錯誤C2039：'serialize'：不是'boost :: units :: quantity <boost :: units :: si :: electric_potential，double>'的成員'

Question

如何序列化類型爲electric_potential和double的映射？ ？ 在我的代碼我已經把這些標題：

#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;  

我嘗試了所有的信息，但是仍然我有這樣的錯誤：

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

我正在尋找最簡單的方式來解決這個問題。 謝謝 in this picture the code when i use the type electrical_potential

我看不清楚問題所在。你不顯示完整的，自包含的樣本，這意味着我不能幫你認識到這個問題，除了通過展示我做了什麼，使其工作：
