Question

当我尝试构建/运行boost-Serialization示例代码程序时，我遇到了错误，我无法解决，代码来自boost序列化教程，所以我不知道认为这是错的。我使用的是NetBeans 8.0.2 IDE和Boost Library Version 1.58.0。代码：

#include <fstream>

// include headers that implement a archive in simple text format
//#include <boost/archive/text_oarchive.hpp>
//#include <boost/archive/text_iarchive.hpp>
#include "../boost/archive/text_oarchive.hpp"
#include "../boost/archive/text_iarchive.hpp"

/////////////////////////////////////////////////////////////
// gps coordinate
//
// illustrates serialization for a simple type
//
class gps_position
{
private:
    friend class boost::serialization::access;
    // When the class Archive corresponds to an output archive, the
    // & operator is defined similar to <<.  Likewise, when the class Archive
    // is a type of input archive the & operator is defined similar to >>.
    template<class Archive>
    void serialize(Archive & ar, const unsigned int version)
    {
        ar & degrees;
        ar & minutes;
        ar & seconds;
    }
    int degrees;
    int minutes;
    float seconds;
public:
    gps_position(){};
    gps_position(int d, int m, float s) :
        degrees(d), minutes(m), seconds(s)
    {}
};

int main() {
    // create and open a character archive for output
    std::ofstream ofs("filename");

    // create class instance
    const gps_position g(35, 59, 24.567f);

    // save data to archive
    {
        boost::archive::text_oarchive oa(ofs);
        // write class instance to archive
        oa << g;
        // archive and stream closed when destructors are called
    }

    // ... some time later restore the class instance to its orginal state
    gps_position newg;
    {
        // create and open an archive for input
        std::ifstream ifs("filename");
        boost::archive::text_iarchive ia(ifs);
        // read class state from archive
        ia >> newg;
        // archive and stream closed when destructors are called
    }
    return 0;
}

现在出现错误消息：

您需要关联libboost_serialization：

g++  main.cpp -lboost_serialization

Boost Serialization示例错误：找不到架构x86_64的符号
