g++ 4.8.1 C++ Threads, std::system_error - operation not permitted?

Question

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?

I see. Unfortunately the proposed workaround also doesn't work. I hope someone on SO knows a better workaround. — merlin2011

Double check that you aren't running a previously built version of your application. — Collin Dauphinee

I manually remove the executable before I rebuild just to be sure. — merlin2011

Use Clang. I don't use Gcc for c++11 & 14 related stuff. Because clang is just simply faster than Gcc to implement these new features. And compiling Clang now is just like a piece of case. — user534498
