Segmentation fault ubuntu 16.04

[adada...@gmail.com]

Hi,

Ever since upgrading from Ubuntu 14.04 to 16.04, GQRX hasn't worked correctly. Initially after the upgrade the program would launch but I use the SDRPlay module which requires the soapy drivers to utilize. When I would try to install them, I would get notification of broken packages. My thought was to completely remove and reinstall. see below:

• Operating system

LSB Version:    core-9.20160110ubuntu0.2-amd64:core-9.20160110ubuntu0.2-noarch:printing-9.20160110ubuntu0.2-amd64:printing-9.20160110ubuntu0.2-noarch:security-9.20160110ubuntu0.2-amd64:security-9.20160110ubuntu0.2-noarch

• How did you install gqrx, gnuradio  and other related packages, and which versions?

Precisely as laid out on the website:

http://gqrx.dk/download/install-ubuntu

including the purge steps.

• What device(s) are you using (USRP, RTLSDR, Funcube Dongle, …)?

SDRPlay  RSP2

• What is the exact error you get / problem you are having?

Has anyone ran in to this issue or have any insight as to what might be happening here?

Thanks,

Hi Dave

If you want to go to something based on Ubuntu 18.04 , either ubuntu 18.04 or linux mint 19

I can give you some help, I use a RSP1

You should probably run "gqrx -r" to reset the configuration and see
whether the soapysdr backend in the new installation can talk to the
SDRPlay. Using gqrx with sdrplay is a horribly broken concept at the
moment because gqrx uses gr-osmosdr, which has a soapysdr backend,
which loads a plugin that links to a library distributed as
binary-only. It's nothing less than a miracle when it actually works.

Thanks Richard,

I'll keep that in mind when I feel brave enough or pushed to upgrade!

Hi Alex,

yeah, I realized that unfortunately after I had purchased my RSP1. I do feel like the issue is the gr-osmosdr package like you say.

grumble grumble...

Thanks for the reply.

Update:

With the help of some of Richard's posts, I think I'm a few steps closer to getting it to work. Using SoapySDRUtil, it appears I have an undefined symbol and a missing object file.
