自定义存档的增强序列化中出现链接器错误

Question

我试图按照官方的boost示例来实现自己的存档类型，以进行boost序列化。

#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 datan";
}
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;
}

使用编译此示例

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 

似乎在中序列化指针

oa << BOOST_SERIALIZATION_NVP(pVec);

导致此错误。删除这一行后，一切都很好，结果如预期。有人有写自己的连载档案的经验吗？

这里解决了一个类似的问题https://groups.google.com/forum/#！主题/提升列表/CMoDosGZUo8但我无法通过正向声明来解决这个问题。

我通过更换解决了这个问题

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

通过

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