Hi John,
looks like the the problem might (not sure) be that
something tries to access a different version of the python
libraries than you use now – so, seeing that simple_ra doesn't
come with any code that needs to be compiled itself, it does look
like there might be a remnant of your 14.04-time GNU Radio
installation *somewhere* on the system.
Soo, checking the usual suspects: did you also recompile
gr-osmosdr after you rebuilt GNU Radio and UHD?
Best regards,
Marcus

Hi,
While I usually regret it, I decided to update my Ubuntu system
from 14.04 LTS to 16.04 LTS and it seemed to go fine. I rebuilt
GNURadio and UHD and that seemed to go fine but when I run
Simple_ra with:
simple_ra --aperture 2.4 --ant RX2 --srate 10.0e6 --dbw 8.0e6
--freq 1420.4057e6 --gain 37.5 --dcg 1000 --lrate 30 --integ 30

When I fed the failure message to professor GOOGLE, I got talk of
snap and xevilteddy but the commands for 32-bit didn't seem to
work for my 64-bit i7 system.
Any idea(s) about how I can get rid of this message?
kind Regards,
John
