I would use the following for all of this:

(require 'compile)

;; don't prompt
(setq compilation-read-command nil)

;; close the window on successful compile
(defun my-compilation-finish-function-standard (buf str)
  ;; avoid doing this for buffers created from M-x grep
  (when (string-match "*compilation.*" (buffer-name buf))
    (if (string-match "exited abnormally" str)

        ;;there were errors
        (progn
          (message "compilation errors, press C-x ` to visit"))

      ;;no errors, make the compilation window go away
      (run-at-time 0.5 nil 'delete-windows-on buf)
      (message "NO COMPILATION ERRORS!"))))
(add-to-list 'compilation-finish-functions
             'my-compilation-finish-function-standard)
