부스트 :: serialize - 개체의 벡터를 deserialize 하시겠습니까?

Question

최근에는 객체 벡터가 포함 된 클래스를 직렬화하려고했습니다. #include <boost/serialization/vector.hpp>을 포함 시키면 간단한 & 연산자로 처리 할 수 ​​있습니다. 불행하게도, 컴파일러는 직렬화 코드를 작성하기로 동의하지만, 역 직렬화 테스트 케이스를 컴파일 할 수는 없습니다. 거기에 무슨 문제가 있을까요?

serialize 멤버 함수 const 안 : 아래

#include <boost/archive/text_oarchive.hpp> 
#include <boost/archive/text_iarchive.hpp> 
#include <boost/serialization/vector.hpp> 

#include <fstream> 

class A 
{ 
     friend class boost::serialization::access; 
     template<class Archive> 
       void serialize(Archive & ar, const unsigned int version) const 
       { 
       } 
}; 

class B 
{ 

     friend class boost::serialization::access; 

     template<class Archive> 
       void serialize(Archive & ar, const unsigned int version) const 
       { 
         ar & a; 
       } 

     std::vector<A> a; 
}; 

int main() 
{ 
     std::ifstream ifs("filename"); 
     boost::archive::text_iarchive ia(ifs); 
     B b; 
     ia >> b; 

} 

컴파일러의 오류입니다. 그것은 직렬화하는데 사용되지만, 역 직렬화에도 사용됩니다.
