This means that hh_client executable was called and returned something other than "No errors!".

Yep, exactly. You need to run `hh_client` and fix any errors that the typechecker points out. You should be running `hh_client` often anyways, since that is what enforces most of Hack's type system. http://docs.hhvm.com/manual/en/install.hack.bootstrapping.php has details on this process. – Josh Watzman Feb 04 '15 at 02:55
