Ctrlport-monitor: radio.get threw exception (math domain error)

GNU Radio
1

I get the following error when trying to the run gr-perf-monitorx
against a
flow graph that has an RTL_SDR radio as the source. I recompiled both
rtl_sdr and gr_osmosdr after enabling performance counters in gnuradio.

The odd thing is that it works fine when I do not have an RTL_SDR radio
attached. In that instance gr-osmosdr simply attaches a null source
instead. This seems to point to the RTL_SDR source. Has anyone
succesfully
used gr-perf-monitorx with a RTL_SDR source?

Thanks

PS - also just in case anyone else tries, ‘perf top’ doesn’t work in a
VM…

Luke,

This gut buried in my inbox. Any updates on your success with this? Are
you
running into this on a VM? It might be something related to that,
anyways.

Not a problem - It was under a VM, so that is probably what was causing
it.
I ran it at home on bare metal with a HackRF and didn’t have any issues.
