Question

My programs looks like below

#include <iostream>
#include <thread>
#include <exception>

void hello()
{
    std::cout << "Hello world!!!!" << std::endl;
}

int main()
{
    std::cout << "In Main\n";
    std::thread t(hello);
    t.join();
    return 0;
}

When I compile it using the following command I get no errors

g++-4.7 -std=c++11 main.cpp

But when I run it I get the following error

In Main
terminate called after throwing an instance of 'std::system_error'
what():  Operation not permitted
Aborted (core dumped)

Could someone help me with where I am going wrong?

Answer 1

When I use C++11 threads with GCC, i use:

g++ -std=c++0x -pthread -g main.cpp

That works for me.
