我在 Embarcadero Berlin 10.1 中创建了一个简单的控制台应用程序，选择了 32 位 clang 编译器，并从boost 文档中的此处复制了一些代码。

这是完整的代码

#pragma hdrstop
#pragma argsused

#ifdef _WIN32
#include <tchar.h>
#else
  typedef char _TCHAR;
  #define _tmain main
#endif

#include <stdio.h>

#include <boost/locale.hpp>

int _tmain(int argc, _TCHAR* argv[]) 
{
    using namespace boost::locale;
    using namespace std;
    generator gen;
    locale loc=gen("");
    // Create system default locale

    locale::global(loc);
    // Make it system global

    cout.imbue(loc);
    // Set as default locale for output

    cout <<format("Today {1,date} at {1,time} we had run our first localization example") % time(0)
      <<endl;

    cout<<"This is how we show numbers in this locale "<<as::number << 103.34 <<endl;
    cout<<"This is how we show currency in this locale "<<as::currency << 103.34 <<endl;
    cout<<"This is typical date in the locale "<<as::date << std::time(0) <<endl;
    cout<<"This is typical time in the locale "<<as::time << std::time(0) <<endl;
    cout<<"This is upper case "<<to_upper("Hello World!")<<endl;
    cout<<"This is lower case "<<to_lower("Hello World!")<<endl;
    cout<<"This is title case "<<to_title("Hello World!")<<endl;
    cout<<"This is fold case "<<fold_case("Hello World!")<<endl;

    return 0;
}

但我得到一些链接器错误：

[ilink32 Error] Error: Unresolved external 'boost::system::generic_category()' referenced from C:\PROGRAM FILES (X86)\EMBARCADERO\STUDIO\18.0\LIB\WIN32C\RELEASE\LIBBOOST_LOCALE-BCB32C-MT-SD-1_55.LIB|generator

前两个我可以通过手动将 libboost_locale-bcb32c-MT-SD-1_55.lib 添加到项目中来修复，这是我对 boost 的理解和经验，它不应该真的需要手动链接，但我不介意这一点。然而，最后4个，我完全不确定。它看起来与语言环境后端有关（它不是 ICU 与 Embarcadero 提供的提升吗？）

有人有建议吗？

你的问题对我来说很有趣。所以我创建了一个新项目并将您的代码复制到其中，果然问题再次出现。在做了一些研究之后，
我能够克服这个问题的唯一方法是在我的项目中添加collate.cpp和定位。我还必须在函数之前添加到我的源代码中。converter.cppnumeric.cpp$(BDSINCLUDE)\boost_1_55\libs\locale\src\win32#pragma link "libboost_system-bcb32c-mt-sd-1_55.lib"main
