[Boost-users] Problem with boost 1.36, vs2005 and serialization library -> linker problem

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> > > 
 >::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> > > 
 >(class boost::serialization::extended_type_info const &)" 
(??0?$archive_pointer_oserializer_at_V?$polymorphic_oarchive_route_at_V?$binary_oarchive_impl_at_Vbinary_oarchive_at_archive@boost@@DU?$char_traits_at_D@std@@@archive_at_boost@@@detail_at_archive@boost@@@detail_at_archive@boost@@$$FIAE_at_ABVextended_type_info_at_serialization@3@@Z) 
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_at_Vpolymorphic_binary_iarchive_at_archive@boost@@@detail_at_archive@boost@@$$FIAE_at_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
