在自定义存档的boost序列化中出现链接器错误。

Question

我试着按照以下方法实现了自己的归档类型，以实现提升序列化。官方助推例写档案.

#include <iostream>
#include <vector>

#include <boost/serialization/nvp.hpp>
#include "boost/serialization/vector.hpp"

#include <boost/archive/detail/common_oarchive.hpp>
#include <boost/archive/detail/register_archive.hpp>

#include <boost/archive/detail/archive_serializer_map.hpp>


class complete_oarchive : public boost::archive::detail::common_oarchive<complete_oarchive>
{
    friend class boost::archive::save_access;

    template<class T>
    void save(T & t){
      std::cout << "saved data\n";
    }

public:
    void save_binary(void *address, std::size_t count){
    }
};


template class boost::archive::detail::archive_serializer_map<complete_oarchive>;
template class boost::archive::detail::common_oarchive<complete_oarchive>;
BOOST_SERIALIZATION_REGISTER_ARCHIVE(complete_oarchive)


int main(int argc, char *argv[])
{   

    std::vector<double> testVector = {1, 2, 3, 4};
    complete_oarchive oa;
    std::vector<double>* pVec = &testVector;
    oa << BOOST_SERIALIZATION_NVP(testVector);
    oa << BOOST_SERIALIZATION_NVP(pVec);

    return 0;
}

编译这个例子的时候

g++    -c -g -std=c++11 -MMD -MP -MF "build/Debug/GNU-Linux/demo.o.d" -o build/Debug/GNU-Linux/demo.o demo.cpp
g++     -o dist/Debug/GNU-Linux/serializationdemo build/Debug/GNU-Linux/demo.o -lboost_serialization

导致以下链接器错误

build/Debug/GNU-Linux/demo.o: In function `boost::archive::detail::pointer_oserializer<complete_oarchive, std::vector<double, std::allocator<double> > >::pointer_oserializer()':
/opt/tools/boost/boostRdk-1.66.0/include/boost/archive/detail/oserializer.hpp:222: undefined reference to `boost::archive::detail::archive_serializer_map<complete_oarchive>::insert(boost::archive::detail::basic_serializer const*)'
build/Debug/GNU-Linux/demo.o: In function `boost::archive::detail::pointer_oserializer<complete_oarchive, std::vector<double, std::allocator<double> > >::~pointer_oserializer()':
/opt/tools/boost/boostRdk-1.66.0/include/boost/archive/detail/oserializer.hpp:227: undefined reference to `boost::archive::detail::archive_serializer_map<complete_oarchive>::erase(boost::archive::detail::basic_serializer const*)'
collect2: error: ld returned 1 exit status 

似乎将指针序列化在

oa << BOOST_SERIALIZATION_NVP(pVec);

导致了这个错误。删掉这一行后，一切都正常了，结果和预期的一样.有人有写自己的序列化存档的经验吗？

这里解决了一个简单的问题https:/groups.google.comforum#！topicboost-listCMoDosGZUo8。但我没能通过前向声明来解决这个问题。

我解决了这个问题，把

#include <boost/archive/detail/archive_serializer_map.hpp>

由

#include <boost/archive/impl/archive_serializer_map.ipp>
