I am trying to install CEDET for Emacs 24.3. I followed the following instructions: http://cedet.sourceforge.net/setup.shtml
When I start emacs, I see that the package-related error is outdated. What can I do about this?
Your question is a duplicate .
But you should not install CEDET for 24.3, as it is already installed with 24.2. Follow my answer in this question if you are interested in completing C / C ++.
