setlocale doesn't change the language. Why?

[Joerg Desch <news@jdesch.de>]

Hi.

I'm running Debian Squezze on a small AMD Geode based embedded PC. I need 
to use the gettext library independend from the system wide language 
settings to toggle the language for strings only.

On my PC, the test runs within a chroot environment als expected. On the 
embedded PC, it doesn't switch the language with setlocale().

Please can some help me?

Here's the code snippet I use.


#define PACKAGE "sample2"
#define _(String) gettext (String)

int main()
{
    printf("Current LOCALE: '%s'\n",setlocale(LC_ALL,0));
    bindtextdomain(PACKAGE,"./locale");
    textdomain(PACKAGE);

    printf("Switch to 'en'\n");
    setlocale(LC_MESSAGES,"en_EN.UTF8");
    printf("New LOCALE: '%s'\n",setlocale(LC_MESSAGES,0));
    printf(_("Hello World\n"));

    printf("Switch to 'de'\n");
    setlocale(LC_MESSAGES,"de_DE");
    printf("New LOCALE: '%s'\n",setlocale(LC_MESSAGES,0));
    printf(_("Hello World\n"));

    printf("Switch to 'de.utf8'\n");
    setlocale(LC_MESSAGES,"de_DE.UTF8");
    printf("New LOCALE: '%s'\n",setlocale(LC_MESSAGES,0));
    printf(_("Hello World\n"));

    return 0;
}


The output in the chroot is:
$ ./sample2
Current LOCALE: 'C'
Switch to 'en'
New LOCALE: 'C'
Hello World
Switch to 'de'
New LOCALE: 'C'
Hello World
Switch to 'de.utf8'
New LOCALE: 'de_DE.UTF8'
Hallo Welt

And on the embedded PC:
# ./sample2
Current LOCALE: 'C'
Switch to 'en'
New LOCALE: 'C'
Hello World
Switch to 'de'
New LOCALE: 'C'
Hello World
Switch to 'de.utf8'
New LOCALE: 'C'
Hello World
