So I wrote a program to test threads on 64 bit kubuntu linux, version 13.04. Actually I robbed the code from someone else who was writing a test program.


    #include &lt;cstdlib&gt;
    #include &lt;iostream&gt;
    #include &lt;thread&gt;
    
    void task1(const std::string msg)
    {
        std::cout &lt;&lt; &quot;task1 says: &quot; &lt;&lt; msg &lt;&lt; std::endl;
    }
    
    int main(int argc, char **argv)
    {
        std::thread t1(task1, &quot;Hello&quot;);
        t1.join();

        return EXIT_SUCCESS;
    }


I compiled using:

    g++ -pthread -std=c++11 -c main.cpp
    g++ main.o -o main.out

Then ran:

    ./main.out

As an aside, when I &#39;ls -l&#39;, main.out shows up in in green text like all executables, but also has an asterisk at the end of its name. Why is this?

Back to the problem in hand: When I ran main.out, an error appeared, which said:

    terminate called after throwing an instance of &#39;std::system_error&#39;
      what():  Operation not permitted
    Aborted (core dumped)

Anyone any ideas on how to fix this?
