Support for macOS

I see that there's a file for Darwin support, but when I try getting this package on macOS, I get these compilation errors.

Is it possible that this package is trying to use Apple's LLVM (installed through Xcode) instead of the Homebrew version?

Apple LLVM should be fine, I believe that's what we're using to build the macOS binaries. However, it may be a problem with macOS Catalina.

Can you share the output of the following?

/usr/local/opt/llvm@9/bin/llvm-config --cppflags
/usr/local/opt/llvm@9/bin/llvm-config --ldflags --libs --system-libs all-targets analysis asmparser asmprinter bitreader bitwriter codegen core coroutines debuginfodwarf executionengine instrumentation interpreter ipo irreader linker mc mcjit objcarcopts option profiledata scalaropts support target

And also, can you try export CC=clang-9 CXX=clang++-9, to explicitly use the Homebrew version of LLVM?

Yeah, I guess this is due to changes in Catalina.

Here's the output of the LLVM config program:

$ /usr/local/opt/llvm@9/bin/llvm-config --cppflags

I think this can be closed now.
