C++ 对体系结构x86_64使用未声明的标识符和未定义的符号

但是当我使用std:：runtime\u错误添加

时，错误为

#include <map>
#include <fstream>
#include <string>
#include <stdexcept>

using std::string;
using std::map;
using std::ifstream;

map<string, string> buildMap(ifstream &map_file)
{
  map<string, string> trans_map;
  string key;
  string value;
  while (map_file >> key && getline(map_file, value))
      if (value.size() > 1)
          trans_map[key] = value.substr(1);
      else
          throw runtime_error("no rule for " + key);
  return trans_map;

}

int main()
{
    return 0;
}

 cppMapTest.cpp:19:19: error: use of undeclared identifier 'runtime_error'
        throw runtime_error("no rule for " + key);
