The gnuradio "next" branch builds fine for me but "make check" fails for gr-trellis.

This is due to some work (by Ben Raynwar) that makes gr-trellis dependent on gr-digital (???) In particular the constants related to trellis_metric_type.h cannot be accessed in python/grc as part of the trellis module, but as part of the digital module (this problem appears for instance if you run some of the pccc/sccc examples in gnuradio-examples/grc/trellis). This can be an easy fix (import digital in all the grc blocks requiring metric types, and make appropriate changes). However I wonder what is the point of making a self-contained module like gr-trellis dependent on another module (gr-digital) If the only reason is to to use the "constellation" object in the "metrics" blocks then these blocks should reside in the gr-digital module instead of the gr-trellis, so that the latter can still be self-contained. Ben, can you please explain what is your rational in doing these changes. thanks, Achilleas Achilleas, This was my doing. Ben had moved the metric types into gnuradio-core to work with his constellation work, so I moved them over with everything else into gr-digital. I then made gr-trellis depend on gr-digital because of this. Because gr-trellis is an implementation of digital modulation, it makes sense that it should depend on gr-digital. I made sure that gr-trellis would both build and pass 'make check,' so the QA code is obviously not testing all of the proper dependencies and cases in gr-trellis. We need to fix that to make sure the applications still run as we move stuff around. Depending on what gr-trellis requires out of gr-digital, we could possibly import digital into the trellis module inside of the __init__.py file. Tom
