Subject: Science to suppress compiler warnings
Date: Wed, 03 Jun 2009 01:08:22 +0200 [thread overview]
Message-ID: <87fxeigro9.wl%xma@gnu.org> (raw)
Hi,
Elisp manual at "Compiler Errors" section (16.6) says we should
conditionalize variable use with a boundp test (same thing for
undefined function) but I find it very unpractical.
I thought (probably was wrong) that:
(eval-when-compile (defvar foo nil))
would do the trick. Is it the correct way to avoid warnings ?
Also while at it, here is what I got when compiling an old
package:
records.el:931:49:Warning: reference to free variable
`records-link-menu-map'
In records-mode:
records.el:1066:23:Warning: assignment to free variable
`records-link-menu-map'
What is the difference between these two warnings exactly ?
Adding a defvar at the right place fixed that but to feed my
curiosity.
Regards,
Xavier
