I keep on getting the error: c:\temp\boost\boost_1_33_0\boost/type_traits/is_abstract.hpp(81): error: incomplete type is not allowed BOOST_STATIC_ASSERT(sizeof(T) != 0); ^ detected during: instantiation of class "boost::detail::is_abstract_imp2<T> [with T=TxsOqSourceMaterialization]" at line 121 I checked that I have put the appropriate archive statement in class. How can I get rid of this compile error? ------------------------------------------------------------------------------ Yahoo! Personals Single? There's someone we'd like you to meet.
