Note : C ++ does not support default - int syntax error : missing ',' before '&' ' void A :: B :: Y :: fun ( X & ) ' : overloaded member function not found in ' A :: B :: Y ' It seems to overwrite the root namespace scoping (in this case, A , making A::X not found). This is fixable by explicitly writing all namespaces like such:
