Re: [Boost-users] templating usage of state<>

(4) finally, I templated the state<> version, , which has problems.

[NOTE: I've referenced line # 3773 below, to sync with output]

struct NDIREV_17 {};

template< typename I > struct Start;

template< typename I > struct Inst : public sc::state_machine< Inst<I>, Start<I> > {};[ line# 3773 ]

template< typename I > struct Start : public sc::state< Start<I>, Inst<I> > { Start<I>(my_context ctx ) : my_base( ctx ) {} };

Did you try this way: template<typename I> struct Inst : public sc::state_machine<Inst<I>, mpl::list<Start<I> > >

// same 'main'

//************************************************************************ (5) ATTEMPTS TO FIX:

a) look @ code in state.hpp ( shown below ) and attempt to replace "my_context" & "my_base" with direct substitutions of "simple_state" and this->set_context.... no luck.

REQUEST FOR HELP: Could someone who has successfully templated both the machine<> and the state<> classes possibly give me a hint as to what I might be able to do to fix this bug?

Thank you for your time and effort;
