# Unix.getpid () ;; Reference to undefined global `Unix' This means that it can't access the "Unix" library, although it doesn't bother to say why. It does not mean that the "Unix" library doesn't exist, or that you misspelled its name. It means you needed to launch the ocaml interpreter with "ocaml unix.cma" instead of "ocaml".
