Try this patch to boost/iterator/iterator_facade.hpp; does it fix the problem for you?
Yes. Well... It fixed THAT problem. After I took it a step further and tried to use the iterator like this: *iter = make_tuple(i, i*2.0); I then get this error: boost/tuple/detail/tuple_basic.hpp:377: error: no match for 'operator=' in '((boost::tuples::cons<void, boost::tuples::cons<void, boost::tuples::null_type> >*)this)->boost::tuples::cons<void, boost::tuples::cons<void, boost::tuples::null_type> >::head = u->boost::tuples::cons<int, boost::tuples::cons<double, boost::tuples::null_type> >::head' After looking into it further, it seems that std::back_insert_iterator inherits from std::iterator<std::output_iterator_tag, void, void, void, void>. Since it obviously has no interest in populating the right type information, would it make sense add partial specializations to boost/detail/iterator.hpp to grab the appropriate types from the container? e.g. template <class CONTAINER> struct iterator_traits<std::back_insert_iterator<CONTAINER> > { typedef typename CONTAINER::value_type value_type; typedef typename CONTAINER::reference reference; typedef typename CONTAINER::pointer pointer; typedef typename CONTAINER::difference_type difference_type; typedef std::output_iterator_tag iterator_category; }; I'll try this out and see if it works, but what is this the right way to go about it? I'm fairly new to C++ and boost development, so I'm looking to learn the correct ways. Thanks, Kris
