Here it is:
#include <boost/statechart/state_machine.hpp>
#include <boost/statechart/simple_state.hpp>
#include <boost/statechart/event.hpp>
#include <boost/statechart/in_state_reaction.hpp>
namespace sc = boost::statechart;
struct Event1 : sc::event<Event1>
{};
template<class Derived, class Outer>
struct ActiveBase : sc::simple_state<Derived, Outer>
{
void f(const Event1 &)
{}
};
struct Active;
struct FSM : sc::state_machine<FSM, Active>
{
};
struct Active : ActiveBase<Active, FSM>
{
typedef sc::in_state_reaction<Event1, ActiveBase, &ActiveBase::f> reactions;
};
int main()
{
FSM fsm;
fsm.initiate();
}
