Thank you for your quick respond.
I'm sorry for the small errors in my code, below is a code that compiles,
but as I try to run ./statemachine I get the following error:

Starting Elevator
Entering Elevator Idle At Floor state
Exiting Elevator Idle At Floor state
statemachine: ../boost/boost/cast.hpp:97: Target
boost::polymorphic_downcast(Source*) [with Target = ElevatorSM*, Source =
boost::statechart::state_machine<ElevatorSM, ElevatorActive,
std::allocator<void>, boost::statechart::null_exception_translator>]:
Assertion `dynamic_cast<Target>(x) == x' failed.
Aborted

So it is unable to run the test123() from the elevator class.
