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?
