Here's part of check.hpp where the problem is:

template<class T>
inline void check_const_loading(){
    typedef
        BOOST_DEDUCED_TYPENAME mpl::or_<
            BOOST_DEDUCED_TYPENAME boost::serialization::is_wrapper< T >,
            BOOST_DEDUCED_TYPENAME mpl::not_<
                BOOST_DEDUCED_TYPENAME boost::is_const< T >
            >
        >::type typex;
    // cannot load data into a "const" object unless it's a
    // wrapper around some other non-const object.
    BOOST_STATIC_ASSERT(typex::value);         // <-------------
Compiler points here for the error
}

} // detail
} // archive
} // boost

I must also say that I got all the code working in small test project
but this error comes up in my big project.
