[Boost-users] boost::bind with template

Hi, I would like to create a thread group for my "worker objects" like: std::vector< worker > l_worker; boost::thread_group l_threads; for(std::size_t i=0; i < p_threads; ++i) { l_worker.push_back( worker(p_iteration, p_stepsize, m_derivation, m_optimize, m_static, p_batch) ); l_threads.create_thread( boost::bind( &worker::optimize ), l_worker[i] ); (*) } I get a compiler error at (*) on boost/bind/bind.hpp: In instantiation of 'boost::_bi::result_traits::*)()>': error: 'void (worker::*)()' is not a class, struct, or union type boost/bind/bind_template.hpp:15: instantiated from 'boost::_bi::bind_t::*)(), boost::_bi::list0>' The variables T is a typename and D is std::size_t > 0 How can I bind my template object () to the create_thread methode? Thanks Phil
