【问题描述】：
我正在读取 xml 文件并将其存储到 boost::property_tree::ptree pt(object) 中。
我正在尝试使用 ptree_serialization.hpp 中定义的方法 serialize() 序列化这个 ptree 对象
boost::property_tree::serialize(ar,pt,1);
当我使用上面的代码时，我得到的错误是；
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> > >&]()))’
如果我做错了什么，请告诉我。请告诉我我们是否可以序列化 xml 解析的属性 ptree 对象。
【问题讨论】：
-
你能告诉我们你是如何定义
ar和pt的吗？ -
ar 可以是 iarchive 或 oarchive 对象。 pt 被声明为 boost::property_tree::ptree pt;
-
我不是这方面的专家。
boost::property_tree::ptree pt(object)似乎缺少模板：<class Key, class Data, class KeyCompare>。我认为serialize根据其源代码需要basic_ptree类型作为第二个参数：boost.org/doc/libs/1_42_0/boost/property_tree/…，另见：codereview.stackexchange.com/questions/1818。看看他们是否有帮助
