gcc 4.7.2 和 boost 1.49 中的 boost::property_tree::read_json - 编译时错误答案

【问题标题】：boost::property_tree::read_json in gcc 4.7.2 and boost 1.49 - compile-time errorsgcc 4.7.2 和 boost 1.49 中的 boost::property_tree::read_json - 编译时错误
【发布时间】：2025-11-30 03:35:02
【问题描述】：

我有以下代码：

#include <boost/property_tree/json_parser.hpp>
#include <boost/property_tree/ptree.hpp>

#include <sstream>
#include <string>

int main()
{
  std::string input("{\"foo\":\"bar\"}");

  boost::property_tree::ptree pt;
  std::stringstream stream;
  stream << input;

  boost::property_tree::read_json(stream, pt);
}

在带有 boost 1.54 的 MSVC-11.0 中，这段代码编译得很好，但在带有 boost 1.49 的 gcc 4.7.2 中，这段代码给了我以下错误：

我做错了什么？我该如何解决？

【问题讨论】：

您的错误消息已损坏，无法理解。它们的关键部分从底部开始，位于“/usr/include/boost/property_tree/detail/json_parser_read.hpp:105:17: error: no matching function”，但它列出的内容没有任何意义。
@Sebastian Redl 是的，我已经看到了，但根据文档，这种功能存在于 boost 1.49 - boost.org/doc/libs/1_49_0/boost/property_tree/json_parser.hpp
错误是指库的内部。我正试图找出发生了什么，但因为消息是乱码而无法查明。
@Sebastian Redl 不幸的是，我没有任何其他信息
我刚刚注意到，当我使用 -std=c++98 而不是 -std=c++11 时，我可以编译这段代码

标签： c++ boost

【解决方案1】：

正如 OP 问题的 cmets 中所述，当使用 boost::property_tree::read_json 时，boost 1.49 不能与 c++11 一起编译。这是一个known bug，可以通过使用更新版本的 boost 或应用以下补丁来解决：

描述了here。
