This is not a duplicate question, because the solutions presented are not working on my compiler. I am trying to compile and run the following example from this question.

#include <thread>
#include <iostream>

int main(int, char **){
    std::thread tt([](){ std::cout<<"Thread!"<<std::endl; });
    tt.join();
}

I have attempted to use the solutions presented in both that original question as well as the accepted answer to this duplicate. However, although I tried all the combinations listed, and in particular tried

g++  main.cpp -o main.out -pthread -std=c++11

When I run the resulting executable, I still get

terminate called after throwing an instance of 'std::system_error'
  what():  Enable multithreading to use std::thread: Operation not permitted
Aborted (core dumped)

Here is the output of g++ --version.

Is there a different ordering or set of commands I need to use for g++ 4.8.1?
