Can't build on MacOS 10.12 Sierra

Installed HHVM via Homebrew. Then run ./build.sh and get errors:

What I am doing wrong? Thank you.

My guess is a lot of the args passed to the HHVM cmake (brew does this for you) will need to be passed to the cmake call in ./build.sh. https://docs.hhvm.com/hhvm/installation/building-from-source#mac-os-x-homebrew__build-hhvm

As far as I know, no one has built this example on OS X.

Thank you for the answer! It not helps... Built HHVM from source, all is the same. So there is any possible to build any extension on osx??
