[英]Testing locale on Ubuntu using setlocale() and gettext()
I am trying to write a program that prints an English message in French based on locale. 我正在尝试编写一个根据语言环境以法语打印英文消息的程序。
I wrote the following sample code: 我编写了以下示例代码:
#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: 我检查了文件
/usr/share/i18n/SUPPORTED
,可以看到fr
在那里:
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
. 我也尝试运行
sudo locale-gen fr-FR.UTF-8
。 When I run locale
on the command line, I see: 在命令行上运行
locale
时,我看到:
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
. 当我运行程序时,
setlocale()
返回NULL
。 Can anyone tell what I'm missing ? 谁能告诉我我所缺少的吗?

When trying to for zh-CN
, I also checked the contents of directory /usr/share/locale/zh-CN/LC_MESSAGES
. 尝试使用
zh-CN
,我还检查了目录/usr/share/locale/zh-CN/LC_MESSAGES
。 The following listing appears: 出现以下清单:
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. 如果
locale -a
没有显示fr_FR语言环境,则您的系统上没有安装一个语言环境。
The best/easiest way to do it may slightly depends on the distro. 最好/最简单的方法可能会稍微取决于发行版。 This topic answers your question: https://askubuntu.com/questions/76013/how-do-i-add-locale-to-ubuntu-server
