Where is the system llvm-config on macOS?

Question

If I'm not mistaken, the compiler etc. installed as part of XCode use llvm. But I can't find an llvm-config binary to generate proper flags for command-line compilation to an llvm target. Where is such a thing on macOS?

I know I can install a new llvm via MacPorts or Homebrew, but I don't want to duplicate what's already there; I just want a way to get at the system configuration.

Answer 1

llvm-config is used to build programs that would link against LLVM. Xcode does not distribute the LLVM libraries, and does not support linking against clang itself, so llvm-config is of no use in this context. What is your use case?
