c++ - 带Boost的XML序列化( '.serialize'的左侧必须具有class/struct/union)

我有两个类BaseTolerance和ImageProcessingTask。我收到错误消息:“错误C2228:.serialize的左侧必须具有class / struct / union”。

如果行(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);
};

最佳答案

错误实际上来自尝试序列化char *，一旦我看到，我就按照Direct boost serialization to char array的建议切换到std::string。
