c++ - boost 翻译: po file not work

Question

我曾使用 boost::locale 制作多语言 exe，但它不起作用。exe 总是输出“Hello World”。怎么输出“您好”？

我使用了 http://www.boost.org/doc/libs/1_53_0/libs/locale/doc/html/messages_formatting.html 中的示例代码

    #include <boost/locale.hpp>
    #include <iostream>

    using namespace std;
    using namespace boost::locale;

    int main()
    {
        generator gen;

        // Specify location of dictionaries
        gen.add_messages_path(".");
        gen.add_messages_domain("hello");

        // Generate locales and imbue them to iostream
        locale::global(gen(""));
        cout.imbue(locale());

        // Display a message using current system locale
        cout << translate("Hello World") << endl;
    }

并制作一个po文件和一个mo文件。Po文件是:

# SOME DESCRIPTIVE TITLE.
# Copyright (C) YEAR THE PACKAGE'S COPYRIGHT HOLDER
# This file is distributed under the same license as the PACKAGE package.
# FIRST AUTHOR <EMAIL@ADDRESS>, YEAR.

msgstr "您好"

我也是从 boost_locale 开始的，这是我如何让它工作的......

1. 首先确保您的 .mo 文件的命名与您引用的域完全相同，在本例中为 hello.mo

2. 将 .mo 文件放入正确的文件结构中，例如，如果您尝试翻译成西类牙语，这将是 ./es_ES/LC_MESSAGES/hello.mo

3. 确保像这样实例化全局语言环境，locale::global(gen("es_ES.UTF-8"));

希望这对您有所帮助。
