Question

我是c ++的新手，刚刚发现了升级库。在我用来学习c ++的小程序中（我使用MSVC 2015），我想使用boost序列化来保存/加载我的播放器类。我在课堂上实现了所需的功能，如下所示：

Player.h

class Player
{
public:
    Player();
private:
    friend class boost::serialization::access;
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version);
    int race; //For now im only attempting to serialize one variable to make it as simple as possible.
};

Player.cpp

using namespace std;
Player::Player()
{
    race = -1; //Default value for race.
}
//Serialisation: 
template<class Archive>
void Player::serialize(Archive & ar, const unsigned int version) {
    ar & race;
}
...Other unnecessary functions not listed

Main.cpp的

void savePlayer() { //Called when player is to be saved.
    string filename;
    filename = p.getName() + "_" + getTime();
    {
        std::ofstream ofs(filename);
        boost::archive::binary_oarchive oa(ofs);
        oa << p; //Removing this line stops the error from occouring for some reason.
    }
}

编译时出现以下错误：

Main.obj : error LNK2019: unresolved external symbol "private: void __thiscall Player::serialize<class boost::archive::binary_oarchive>(class boost::archive::binary_oarchive &,unsigned int)" (??$serialize@Vbinary_oarchive@archive@boost@@@Player@@AAEXAAVbinary_oarchive@archive@boost@@I@Z) referenced in function "public: static void __cdecl boost::serialization::access::serialize<class boost::archive::binary_oarchive,class Player>(class boost::archive::binary_oarchive &,class Player &,unsigned int)" (??$serialize@Vbinary_oarchive@archive@boost@@VPlayer@@@access@serialization@boost@@SAXAAVbinary_oarchive@archive@2@AAVPlayer@@I@Z)

我已经在网上浏览了几个小时寻找解决方案，我能找到的最接近的是：http://boost.2283326.n4.nabble.com/Help-with-Visual-Studio-settings-for-Boost-Serialization-td3072458.html 找到这个问题的解决方案真的很好，因为在线没有明显的解决方案。

先谢谢 - Yepadee。
