I've tried to implement an own archive type for boost serialization following official boost example to write archives.
#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;
}
Compiling this example with
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
leads to the following linker error
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()':

collect2: error: ld returned 1 exit status
It seems that serializing a pointer in
oa << BOOST_SERIALIZATION_NVP(pVec);
leads to this error. After deletion of this line everything works fine and the result is as expected. Does anybody have experience in writting own serialization archives?
A simimal Problem was solved here https://groups.google.com/forum/#!topic/boost-list/CMoDosGZUo8 but I wasn't able to solve this by forward declarations.
