I am trying to write a program that prints an English message in French based on locale.
I wrote the following sample code:
#include <stdio.h>
#include <libintl.h>
#include <locale.h>
int main()
{
char *str = setlocale(LC_ALL, "fr_FR.UTF-8");
if(str == NULL)
printf("setlocale() cannot be honored");
else
printf("setlocale() return = %s \n", str);
bindtextdomain("helloworld","/usr/share/locale");
textdomain("helloworld");
printf("%s", gettext("Hello!\n"));
return 0;
}
I checked the file /usr/share/i18n/SUPPORTED
and can see fr
is there:
fr_FR.UTF-8 UTF-8
fr_FR ISO-8859-1
fr_FR@euro ISO-8859-15
I also tried running sudo locale-gen fr-FR.UTF-8
. When I run locale
on the command line, I see:
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
When I run my program, setlocale()
returns NULL
. Can anyone tell what I'm missing ?
Edit
When trying to for zh-CN
, I also checked the contents of directory /usr/share/locale/zh-CN/LC_MESSAGES
. The following listing appears:
apt.mo gnome-panel-3.0.mo iso_639.mo
debconf.mo iso_15924.mo language-selector.mo
dpkg.mo iso_3166_2.mo libapt-inst1.4.mo
e2fsprogs.mo iso_3166.mo libapt-pkg4.12.mo
example-content.mo iso_4217.mo update-notifier.mo
ghex-3.0.mo iso_639_3.mo xdg-user-dirs.mo
If locale -a
doesn't show fr_FR locale, you do not have one installed on your system.
The best/easiest way to do it may slightly depends on the distro. This topic answers your question: https://askubuntu.com/questions/76013/how-do-i-add-locale-to-ubuntu-server
