You need to bind the language domain somewhere during the
initialisation phase (usually in main()):

bindtextdomain(GETTEXT_PACKAGE, PACKAGE_LOCALE_DIR);
bind_textdomain_codeset(GETTEXT_PACKAGE, "UTF-8");
textdomain(GETTEXT_PACKAGE);

Next you need to create and install a message cataloge. This
involves to extract the translatable strings from the source
and translate it in the target languages. The gettext tools
are used for this. See*: http://www.async.com.br/~kiko/gettext.html

If you use autotools, there is intltoolize and autopoint to
initialize the build framework and update the messages.
