Symbol's function definition is void

Symbol's function definition is void

[Lalit Saraswat]

Hi All,

When i try to save something in emacs, i am getting following error:
"Symbol's function definition is void: auto-update-file-header"

more detailed log:
#########
("C:\\emacs-22.3\\bin\\emacs.exe")

earlier it was working fine. i tried to add default header in emacs using
header2.el file. after that i am consistently facing this issue.

I also restored .emacs in previous working version, but this issue is still
there.

Please help in resolving this issue.

Sorry for your trouble.  If you use `auto-update-file-header' on a hook
that gets run then you also need to load the library that defines it: header2.el.

Put one of these in your .emacs: (require 'header2)
or (autoload 'auto-update-file-header "header2"
             "Update file header if file is modified.")

I've added this info to the file header of header2.el now.  Thx.

thanks adams. due to this issue i was not able to use emacs on my laptop.

few more questions on using this file.
1) i m not sure where to store this file. or how to add header2.el file
path in .emacs.
2) i want to add this header in different kind of file like
.c/.vhd/.v/.cpf/.upf. or in other word i want to use same header for any
kind of file. what should i add in .emacs.

Thanks and Regards,
Lalit

Add its location to your option `load-path'.

 M-x customize-option load-path RET

or put this in your init file:

 (add-to-list 'load-path "YOUR LOCATION OF HEADER2.EL")

where the string is the directory where header2.el is located.

As the file Commentary says:

;; To have Emacs add a file header whenever you create a new file in
;; some mode, put this in your init file (~/.emacs):
;;
;;   (autoload 'auto-make-header "header2")
;;   (add-hook 'emacs-lisp-mode-hook 'auto-make-header)
;;   (add-hook 'c-mode-common-hook   'auto-make-header)
;;   ...

`c-mode-common-hook' should take care of your .c files.
For the other files, figure out what major mode Emacs uses for each
of them, and then use (add-hook 'THAT_MODE 'auto-make-header).
