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?
