Hi, Sorry for possible spams. I am having trouble on getting CEDET code autocompletion to work under Emacs. Having looked at this tutorial http://alexott.net/en/writings/emacs-devenv/EmacsCedet.html#fn.2 However, it doesn't talk specifically about how to get Lisp code autocompletion work. After I did the basic setup, and used "M-X semantic-ia-complete-symbol", I got the error "Cannot analyze buffers not suported by Semantic". My buffer is a .cl file. Can someone help me on this? Best, Yuan
