【问题描述】：

我试图找到一个很好的例子来说明如何使用这些二进制宽字符版本的 boost 的序列化内容。我拼凑了一些代码来尝试让它工作，但不幸的是，在尝试编译它时，我遇到了链接器错误。

这是我的代码，以防我做错了什么：

    #include <cstdlib>
    #include <iostream>
    #include <fstream>
    #include <string>
    #include <vector>

    #include <boost/archive/binary_woarchive.hpp>
    #include <boost/archive/binary_wiarchive.hpp>

    class testClass
    {
    public:
        testClass()
        {
        }
        testClass(const int intInput, const std::wstring stringInput, const float floatInput01, const float floatInput02)
        {
            ourString = stringInput;
            testInt = intInput;
            testFloat01 = floatInput01;
            testFloat02 = floatInput02;
        }
        ~testClass()
        {}

        int testInt;
        std::wstring ourString;
        float testFloat01;
        float testFloat02;

        int ReturnTestInt()
        {
            return testInt;
        }

        float RandomStuff()
        {
            float alpha01 = 26.9;
            alpha01 /= 2;
            return alpha01;
        }

    private:
        friend class boost::serialization::access;
        template<class Archive>
        void serialize(Archive &ar, const unsigned int version)
        {
            ar &testInt;
            ar &ourString;
            ar &testFloat01;
            ar &testFloat02;
        }
    };

    int main()
    {
        std::vector<const testClass> objectStorage;


        objectStorage.push_back(testClass(1, L"test\0", 9.14f, 6.662f));
        objectStorage.push_back(testClass(2, L"temp\0", 0.29f, 3.331f));
        objectStorage.push_back(testClass(3, L"then\0", 2.47f, 8.888f));


        testClass testReceivedObject;
        std::ifstream::pos_type size;

        std::wofstream myFile;
        boost::archive::binary_woarchive outputArchive(myFile);
        myFile.open("Example.dat", std::ios::out | std::ios::binary);

        if(myFile.is_open() && myFile.good())
        {
            std::cout<<"File opening successfully completed."<<std::endl;
            unsigned int storageSize = objectStorage.size();

            myFile.write(reinterpret_cast<wchar_t*>(&storageSize), (sizeof(unsigned int)));

            for(int i = 0; i < objectStorage.size(); i++)
            {

            }

            myFile.write(reinterpret_cast<char*>(&objectStorage[1]), (sizeof(testClass)));
            myFile.write(reinterpret_cast<char*>(&objectStorage[2]), (sizeof(testClass)));
        */
        }
        else
        {
            std::cout<<"File opening NOT successfully completed."<<std::endl;
        }
        myFile.close();

        std::wifstream myFileInput;
        boost::archive::binary_wiarchive inputArchive(myFileInput);
        myFileInput.open("Example.dat", std::ios::in | std::ios::binary | std::ios::ate);

        if(myFileInput.is_open() && myFileInput.good())
        {
            std::cout<<"File opening successfully completed.  Again."<<std::endl;

            std::cout<<"READ:"<<std::endl;
            size = myFileInput.tellg();
            unsigned int numberOfObjects = 0;
            myFileInput.seekg(0, std::ios::beg);            
myFileInput.read(reinterpret_cast<wchar_t *>(&numberOfObjects), sizeof(unsigned int));
            for(int i = 0; i < numberOfObjects; i++)
            {
                objectStorage.resize(objectStorage.size()+1);
                inputArchive>>objectStorage[i];
                //myFileInput.read(reinterpret_cast<wchar_t *>(&objectStorage[i])/*(&testReceivedObject)*/, sizeof(testClass));
            }
            std::cout<<std::endl<<"END."<<std::endl;
        }
        else
        {
            std::cout<<"Something has gone disasterously wrong."<<std::endl;
        }
        myFileInput.close();

        for(int i = 0; i < objectStorage.size(); i++)
        {
            std::wcout<<objectStorage[i].ourString<<std::endl;
        }
        return 0;
    }

以下是错误：

我们将不胜感激有关了解问题所在以及如何解决问题的建议。

【问题讨论】：

要清楚，您实际上是否链接到 Boost.Serialization？狭窄的溪流对你有用吗？您是自己构建 Boost 还是使用预构建的二进制文件？
我不久前安装了它（Boost），我相信我使用了 Windows 安装程序，这显然意味着它们已经构建了？无论哪种方式，boost_1_47_0\stage\lib 目录中都有很多 .lib 文件。另外，您能详细说明一下窄流是什么意思吗？
您下载的版本是用您正在使用的exact 版本的VC++ 构建的？而且您没有使用/Zc:wchar_t- 进行编译？关于狭窄的溪流，对不起，那是一个错字；我的意思是，窄 strings 对你有用吗？即std::string 和binary_oarchive 和binary_oarchive？或者这绝对是特定于宽字符的？
binary_oarchive 和 binary_iarchive 工作。事实上，我使用了上面粘贴的代码，并对普通字符进行了一些必要的更改。至于/Z这个东西，我看了一下VS2010中项目的命令行部分，/Zc:wchar_t就在那里。
我刚刚使用您的代码和 Boost.Serialization 1.49.0 的干净构建在本地进行了测试——我可以重现该问题。我怀疑这是 Boost.Serialization 中的一个错误，而且我认为 Robert 没有阅读 SO，所以最好的办法是在 Boost Users mailing list 上发布您的问题（他确实阅读过）。

标签： c++ linker-errors boost-serialization wofstream

【解决方案1】：

原来boost/archive/binary_woarchive.hpp和boost/archive/binary_wiarchive.hpp是多余的。

即使对于包含宽字符变量的类实例，boost/archive/binary_oarchive.hpp 和 boost/archive/binary_iarchive.hpp 也能正常工作！

我希望这些信息对某人有所帮助。
