Atomic types: terminate called after throwing an instance of "std::system_error"

Question

I am following this tutorial. I can compile the example by command line:

g++ -std=gnu++0x AtomicCounter.cpp -o AtomicCounter -lpthread

It works fine but when I run

./AtomicCounter

It gives the error:

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

I posted the code of AtomicCounter.cpp

#include <thread>
#include <atomic>
#include <iostream>
#include <vector>

struct AtomicCounter {
    std::atomic<int> value;

    AtomicCounter() : value(0) {}

    void increment(){
        ++value;
    }

    void decrement(){
        --value;
    }

    int get(){
        return value.load();
    }
};

int main(){
    AtomicCounter counter;

    std::vector<std::thread> threads;
    for(int i = 0; i < 10; ++i){
        threads.push_back(std::thread([&counter](){
            for(int i = 0; i < 500; ++i){
                counter.increment();
            }
        }));
    }

    for(auto& thread : threads){
        thread.join();
    }

    std::cout << counter.get() << std::endl;

    return 0;
}

EDIT:

Thank @Kerrek SB, it works when I changed to pthread instead of lpthread.

But I don't understand why. Can someone explain for me?

For more informations, I ran strace ./AtomicCounter

    access("/etc/ld.so.nohwcap", F_OK)      = -1 ENOENT (No such file or directory)
open("/lib/i386-linux-gnu/libpthread.so.0", O_RDONLY|O_CLOEXEC) = 3
read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\320]\0\0004\0\0\0"..., 512) = 512

close(3)     

                       = 0
