Re: [Boost-users] [Statechart] Passing reference to create_processor()

It appears that the create_processor implementation instantiates code that attempts to copy the argument.

It does, and this is why you must pass boost::ref wrapper instead of the reference itself.

processor1 = scheduler.create_processor (boost::ref(value));

Here you instruct the compiler to convert the parameter into Object &, and therefore boost::ref has no effect, as the conversion takes place "before" the create_processor call. Just omit the "Object &" template parameter and let the compiler deduce it and the code should compile. HTH Juraj Ivančić
