Carlos, please use Help->Send Bug Report... or M-x report-emacs-bug as suggested in http://www.xemacs.org/Debug/index.html This will tell us enough about your XEmacs installation so that we should be able to help you. If XEmacs does not build or start up, please send any version and configuration information you have to xemacs-beta(a)xemacs.org with any mailer as plain text (MIME attachments are OK, please don't send HTML mail). On linux type ulimit -c unlimited in the shell before starting XEmacs from it, else you might not get a core file. Best regards, Adrian Carlos> Installed XEmacs-21.4.9 on Windows 2000. Carlos> When I try opening a .c file, I get the following messages. "Mode c-mode Carlos> is not installed. Download package (prog-modes 1.60)" & then "File mode Carlos> specification error: (error "c-mode")". Carlos> I installed the sumo-tarball packages. I also installed the cc-mode Carlos> package separately. Carlos> I tried putting Carlos> (load-file Carlos> "C:/progra~1/XEmacs/XEmacs-21.4.9/xemacs-packages/lisp/cc-mode/cc-mode") Carlos> in my init.el. Also tried Carlos> (require 'cc-mode) Carlos> and Carlos> (load-library "cc-mode") Carlos> and Carlos> (setq load-path (cons Carlos> "C:/progra~1/XEmacs/XEmacs-21.4.9/xemacs-packages" load-path)) Carlos> I still get the same messages. So it seems it's not finding my cc-mode Carlos> package and for some reason it's looking for c-mode which I don't have. My Carlos> packages are right under the XEmacs-21.4.9 directory. cc-mode is in the Carlos> xemacs-packages/lisp/cc-mode directory. I had similar problems on 21.4.6 & Carlos> 4.5. I never ran into any problems when I was on 21.1.xx. But since my Carlos> hard drive crashed I've been trying to load the latest of everything. Carlos> Any help would be greatly appreciated.
