Not really.  If you want help you need to provide more details,
including cut/paste of the command you invoked, the exact error message
you received, and ideally a simple example makefile that shows the
behavior.

Offhand I'd say that some target in your makefile lists that include
file as a prerequisite, and so make is trying to build it and failing
because it doesn't exist and there's no rule to create it.

The -include thing just keeps make from complaining that the file
doesn't exist when it's being included: if you specifically list it as a
prerequisite then make will want to build it, if things that depend on
it are getting rebuilt.
