Thanks!
But I said that the thread wont start because in other class I defined, that
inherits from this "Thread" class.
I implemented the abstract run() method so it just prints a line to the
output:

class Trash : public Thread {
    std::string garbage;
public :
    Trash(std::string newString){garbage = newString;};
    void run(){ std::cout << "RUNNING" << std::endl;};
}

int main(int argc, char** argv) {
    Trash myTrash("hello");
    myTrash.start();
}

and whenever I run the project (using boost::thread or using
boost::thread_group with the correction you provided) it wont show the
output... "RUNNING".
BUT, if I add m_Thread.join(); it shows that output.
Any idea why?

Thanks!!
