(Solved) Gettext and C

[RSH]

Hi.

I have a little knowledge of C and almost each little tool I've created using C, was based on a C example I've got from 01micko.

By now I need always to build two versions, one for DE and one for EN.

So I need to learn how to use gettext in C.

Can anybody show me a quick example of how to use gettext in C, or at least point me to some C source codes wherein gettext is used, so that I can examine the code?

Thanks,

RSH

Hi RSH

Take a look at network_tray and some of the others that Barry originally wrote. rodin.s gettext'd them, I think with help of L18L. Don't pay too much attention to the actual C code, it needs work, but you can see the _(bla) format where the underscore flags the string to be translated. There is also relevant stuff in the 'compile' script(s).

http://distro.ibiblio.org/puppylinux/sources/ .. which is quite incomplete but there is network_tray under /n/ and a few others.

Hi 01micko.

Thanks for the reply.

I have examined network_tray and included the necessary parts into my C code file. Gettext is installed and works - checked this by running Screeny, which appears in DE.

Though my C Application won't show in DE:

Here is how I did compile:

Code: Select all

lxterminal -e gcc -o refresh_my_desktop refresh_my_desktop.c `pkg-config --libs --cflags gtk+-2.0`
xgettext --keyword="_" refresh_my_desktop.c -o refresh_my_desktop.pot

Content of the created .pot (.mo) file:

"Content-Type: text/plain; charset=CHARSET\n"
"Content-Transfer-Encoding: 8bit\n"

#: refresh_my_desktop.c:55
msgid "Refresh the Desktop"
msgstr "Arbeitsfläche aktualisieren"

Note: msgstr "Arbeitsfläche aktualisieren" was edited after .pot creation, then made a .mo file from this and copied into /usr/share/locale/de/LC_MESSAGES.

Though the tool-tip still shows EN message, Refresh the Desktop.

What am I doing wrong here???

What am I doing wrong here???

I dunno, but it works fine here.
Make sure

• you have de.po created from the .pot
  that UTF-8 is set for charset=
  compile with msgfmt de.po -o refresh_my_desktop.mo

(I just changed icon for my convenience)

[RSH]

Make sure

you have de.po created from the .pot
that UTF-8 is set for charset=
compile with msgfmt de.po -o refresh_my_desktop.mo

UTF-8 was the missing point.

Works now over here as well.

So I'm prepared now...

Thank you very much!

I have tried to follow your guidelines, but I still fail to translate the pMusic trayapp correct
- built pot file with the command xgettext --keyword="_" pmusic_trayapp.c -o pmusic_trayapp.pot
- Translated the pot file to nb_NO.po
- Set charset=UTF-8 in po file
- Compiled with msgfmt nb_NO.po -o pmusic_trayapp.mo
- Placed the pmusic_trayapp.mo in /usr/share/locale/nb_NO/LC_MESSAGES/pmusic_trayapp.mo
- set LANG, and run trayapp

The attached screenshot shows the details.


Thank you for any help

Hey Sigmund

Try LANGUAGE=... instead of LANG=....
I've learned it here: http://www.murga-linux.com/puppy/viewtopic.php?t=92929

Greetings!

Yepp!

Thank you
