Well, the good thing about installing anything that you've compiled manually into /usr/local/ is that you immediately know where your stuff with outdated linking is. Best regards, Marcus On 17.07.2017 19:26, John Shields wrote: > Thank Marcuses, > > I will work along

Thank Marcuses, I will work along the lines recommended by Marcus M and let you know. While I hate to think of it, I might need to do a clean install of 16.04 LTS and start my world over - which is sub-optimal.

Hi Marcus, Found the issue with command line you gave, namely simple_ra is not the python file so I changed the line to simple_ra_receiver and changed some of the command parameters as and got it to run: john@i7ubuntu:/usr/local/lib$ ls libgnuradio-osmosdr*.* -l -a lrwxrwxrwx

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,

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

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

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
