The error code refers to Print.hpp line 51 first input.// MyData.hpp filetypedef struct tagMyData{ std::string id; std::string name; boost::shared_ptr ptMydata;public: MyData(void); MyData(const parameter_strings& parms); virtual ~MyData(void);private: friend class boost::serialization::access; template void serialize(Archive &ar, const unsigned int version) { ar &id; ar &name; ar &ptMydata; ar &version; }} MyData; // MyData.cpp file MyData::MyData(void) { } MyData::~MyData(void) { } MyData::MyData(const parameter_strings & parms) { // implementation aprt } BOOST_CLASS_EXPORT_IMPLEMENT(MyData); BOOST_CLASS_IMPLEMENTATION(MyData,boost::serialization::object_serializable); BOOST_CLASS_TRACKING(MyData,boost::serialization::track_selectively); 这篇关于在Boost序列化中，共享指针不起作用..它给出了错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！ 08-11 09:37
