Eclipse C++ Linux "to_string was not declared in this scope"

Question

#include "Person.h"
#include <string>

using namespace std;

string Person::toSimpleString(){

     return getFirstName() + " " + getLastName() + ", Age " + to_string(5);
}

All of my strings are working fine but I cannot get the to_string function to work at all. Eclipse keeps telling me it is out of scope. Wht

Is Eclipse giving you a codan warning, or are you getting a compile error? — Fred Larson, Feb 04 '14 at 20:23
You need to compile with C++11 support, in order to use std::to_string — Collin Dauphinee, Feb 04 '14 at 20:24
If you use MINGW it probably won´t work [see this GCC issue](http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59076). Take a look [here](http://stackoverflow.com/questions/7521617/c11-to-string-function-where) too. — wesley.mesquita, Feb 04 '14 at 20:33

Does #include <string> need to be #include <string.h>?

I think you might be missing the ".h"

No, [string and string.h](https://stackoverflow.com/questions/9257665/difference-between-string-and-string-h) are different. – Oct 07 '14 at 22:40
Beware of the subtle difference, in C++ `#include ` is including the string class from the standard library, and **not** the standard C string manipulation functions (that can be included with `` in C++, or with `` in both languages) – Ale Oct 07 '14 at 23:25
Ahh wow, I didn't know there was a difference. Thanks for the corrections. – ylemp Oct 08 '14 at 15:23
