Looks like default Xcode installation through the store doesn't install this package: /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg Tried compiling the lib independently and installing the package fixes the issue. (To install do simply do open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg in a terminal)

If you build the driver with qcow2 which is the default, you're gonna get this error:

[ERROR] The compilation of ocaml-system failed at "/private/tmp/docker-machine-driver-xhyve-20181011-14594-10x1d8n/.brew_home/.opam/opam-init/hooks/sandbox.sh build ocaml gen_ocaml_config.ml".

The current workaround is to do: brew install docker-machine-driver-xhyve --without-qcow2
