I'm running into this as well, with the exact same error print out. It works on installing for about an hour, then fails.

Any ideas?

[FranklinChen]

I never got this to work myself either.

[tmcdonell]

LLVM 4 is extremely old at this point; it is possible that it doesn't build on newer macOS / Xcode.

However, you could try updating the build script to match that used by the newer versions; i.e. cmake -G "Unix Makefiles" ... rather than using cmake directly. Patches welcome.

[ChrisPenner]

Yeah; I switched to llvm-9 and it all worked out; I was looking at old installation instructions 🙃
