-build
cmake -G "Unix Makefiles" ../llvm
make
sudo make install

Thanks a lot for these instructions! We should definitely add them to our ubuntu-dev.dockerfile if they're useful for other developers as well.

Also, thanks for suggesting to build with -DCMAKE_BUILD_TYPE=Release in order to avoid Clang's Debug mode.

You should probably clone the release_40 branches for all the git clone as this is the version the static analysis is based on.

Second suggestion: we should probably use make -j<a lot> instead of make.

Third suggestion: the libcxx step is only for Mac and I think it should't be used for these containers, sorry about that.
