Using CEDET-1.0 pre7 with Emacs 23.2

Reading time ~1 minute

It's been mentioned in several places that GNU Emacs versions sometime after 23.1.50 do come with an integrated version of CEDET. While I think that's a superb idea it unfortunately managed to break my setup, which relies on a common set of emacs-lisp files that I hold under version control and distribute across the machines I work on. Those machines have different versions of GNU-based Emacsen (pure GNU, Emacs/W32, Carbon Emacs etc) so I can't rely on the default CEDET. Unfortunately when I got a new machine and put a GNU Emacs 23.2 on there, my carefully crafted (OK, I'm exaggerating) .emacs wouldn't play ball because the built-in CEDET conflicted with the pre7 that I had already installed on that machine.

I didn't want to have to make extensive modifications to my .emacs, but a little time spent on Google brought up a post by Marco Bardelli on the CEDET-devel mailing list with a little code snippet that removes the built-in CEDET from the load-path. After putting this into my .emacs, my -pre7 config is working again.

For those in a similar quandary, here is the snippet in all its glory:

(setq load-path
      (remove (concat "/usr/share/emacs/" 
              (substring emacs-version 0 -2) "/lisp/cedet")
          load-path))
