[Boost-users] [serialization] linker errors using polymorphic archives

Hi,

I'm trying to use the polymorphic interfaces so I can separate
components in a serialization library, however I'm having problems
resolving the following linker errors using vc71:

boost error LNK2019: unresolved external symbol "public: void __thiscall
boost::archive::text_iarchive_impl<class
boost::archive::text_iarchive>::load(class std::basic_string<unsigned
short,struct std::char_traits<unsigned short>,class
std::allocator<unsigned short> > &)"
(?load@?$text_iarchive_impl_at_Vtext_iarchive_at_archive@boost@@@archive_at_boost
@@QAEXAAV?$basic_string_at_GU?$char_traits_at_G@std@@V?$allocator_at_G@2@@std@@@Z
) referenced in function "private: virtual void __thiscall
boost::archive::detail::polymorphic_iarchive_impl<class
boost::archive::text_iarchive_impl<class boost::archive::text_iarchive>
>::load(class std::basic_string<unsigned short,struct
std::char_traits<unsigned short>,class std::allocator<unsigned short> >
&)"
(?load@?$polymorphic_iarchive_impl_at_V?$text_iarchive_impl_at_Vtext_iarchive@
archive_at_boost@@@archive_at_boost@@@detail_at_archive@boost@@EAEXAAV?$basic_str
ing_at_GU?$char_traits_at_G@std@@V?$allocator_at_G@2@@std@@@Z)

and similar for the save interface.

I am getting a similar problem using the test example - verbatim - from
the doc page
http://www.boost.org/libs/serialization/doc/archive_reference.html#polym
orphic, even after explicitly declaring

template void
boost::archive::text_oarchive_impl<boost::archive::text_oarchive>::save(
std::basic_string<unsigned short,struct std::char_traits<unsigned
short>,class std::allocator<unsigned short> > const &);

Does anyone have any recommendations for this?

Thanks in advance,
Sebastian
