[FIXED] c++ unable to resolve identifier to_string

Issue

Good day

I have searched high and low, yet no solution.

IDE: NetBeans IDE 8.2 MinGW: Using the "latest" MinGW compiler.

Original Issue:

I would like to convert an int to string.

Using href="https://stackoverflow.com/questions/5590381/easiest-way-to-convert-int-to-string-in-c">this method, I attempted to convert to string, however

this proposed method std::to_string() results in the error when used(with the to_string as the error)

unable to resolve identifier to_string

Project dependancies:

#include <string>
#include <iostream>

Searching for a solution to this issue, 2 promonent solutions appeared here and here

Setting the C and C++ compiler versions should apparenlty solve this issue.

It did not, any suggestions?

Minimal Code:

#include <string>

struct User_VPN_Info{
    std::string name, expire;
    int DaysLeft;

    User_VPN_Info(){}

    User_VPN_Info(std::string _name, std::string _expire, int _DaysLeft){
        name = _name;
        expire = _expire;
        DaysLeft = _DaysLeft;
    }

    std::string getString(){
        return(name + " + " + expire + " + " + std::to_string(DaysLeft) + " ; ");                                                    
    }                                             //^_______^ problem here
};

Solution

It is know issue with MinGW

gcc  -std=gnu++14 -Wall -Wextra  main.cpp
main.cpp: In function 'int main()':
main.cpp:24:26: error: 'to_string' was not declared in this scope
     cout<<to_string(a)<<endl;

gcc  --version

gcc.exe (GCC) 5.3.0

Instant of 'standard" MinGw you should use MinGW-w64 - for 32 and 64 bit Windows

/mingw-w64/i686-6.2.0-posix-dwarf-rt_v5-rev1/mingw32/bin
./g++   -std=c++14   main.cpp

compile without errors

If you want change toolchain in Netbeans you have to add new Tool Collection in project properties.
