compiler warning "the function X might not be defined at runtime"

compiler warning "the function X might not be defined at runtime"

[Samuel Wales]

What more needs to be done to get rid of that warning?

Thanks.

I believe that, starting with Emacs 23, you can use `declare-function' to tell
the byte-compiler which library the function is defined in (and what its
arguments are). See the Elisp manual, node Declaring Functions.

Thanks.

I should have mentioned that I use emacs 22, so I can't use
declare-function, because it says it does nothing.

I am curious why that function (only).

How are you calling scroll-lock-mode and how are you compiling the file?

I don't get any warnings with M-x byte-compile-file in emacs 23.2,
started with -Q,  on this file:

-------- foo.el --------
(defun foo ()
   (scroll-lock-mode 0))
-------- foo.el --------

I meant emacs 22.3 of course.

I am not calling it except as above and with a similar function with
the argument 1 instead of 0.

Also this, but it should be irrelevant.

(define-key global-map [(control shift up)]
  'scroll-lock-previous-line)
(define-key global-map [(control shift down)] 'scroll-lock-next-line)

Same as you.

GNU Emacs 22.2.1 Carbon.

Thanks.

So is X (in your subject) scroll-lock-mode, scroll-lock-previous-line,
or scroll-lock-next-line?

If X is a scroll-lock-*-line function, do those define-key forms occur
at top level, or within a top level defun, or where?
