[Discuss-gnuradio] Trunk check-in dependency file breakage

[Johnathan Corgan]

I have recently checked in the updates to the hierarchical flowgraph
code as outlined in a previous email.

One of the changes is that there are no longer any gr_runtime.* files as
this class has been removed from the code as part of an API change.

However, due to the somewhat broken way we handle SWIG dependencies, a
reference to gr_runtime.i remains in the machine generated dependency
files (gnuradio-core/src/lib/swig/*.d).

This will cause an *already compiled* local copy of the trunk to fail
compilation once it is updated with the latest repository revision.  It
will *not* affect any freshly checked out copies.

If you run into this issue, you can either:

1) Edit gnuradio-core/src/lib/swig/*.d and manually remove the line that
references gr_runtime.i in each one, -OR-

2) Delete gnuradio-core/src/lib/swig/*.d and then run ./config.status
from the top-level directory, -OR-

3) Check out a fresh copy of the trunk and rebuild (simple but overkill.)

Patches welcome from anyone who has a better way of automating tracking
of SWIG dependencies that doesn't create the above issue when a
dependent file is removed.
