I'm using code::blocks IDE. I want to use stoi in my code but always

I take this error :

'stoi' was not declared in this scope I'm using gnu gcc compiler 4.8.1 and i'm using c++11 and I have 64bit computer.

I've checked on the internet and I've made the changes specified on this page: http://tehsausage.com/mingw-to-string

I don't wonna use atoi! but i can't use stoi yet!

#include <iostream>
#include <stdlib.h> 
#include <string> 

using namespace std; 

int main()
{ 
   int temp; 
   string test = "123hello"; 
   temp = stoi(test); 
   cout << temp; 
   return 0; 
}

Maybe read [a good reference](http://en.cppreference.com/w/cpp/string/basic_string/stol). – juanchopanza Jul 25 '15 at 08:00
Did you `#include ` ? – Axel Guilmin Jul 25 '15 at 08:02
yes of course! I've included string and used namespace std – Ahmadreza Jul 25 '15 at 08:10
@juanchopanza I've did it right! – Ahmadreza Jul 25 '15 at 08:13
@Ahmadreza That is very unlikely, otherwise it would have worked. In any case, you have shown no evidence that you "did it right". – juanchopanza Jul 25 '15 at 08:17
can you paste some code... – Nick Jul 25 '15 at 08:18
I just initialized a string and used stoi and put the returned value in a variable! – Ahmadreza Jul 25 '15 at 08:19
@Nick : #include #include #include using namespace std; int main(){ int temp; string test = "123hello"; temp = stoi(test); cout << temp; return 0; } – Ahmadreza Jul 25 '15 at 08:20
are you sure #include is same as #include? also try std::stoi() instead of stoi() – Nick Jul 25 '15 at 08:30
I've tested it ! the same error ! :(( – Ahmadreza Jul 25 '15 at 08:33
You code works fine on Ubuntu with g++ 4.8.4 so it must be a minGW/g++ 4.8.1 issue. – Scooter Jul 25 '15 at 08:40
does the answer here help: [how can i add c++11 support to code::blocks compiler?](http://stackoverflow.com/a/24398366/539810) – Jul 25 '15 at 08:42
@ChronoKitsune I've done this works! – Ahmadreza Jul 25 '15 at 09:10
