boost翻譯：po文件不起作用

Question

我用boost :: locale製作了一個多語言exe文件，但它不起作用。 該exe文件總是輸出「Hello World」。 如何輸出「您好」？

我使用的示例代碼http://www.boost.org/doc/libs/1_53_0/libs/locale/doc/html/messages_formatting.html

#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; 
    } 

並做好PO文件和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. 
# 
msgid "" 
msgstr ""

#: main.cpp:21 
msgid "Hello World" 
msgstr "您好"

林年初boost_locale過，這是我如何使它工作...

1. 首先確保你的.mo文件正是命名爲域的闖民宅到，在這種情況下hello.mo

2. 把文件的.mo到正確的文件結構，例如，如果你想翻譯成西班牙語，這將是./es_ES/LC_MESSAGES/hello.mo

3. 請確保你實例化了這樣的全局語言環境， locale :: global（gen（「es_ES.UTF-8」））;

希望這會有所幫助。
