I am using Boost 1.43 and last line in the following code causes this error: /usr/local/include/boost/property_tree/detail/ptree_implementation.hpp:471: error: ‘class boost::multi_index::detail::bidir_node_iterator

, boost::property_tree::basic_ptree, std::basic_string > > >, std::allocator, std::basic_string > > > > > > >’ has no member named ‘base’

Here is the code fragment. pt is the property tree. std::string key = "program.query"; std::size_t num = pt->count(key); std::cout << "Number = " << num << std::endl; typedef boost::property_tree::ptree::assoc_iterator assocIt; typedef std::pair< assocIt, assocIt > TRangeItPair; TRangeItPair er = pt->equal_range(key); The only fix I could see was here: http://lists.boost.org/boost-users/2010/02/55806.php But I cannot see how to apply it to the above code fragment. Any help is appreciated. Regards Andrew -- ___________________________________________ Andrew J. P.
