I use Emacs 23.3 with no changes in internal structure.
I downloaded cedet from by this bzr checkout bzr://cedet.bzr.sourceforge.net/bzrroot/cedet/code/trunk cedet.
I use this: emacs -Q -l cedet-build.el -f cedet-build to build cedet.
Build was completed successfully.
In my .emacs I wrote this:
(load-file "~/.emacs.d/packages/cedet-1.0.1/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) 
But I have an error: Symbol's function definition is void: semantic-load-enable-code-helpers.
Sincerely yours, Kron.
