Hello, Dmitry!

I... well, I have already read that guide. But I tried again this time,
So I did these changes:

on my hooks.el file have no changes under the after-init-hook, which
starts semantic-mode.

On my conf-modes/cedet.el file I did these changes:


(add-to-list 'semantic-default-submodes 'global-semanticdb-minor-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-highlight-func-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-scheduler-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-completions-mode)
(add-to-list 'semantic-default-submodes 'global-semantic-idle-summary-mode)

(when (cedet-cscope-version-check t)
  (semanticdb-enable-cscope-databases))


Of course I load them from my varl.el file:


(load-file "~/.emacs.d/conf-modes/emacs-behaivor.el")
(load-file "~/.emacs.d/conf-modes/localization.el")
;; ...
(load-file "~/.emacs.d/conf-modes/org-mode.el")
(load-file "~/.emacs.d/conf-modes/autoindent.el")
(load-file "~/.emacs.d/conf-modes/cedet.el") ;; This runs before (semantic-mode 1) is evaluated... Or thats what I think...
(load-file "~/.emacs.d/conf-modes/company.el")
(load-file "~/.emacs.d/conf-modes/auto-mode-alist.el")


That's all the changes I did, I swear! Then I restart my emacs, but this
error shows up:


Debugger entered--Lisp error: (void-function cedet-cscope-version-check)

Looks like cedet-cscope-version-check dont have a function defined, I
wonder why because I have CEDET 2.0 shipped from Emacs and according to
the guide it should be evaluated like a function.
Any idea of what (why?) is happening here?
