Emacs and C programming

Emacs and C programming

[Co$t@ntino]

Hi,
I add this line in my .emacs file:

(define-key c-mode-base-map "\C-m' newline-and-indent)

To make RET (newline, C-m) equivalent to LFD (newline and indent, C-j).

But when start Emacs says: "Symbol's value as variable is void: 
c-mode-base-map".
How could I fix it?

Thanks, Costantino


P.S.Running Emacs22 on Debian Sid.

(eval-after-load 'cc-mode
  '(define-key c-mode-base-map "\C-n" 'newline-and-indent))

Surely, because c-mode has not been loaded yet.

Use a hook to set the keybinding, e.g.

(add-hook 'c-mode-common-hook
	  (lambda ()
	    (define-key c-mode-base-map "\C-m" 'newline-and-indent)))

does the trick for me.  See also the Emacs manual,
(Info "(emacs)Hooks").

Cheers,
       Sven

(require 'cc-mode) ?
