Re: [Boost-users] [Serialization] error C2027: use of undefinedtype 'boost::serialization::extended_type_info_null<T>'?

Note that the library is in two parts. libboost_serialization.. contains code used for all types of archives while libboost_wserialization contains code used only for wide character archives. So applications using wide character archives should link against BOTH libraries. Robert Ramey
