Until now, I'm really happy with the toolchain around gettext. IMO using 
poedit for external translation teams is a good way to go.

I've been fighting with that myself the other day.

echo $LANGUAGE?

If you don't want that, you need to

putenv("LANGUAGE=");

This is a GNU extension which does have some use, but it *breaks* in some
non-wrong use cases.

SOLVED: setlocale doesn't change the language. Why?

The solution was simple. While "dpkg-reconfigure locales" only allows the 
selection of one language. I thought that this should be the default. But 
instead all not selected entries are not possible.

So the solution was to enable all languages I need to select in my code. 
After this, my sample works as expected.

Thanks for your help.

It probably means that only locales actually created (default or not) on 
the system works.

An alternative to installing package "locales" and enabling locales via 
debconf is to install package "locales-all".

You are right. But this selection isn't needed. ;-)

I've already changed this in my current sample.

OK, the package "locales" wasn't installed by the embedded distribution.

After installing locales and selecting "en_GB.UTF8" as default, my sample 
still not use "de_DE.UTF8". So I've called dpkg-reconfigure locales and
chosen de_DE.UTF8 as a default. No I can switch to it.

But does that mean, that I only can switch between the default language 
and none? It enhanced the sample to try es_ES.UTF8 without a reconfigure 
locales and it doesn't work.

There is no such locale.  Perhaps you meant en_GB.UTF-8 or en_US.UTF-8.

Also 'man locale'

setlocale doesn't change the language. Why?

2015-03-12 Thread Joerg Desch 
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

No. I expect the same output as shown by the other example. I expected 
that either "de_DE" or "de_DE.UTF8" should fit.

How can I check which locales are available?

Yes. So the example shows that neither of my calls to setlocale() result 
in the expected language. The big question is why? The sample works on my 
Desktop (Debian Wheezy) and in the chroot (Debian Squeeze) environment.

You don't have 'de.utf8' locale on this system.
setlocale(3) has a return value which you should check if you are
interested whether it succeeded.
