I fixed the typedefs which allowed the test program to compile. Alas, I prudently used a typedef in my own application program when changing from std::map to boost::ptr_map. That typedef is correct. My minimal test example is not a true representation of my application program's problem. In the latter case when constructing the combining iterators, I'm getting: boost::detail::error_not_related_by_convertibility<T1,T2>' : base class undefined and 'type' : is not a member of 'boost::detail::minimum_category_impl<false,false>::apply<T1,T2>
I'm going back in another attempt to decipher the error messages and perhaps construct a small example program which demonstrates the problem.
There are some minor differences between std::map<K,T> and boost::ptr_map<K,T> and if this the types that gives you errors, it might be due to these differences. For example, boost::ptr_map<K,T>:::value_type is not a std::pair<const K,T>. There are also some difference in the way constness is handled, which might also be the source of your problem. Anyway, I would like to know more. best regards -Thorsten
