Did you read
http://xtalk.msk.su/~ott/en/writings/emacs-devenv/EmacsCedet.html ?

Specifically

,----
| (defun my-c-mode-cedet-hook ()
|  (local-set-key "." 'semantic-complete-self-insert)
|  (local-set-key ">" 'semantic-complete-self-insert))
| (add-hook 'c-mode-common-hook 'my-c-mode-cedet-hook)
`----

I used company-mode as it has far better search and context help for
completion candidates. To use the semantic functions simply comment out
the "(company-mode 1") in the my-cedet-hook in the code below.

My own set up is here:

http://richardriley.net/projects/emacs/dotprogramming#sec-1.1

But borrowed heavily from Alex Ott's excellent article (I struggle
with the CEDET docs as they cover an awful lot of things I haven't a
clue about!).

Company mode:

Please don't do this!  In some CC Modes (C++ Mode, Java Mode, ...), ">"
is bound to `c-electric-lt-gt', which deals with all sorts of nasty
things that happen when ">" is a template bracket, or might be one.
(Don't blame me for the stupidity/malice of the idiots who thought that
the greater-than sign was so pretty it could be abused as a parenthesis,
leading to syntactically unparseable code.)

Please be careful when rebinding "ordinary" keys.  Particularly in CC
Mode, quite a lot of ordinary looking keys are actually "electric" keys.

Hmm.  You have an illicit '(local-set-key "\C-c\C-r" ...' in that file.
C-c C-<letter> belongs to the major mode.  You _probably_ meant to use
C-c r.  :-)

I didn't. Please see the link above!

emacs C++ auto code completion problem

[GMS S]

Hi,
The C++ auto code completion is not working with emacs.
Reading this http://cedet.sourceforge.net/setup.shtml

make EMACS=emacs

And added in .emacs file

(load-file "~/cedet-1.0pre6/common/cedet.el")
(global-ede-mode 1)                      ; Enable the Project management system
(semantic-load-enable-code-helpers)      ; Enable prototype help and smart completion 
(global-srecode-minor-mode 1)            ; Enable template insertion menu

But it is not working.
If I run a .cpp file with emacs and after typing dot(.) no menu is shown.

Would someone please tell where is the mistake?
