Hi Everyone,
I was wondering if someone could help point out a possible solution to a
problem I have. I have written a component for Nox, which stores flows
to configure the switches and makes decisions on which flows to
implement. The problem I am struggling to get around is that the a user
or admin must be able to add new flows to the configuration table in the
component.
My thought was to write a second program which the user used as an
interface to configure the component and I would do this by passing a
reference of the component to the second program when the component is
created. However, I seem to be stuggling to get my second program to
compile when I add the component header to it. I'm pretty confident this
is a Makefile issue, because I have little experience with that stuff. I
will post the errors I get and the Makefile code for comments, but I was
also wondering if anyone know of a better way to do this? I was thinking
of having my second program inherit from Class Component so I could use
the resolve() function to get a handle on it, but being unfamiliar with
Nox I was not sure whether launching a seperate console UI when
launching Nox was a good idea.
Hope this makes sense! :-s Here is the Makefile stuff:
