Hi Marcus,
Thanks. That was very helpful. If there was an instruction to run the
setup_env.sh script I missed it. I was flying a bit blind there, because the
link to the PyBOMBS web page from the GNUradio TWiki---i.e.,
URL: http://gnuradio.org/pybombs from
URL: http://gnuradio.org/redmine/projects/gnuradio/wiki/InstallingGRFromSource
leads to a non-existent page.
When I ran the setup_env.sh script, things started to work. That's a good
thing! I am concerned, however, that I have a mixed installation. What is
my best move? "rm"-ing all of the PyBOMBS stuff or just leaving well enough
alone (I realize that this question may not have a "closed form" answer, but
advice would appreciated nonetheless).
Best regards,
Dan
