RE: `_' undeclared (first use this function) ??

[<martyn 2 russell bt com>]

Hi,

Basically anything that has _("some string") means that "some string"
can be translated into language "x", given that someone has translated
it for language "x" and that language "x" is specified/set in the
environment before running the code.

_() is a function supplied by GNU gettext, for more information see:
http://www.gnu.org/software/gettext/manual/html_mono/gettext.html#SEC6

This is also supported by Gnome, for developer information:
http://developer.gnome.org/arch/i18n/

For languages supported by gnome:
http://www.gnome.org/i18n/

If you use libgnome in your build and #include <libgnome/gnome-i18n.h>
it should fix this problem.

If you do not use libgnome and do not want to use it, set up your own
pre-processor definition to get around it:

        #define _(String) (String)

I'm sure GNU's gettext is used by Glib (which is used by GTK) and so
libgnome need not be utilised at all, but I haven't looked into this.

Regards,
Martyn
