Solidity: Cannot build latest develop on OS X Sierra

[VoR0220]

I have tried:

running the install_deps.sh script.

running cmake .. again.

running make -j 2 again.

And each time I'm getting this strange error:

Any ideas for a quick fix?

@VoR0220 have you tried this?

[VoR0220]

I have not. Thanks for the tip. Probably a problem with xcode when upgrading to Sierra.

Yep...that did the trick. Thanks @federicobond !

Thanks @federicobond the link worked for me. Specifically on macOS Mojave I needed to run:
