Hi Marcus,
An update - i reinstalled python-wxgtk2.8 and that
dependency was satisfied when I re-ran Marcus' build_gnuradio script.
When I run the same command as before, I now get:

So while I still have the malloc assert, I seem to have gained an
issue with logger_tp.
Not sure what else I should try?
Kind Regards,

Hi John,
you could find the exact libosmosdr*.so that is used at runtime. Of
course, searching your filesystem for any libosmosdr* would be
clever, but it might be that you have multiple prefixes or so, so we
might as well make sure that at the time python actually starts
loading libraries, nothing looks in the wrong places:
I'm sure we could come up with cooler ways of doing that, but for
now, why not simply run
strace -e trace=open -o opened_files.txt python2 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 --devid
uhd='a',type=usrp2,addr=192.168.10.2,lo_offset=7.34e6,subdev=A:0
--longitude 172.570925 --latitude -43.519023
and then something like
grep osmosdr opened_files.txt
Then, simply check the file modification date of that file :)
Best regards,
Marcus

Thanks Marcus,
I used the other Marcus' build_gnuradio
script and I believe that it rebuilt gr-osmosdr. How would I check?
I built 3.7.11.1 on July 7th on 14.04 LTS
and today, I rebuilt again on 16.04.
Kind Regards,
John

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

GNURadio and UHD and that seemed to go fine but when I run

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

Did you install pyephem?
It may be that simple_ra_utils is failing import because it imports "ephem".
