I am trying to learn C++, and I cant seem to get threading to work.
#include <iostream>
#include <thread>
using namespace std;
void thing(){
cout << "1 is a thing" << endl;
int num;
cin >> num;
}
int main(){
cout << "is 1 a thing?" << endl;
thread neat1(thing);
return 0;
}
identifier "thread" is undefined
Im on C++14

this is what happends if I compile via cmd
>g++ first.cpp -std=c++11
first.cpp: In function 'int main()':
first.cpp:13:5: error: 'thread' was not declared in this scope
