Here is the program I run:

#include <string>
 
 int main()
 {
  std::to_string(0);
  return 0;
 }

After I run, it returns an error:

PS C:\Users\Anurag\SkyDrive\College\Programs> g++ -std=c++0x ttd.cpp
 ttd.cpp: In function 'int main()':
 ttd.cpp:11:2: error: 'to_string' is not a member of 'std'

Does anyone have any suggestions for the problem below: to_string is not a member of std in the cpp- How to correct it?

    The cause:

    You have got this error because std::to_string is not an exact patch of MinGW, it doesn’t work on MinGW. It can destroy the current programs by using the [v]swprintf’s Windows versions because it can use the quality signatures to replace them. Therefore, it will be able to cause the problems. Solution:

    You can make std::to_string work in harmony with MinGW by getting a patch. The MinGW-w64 project’s MinGW-w64 distros that use GCC 4.8.0 or later can solve this problem. Despite its name, the project offers both 32-bit and 64-bit toolchains. This problem is also fixed by the Nuwen MinGW distro distribution.

  2. #include <string>
#include <sstream>

namespace patch
{
 template < typename T > std::string to_string( const T& n )
 {
 std::ostringstream stm ;
 stm << n ;
 return stm.str() ;
 }
}

#include <iostream>

int main()
{
 std::cout << patch::to_string(1234) << '\n' << patch::to_string(1234.56) << '\n' ;
}

    #include <sstream> must be included
