You don't have to use bind here.

func( print ) ;

would work.

    bind ( &func<???>, bind(&print) ) ; //don't know how to write it
...
}
Note that this expression will not call anything, it will generate a functor
and drop it. I guess what you are trying to do is this

bind( func<void()>, print) ();  // note the function call operator at the
end.

or maybe this:

bind( func<void()>, _1) (print);
