I got these lines:

;; turn on semantic
(semantic-mode 1)

;; define a function which adds semantic as backup to auto-complete
(defun my:add-semantic-to-autocomplete()
  (add-to-list 'ac-sources 'ac-sources-semantic))

(add-hook 'c-mode-common-hook 'my:add-semantic-to-autocomplete)

From this video here.But for me it does not work at all.Save me please,i lost all day fighting with it...

  • Have you installed auto-complete? Please try to detail what you do, what you expect and what happens instead. – JeanPierre Feb 18 '16 at 16:18

You mistyped your auto-complete source symbol.

It should be 'ac-source-semantic, not 'ac-source(S)-semantic
