Question

I am trying to capsulate a thread as it is shown here:
http://antonym.org/2009/05/threading-with-boost—part-i-creating-threads.html

But somehow I can’t even compile my program.. This:

/**
 *
 */
void AcceptConnectionThread::start(int param)
{
  m_thread = boost::thread(&AcceptConnectionThread::AcceptConnectionThreadRun, this, 0);
}


/**
 *
 */
int AcceptConnectionThread::AcceptConnectionThreadRun()
{
  return 0;
}

just gives me this:

Description Resource    Path    Location    Type   required from `boost::_bi::bind_t<R, F, L>::result_type boost::_bi::bind_t<R, F, L>::operator()() [with R = void; F = int (*)(); L = boost::_bi::list2<boost::_bi::value<AcceptConnectionThread*>, boost::_bi::value<int> >; boost::_bi::bind_t<R, F, L>::result_type = void]’   ServerNetwork       line 20, external location: /usr/include/boost/bind/bind_template.hpp   C/C++ Problem
Description Resource    Path    Location    Type   required from ‘void boost::detail::thread_data<F>::run() [with F = boost::_bi::bind_t<void, int (*)(), boost::_bi::list2<boost::_bi::value<AcceptConnectionThread*>, boost::_bi::value<int> > >]’    ServerNetwork       line 62, external location: /usr/include/boost/thread/detail/thread.hpp C/C++ Problem
Description Resource    Path    Location    Type too many arguments to function ServerNetwork       line 313, external location: /usr/include/boost/bind/bind.hpp   C/C++ Problem

This is the template-constructor that is used:

template <class F,class A1,class A2>
thread(F f,A1 a1,A2 a2):
    thread_info(make_thread_info(boost::bind(boost::type<void>(),f,a1,a2)))
{
    start_thread();
}

I really do not have any idea what the problem is..

EDIT:

Anyway, it works with this.. but this way I can’t pass any parameter..

/**
 *
 */
void AcceptConnectionThread::start(int param)
{
  m_thread = boost::thread(&AcceptConnectionThread::AcceptConnectionThreadRun);
}

use boost::bind

    /**
     *
     */
    void AcceptConnectionThread::start(int param)
    {
      int para_to_pass = 0;
      m_thread = boost::thread( boost::bind(&AcceptConnectionThread::AcceptConnectionThreadRun, this, para_to_pass));
    }


    /**
     *
     */
    int AcceptConnectionThread::AcceptConnectionThreadRun(int para)
    {
      // use para
      return 0;
    }
