"'clang-c/Platform.h' file not found" after brew install --with-toolchain

I ran brew install with tool chain llvm and I still get "'clang-c/Platform.h' file not found". Not sure if I am missing a step.

You need a pkg-config file.

sudo swift ClangSwift/utils/make-pkgconfig.swift

@ddddxxx what to do if I'm getting this:

Running /usr/bin/which /usr/local/opt/llvm/bin/llvm-config...
error: Failed to find llvm-config. Ensure llvm-config is installed and in your PATH

?

Is there a build instruction? Or at least a list of system requirements to have?

Update: brew install llvm helped
