Currently I don't understand why the following code dosn't compile (with VC 8.0). I simply try to bind the post_event() method from the state_machine to a function object. To illustrate the problem I've added the following code to the Camera.hpp file of the Camera example from the Statechart library: #include #include <snip> struct Camera : sc::state_machine< Camera, NotShooting > { // @test start typedef boost::function< void( const event_base_type& ) >process_event_fun; typedef boost::function< void( const event_base_type& ) > post_event_fun; process_event_fun process_event_fun_; post_event_fun post_event_fun_; Camera() { process_event_fun_ = boost::bind( &Camera::process_event, boost::ref( *this ), _1 ); // the following line doesn't compile with VC 8.0 // post_event_fun_ = boost::bind( &Camera::post_event, boost::ref( *this ), _1 ); } // @test end bool IsMemoryAvailable() const { return true; } bool IsBatteryLow() const { return false; } }; After uncommenting the marked line the compiler produce more than 200 error messages: A function template has too few arguments. But the line above compiles very well and the process_event() method has the same signature. The post_event() method is polymorphic. But this shouldn't be a problem. Should it?
