Question

#include <boost/locale/encoding.hpp>
int main()
{
    const std::string strutf8("你好，世界");
    std::wstring wtrutf16 = boost::locale::conv::to_utf<wchar_t>(strutf8, "UTF-8");

    return 0;
}

这是我的代码，我想在我的项目中使用boost.locale lib在centos 7 64位系统上，我使用./bootstrap和./b2编译boost库，我的工作正常，除了我的静态链接libboost_locale.a ，我使用以下命令在控制台中编译：

g++ -o locale locale.cpp -static -L ~/Downloads/boost_1_57_0/stage/lib -lboost_system -lboost_filesystem -lboost_locale

gcc显示如下错误：

                          ....

我不知道发生了什么，我尝试安装libiconv.a，但我没有工作。所以，anynoe会告诉我如何解决这个问题。

＆＃34;未定义参考＆＃34;之后的符号名称属于ICU4C。看起来您在编译Boost Locale时选择使用ICU4C。

有两种解决方案：

添加用于关联ICU4C库的参数，请访问How To Use ICU了解详情。
重建Boost Locale，设置boost.locale.icu = off

提升静态链接boost.locale错误
