Question

我有两个类BaseTolerance和ImageProcessingTask。我收到错误消息：＆＃39;错误C2228：左边的＆＃39; .serialize＆＃39;必须有class / struct / union＆＃39;。

如果该行（在ImageProcessingTask中）

        ar & make_nvp("ToleranceToMeasure", tolerance_to_measure_);

被注释掉，错误消息消失。

#include <boost/archive/xml_oarchive.hpp>

class BaseTolerance
{
private:
    friend class boost::serialization::access;

template<class Archive>
void serialize(Archive & ar, const unsigned int version)
{
    using boost::serialization::make_nvp;
    ar & make_nvp("ToleranceName", tolerance_name_);
}

    char* tolerance_name_;
    public:
    BaseTolerance();
    ~BaseTolerance();

    char* GetToleranceName();
    void SetToleranceName(char* name);
};

和

#include "GeometricTolerance.h"

class ImageProcessingTask
{
    BaseTolerance *tolerance_to_measure_;

    friend class boost::serialization::access;

    template<class Archive>
    void serialize(Archive & ar, const unsigned int version)
    {
        using boost::serialization::make_nvp;               
        ar & make_nvp("ToleranceToMeasure", tolerance_to_measure_);
    }
public:
    ImageProcessingTask();
    ~ImageProcessingTask();

    BaseTolerance *GetToleranceToMeasure();
    void SetToleranceToMeasure(BaseTolerance *tolerance);
};

错误实际上来自于尝试序列化char *，一旦我看到它，我切换到std :: string，如Direct boost serialization to char array

中提出的那样

带序列的XML序列化（＆＃39; .serialize＆＃39;左边必须有class / struct / union）
