Hi,

I get the following error :

error C2664: 'void boost::function0<R,Allocator> ::assign_to(Functor)' : 
unable to convert parameter 1 from 'const CTaskManager' to 'CTaskManager'

when doing this :

class CTaskManager
{
    public:
        CTaskManager();
        ~CTaskManager();
        void operator()() {}
   
    private:
        boost::mutex m_mutex;
}

and

CTaskManager taskManager;
boost::thread_group mainThreadGroup;
mainThreadGroup.create_thread(taskManager);
mainThreadGroup.join_all();

The error dissapears when I remove the mutex from the definition of  
CTaskManager ... (?!!)

So what is the right way to use mutex and threads together? Do I have to 
declare the mutex outside of the
functor? Why?
