The following message is a courtesy copy of an article that has been posted to comp.emacs.xemacs as well. Tobias> Hi, Tobias> My problem: Tobias> When I visit a perl file in CPerl mode "Run", "Check Tobias> syntax" and all the other menu items relying on the Tobias> interpreter are disabled! Do I have to enter Tobias> /usr/bin/perl somewhere? You need mode-compile.el. This should really be part of some XEmacs package. Get it from http://www.tls.cena.fr/~boubaker/distrib/mode-compile.el or ftp://archive.cis.ohio-state.edu/pub/gnu/emacs/elisp-archive/misc/mode-co... Currently I cannot reach the latter. Hope this helps, Adrian Tobias> -- Tobias> Tobias Weber
