There are not different versions of Linux for different languages.
Linux is fully internationalised, so one system can handle *all*
languages.
Internationalisation takes place at the level of the C library, where
locales are used to define program behaviour in different localities,
which is set by environment variables. This controls the output
character set, sorting and collation, date and monetary formatting
etc. On top of this gettext is commonly-used to translate program
output into the language specifed by the locale.
What locale and charset are you using:
$locale
$locale -k charmap

Make sure the Glade interface is created with all the translatable
strings written in English (not required, but it will make things
simpler). Make sure you restrict yourself to US-ASCII characters
(again, not required, but it makes things simpler).
You now need to run xgettext to extract the translatable strings and
put them in a .pot file. If you've properly gettextized your source
tree, edit po/POTFILES.in and add the message files you asked Glade to
create (1 per .glade file).
Next, copy the .pot file po/$PACKAGE.pot to e.g. po/zh_HK.po. This
file is the one which translates the English strings to Chinese. Make
sure you set the encoding to UTF-8 (not required, but it makes things
easier since GTK+ uses UTF-8 throughout). Edit this file with
GTranslator or Emacs po-mode (I prefer the latter). Add the
translation zh_CN to the ALL_LINGUAS variable in configure.ac.
Build and install; you should have a po/zh_HK.mo file installed under
/usr/share/locale/zh_HK/LC_MESSAGES/, which will be installed if
LANG=zh_HK in your environment.
If you are unsure why I suggested these steps, check out the GNU
gettext manual.
Regards,
Roger
