Hey, I'm trying to start a thread from a Class but the only way I did it was using a pointer. The thing is that when I assign the thread to the pointer it wont start unless I use join(). I need it to star right away is created just like when I create a thread (boost::thread myThread(funcName);) I was trying to use thread_group to do this, but create_thread is not working. *Here's an example of what I was doing:* *(Here I used the pointer)* class Thread { public: Thread(){}; virtual ~Thread(){}; virtual void run() = 0; void start(){m_Thread = new boost::thread( &Thread::run, this ); }; //wont start unless I add m_Thread.join(); private: boost::thread* m_Thread; }; *and now... I am trying to use thread_group:* class Thread { public: Thread(){}; virtual ~Thread(){}; virtual void run() = 0; void start(){g_Thread.create_thread(&Thread::run); }; private: boost::thread_group g_Thread; }; *But I receive an error:* /usr/local/include/boost/thread/detail/thread.hpp: In member function 'void boost::detail::thread_data<F>::run() [with F = void (Thread::*)()]': main.cpp:61: instantiated from here /usr/local/include/boost/thread/detail/thread.hpp:56: error: must use '.*' or '->*' to call pointer-to-member function in '((boost::detail::thread_data<void (Thread::*)()>*)this)->boost::detail::thread_data<void (Thread::*)()>::f (...)' make[2]: *** [build/Debug/GNU-MacOSX/main.o] Error 1 Im using netBeans on Mac OS X 10.6.2 Anyone knows how should I create this? or how to use simple boost::thread and launch it without using join()?? Thanks!!! Dann
