錯誤C2039：&#39;serialize&#39;：不是&#39;boost :: units :: quantity的成員 <boost::units::si::electric_potential,double> &#39;

Question

如何將類型為electric_potential和double的地圖序列化？ 在我的代碼中，我放置了以下標頭：

#include <boost/serialization/complex.hpp>
#include <boost/serialization/map.hpp>
#include <boost/units/physical_dimensions/electric_potential.hpp>

template<class Archive, class T> 
static void serialize( Archive & ar, T & t, const unsigned int file_version ){ 
  t.serialize(ar, file_version); 
}
extern "C++" class Data_substation_AC2 : public Data_OG
{
private:
friend class boost::serialization::access;
template<class Archive>
void serialize(Archive & ar, const unsigned int version) {
    ar & BOOST_SERIALIZATION_BASE_OBJECT_NVP(Data_OG);
    ar & BOOST_SERIALIZATION_NVP(_primary_voltage);
    ar & BOOST_SERIALIZATION_NVP(_secondary_voltage);
    ar & BOOST_SERIALIZATION_NVP(_impedance1);
    ar & BOOST_SERIALIZATION_NVP(_impedance2);
    ar & BOOST_SERIALIZATION_NVP(_location);
}
std::string                                                   _name;        
bu::quantity<si::electric_potential>                          _primary_voltage;
bu::quantity<si::electric_potential>                          _secondary_voltage;
bu::quantity<si::resistance, std::complex<double>>            _impedance1;
bu::quantity<si::resistance, std::complex<double>>            _impedance2;
Data_location                                                 _location;     

我嘗試了所有標頭，但仍然遇到此錯誤：

error C2039: 'serialize' : is not a member of 'boost::units::
quantity<boost::units::si::electric_potential,double>'

我正在尋找解決此問題的最簡單方法。 感謝這張照片中的代碼，當我使用electrical_potential類型時

我看不出可能是什么問題。 您沒有顯示完整的，獨立的示例，這意味着我無法幫助您解決問題，除非通過展示如何使它起作用而做：
