Я пытаюсь выполнить синтаксический анализ JSON с помощью синтаксического анализатора property_tree Boost и кода C ++ 11 (моя система - Debian Wheezy с gcc 4.7.2 и Boost 1.49). Я попробовал следующий код на основеСериализация и десериализация JSON с бустом:

#include <map>
#include <sstream>
#include <boost/property_tree/ptree.hpp>
#include <boost/property_tree/json_parser.hpp>
using boost::property_tree::ptree; using boost::property_tree::read_json; using    boost::property_tree::write_json;

void example() {
  // Write json.
  ptree pt;
  pt.put ("foo", "bar");
  std::ostringstream buf; 
  write_json (buf, pt, false);
  std::string json = buf.str(); // {"foo":"bar"}

  // Read json.
  ptree pt2;
  std::istringstream is (json);
  read_json (is, pt2);
  std::string foo = pt2.get<std::string> ("foo");
}

Если я скомпилирую это сg++ -std=c++03 -c' everything is fine. However, I also want to use C++11 features (which the code in the linked thread actually does!). But withg ++ -std = c ++ 11 -c 'Я получаю ошибки компиляции:

Как я могу использовать Boost's read_json с C ++ 11? Нужна ли мне более новая версия Boost для этого (т.е. установить вручную из исходного кода вместо использования пакета Wheezy)? Что-то не так в моем коде? Или это просто невозможно?
