Hello, in my application I wrote the serialization like in the pimpl example. With boost 1.34.1 this has worked. But now I have a few strange linker errors. e.g Error 1413 error LNK2001: unresolved external symbol "protected: __thiscall boost::archive::detail::archive_pointer_oserializer<class boost::archive::detail::polymorphic_oarchive_route<class boost::archive::binary_oarchive_impl<class boost::archive::binary_oarchive,char,struct std::char_traits<char> > > main.obj and Error 1414 error LNK2001: unresolved external symbol "protected: __thiscall boost::archive::detail::archive_pointer_iserializer<class boost::archive::polymorphic_binary_iarchive>::~archive_pointer_iserializer<class boost::archive::polymorphic_binary_iarchive>(void)" (??1?$archive_pointer_iserializer@Vpolymorphic_binary_iarchive@archive@boost@@@detail@archive@boost@@$$FIAE@XZ) main.obj The problem has something to do with BOOST_CLASS_EXPORT(A) function. If I don't include it there is not the problem with the linker error. In the cpp file I have at the moment the instantion template void A::serialize(boost::archive::polymorphic_iarchive & ar,const unsigned int file_version); template void A::serialize(boost::archive::polymorphic_oarchive & ar,const unsigned int file_version); and template void A::serialize(boost::archive::binary_iarchive & ar,const unsigned int file_version); template void A::serialize(boost::archive::binary_oarchive & ar,const unsigned int file_version); What I have to do to solve that? Best regards Hansjörg
