I have cloned and installed gr-inspector using the instructions on the webpage. One change (addition) necessary to get gr-inspector to install on my system (Ubuntu 17.10) was to run ln -s /usr/lib/libqwt-qt4.so.5 /usr/lib/libqwt-qt4.so ; otherwise cmake failed, unable to find libqwt-qt4.so.
I have started gnuradio companion and loaded an example from gr-inspector (live_signal_detection.grc). I adjust the sample rate, since I am using an RTL-SDR (adjust to 2.4e6). The graph comes up, and I press 'play' (execute the flow graph). I get this error: Found Rafael Micro R820T tuner [R82XX] PLL not locked! [R82XX] PLL not locked! Traceback (most recent call last): File "/home/rs/devel/gr-inspector/examples/live_signal_detection.py", line 142, in <module> main() File "/home/rs/devel/gr-inspector/examples/live_signal_detection.py", line 130, in main tb = top_block_cls() File "/home/rs/devel/gr-inspector/examples/live_signal_detection.py", line 85, in __init__ self.inspector_signal_detector_cvf_0 = inspector.signal_detector_cvf(samp_rate, 4096, firdes.WIN_BLACKMAN_hARRIS, AttributeError: 'module' object has no attribute 'signal_detector_cvf' GNUradio (3.7.10) executes other graphs fine (that is, non-gr-inspector graphs). Why am I getting this error with gr-inspector? Thank you
