我读XML文件，并存储到的boost :: property_tree :: ptree中PT（对象）。
我试图使用该方法序列化此ptree中对象serialize()中定义的ptree_serialization.hpp
boost::property_tree::serialize(ar,pt,1);
当我在上面的代码中使用我得到错误的;
boost/serialization/collections_save_imp.hpp:64:9: error: no match for ‘operator<<’ in ‘ar << boost::serialization::make_nvp(const char*, T&) [with T = const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >]((* &((boost::iterator_facade<boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator, std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >, boost::bidirectional_traversal_tag, const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&, int>*)(& boost::operator++ [with I = boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator, V = std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >, TC = boost::bidirectional_traversal_tag, R = const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&, D = int, typename boost::detail::postfix_increment_result<I, V, R, TC>::type = boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator]((*(boost::iterator_facade<boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator, std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >, boost::bidirectional_traversal_tag, const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&, int>*)(& it)), 0)))->boost::iterator_facade<I, V, TC, R, D>::operator* [with Derived = boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> >::const_iterator, Value = std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >, CategoryOrTraversal = boost::bidirectional_traversal_tag, Reference = const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&, Difference = int, boost::iterator_facade<I, V, TC, R, D>::reference = const std::pair<const std::basic_string<char>, boost::property_tree::basic_ptree<std::basic_string<char>, std::basic_string<char> > >&]()))’
能否请你让我知道，如果我做错了什么。 能否请你让我知道，如果我们能够序列化的XML解析财产ptree中的对象。
