We will also be using the system C++ toolchain that comes with the Xcode Command Line Tools. You should be able to use other/custom C++ toolchains, however, this is the only configuration that is tested and guaranteed to work. To verify that Command Line Tools are installed, run: \ $ clang++ --version \ It should produce something along these lines: \ Apple LLVM version X.Y.Z (clang-A.B.C) (based on LLVM M.N.P) \ To install Command Line Tools, run: \ $ xcode-select --install \ Once this is done continue with \l{#bootstrap-unix Bootstrapping on UNIX}.
