I was on 3.7.2, I believe. I used the build-gnuradio script to update to
3.7.4. My problem persists. However, odd things happen. I doubt it is
relevant to my actual problem, but here it goes:
5: ======================================================================
5: FAIL: test_001_t (__main__.qa_burst_to_power)
5: ----------------------------------------------------------------------
5: Traceback (most recent call last):
5: File
"/home/mehow/projects/gr-gsm_measure/python/qa_burst_to_power.py", line
124, in test_001_t
5: msg_pow.message_ports_in(), 0)), 'bursts')
5: AssertionError: 'system' != 'bursts'
5:
5: ----------------------------------------------------------------------
5: Ran 1 test in 0.005s
I don't have a port called 'system'. This happened only once and made me
tweak with the assertion statements. Now, when I check the message ports
against their actual names ('bursts' and 'power'), the assertion is passed,
but when I change the name to check against in the QA code I get (for both
of my ports):
5: AssertionError: 'system' != 'whatever_name_I_put_there'
Other than this oddity, I get exactly the same thing as at the beginning.
Could this happen because I have some leftovers of the previous version of
gnuradio after using the script?
