corrupted double-linked list

[Rolf T]

I have trouble with GQRX to run. When i type gqrx or click on the icon,
The computer is working for a while, but nothing happens. 

So out of 100 try its fail 99 times. 

Once it has started. Then it complained that the config file was corrupted. 

Also tested with gqrx -r

I have tried both RTL dongel and Funcube with the same negative results. 

The installation of the OS made with the latest version. Both with IMG files and NOOBS.
It is RPI is 3+

This is what the text in the terminal window looks like.

also receiving this error on my pi3 with raspbian 18.04 pixel and my limesdr-mini

installed limesuity and all of soapysdr and they tested the device fine

installed gqrx from repo and i get this error

Same problem here:  Using RTL with Rpi 3 plus latest GQRX version  and get the following error ;

Thanks

Perhaps the problem is in osmocom since I get this also:

pi@raspberrypi:~ $ osmocom_fft

Please try the binary package from the website.

That is where I got the package from.

[Alexander Fasching]

I don't think you did.
The archive from the website includes a more recent version of
gr-osmosdr. The output you posted shows gr-osmosdr 0.1.4, which is
exactly the version provided by the Debian/Ubuntu/Raspbian repositories.

If you download the package from the website, then you have to run Gqrx
with ./gqrx from the extracted archive.

Re-installed and works fine now - thanks.

https://www.reddit.com/r/RTLSDR/comments/7xvkm1/gqrx_doesnt_work_from_raspbian_repos/

I found this in the above link:

"

i found this by googling the "double linked list" error

Update:

I looked into this today, and it turned out to be the classical error: I had 2 versions of the gnu radio packages installed on my system and had built the gr-osmosdr against the wrong one. I have now removed the precompiled gnuradio, rebuilt gr-osmosdr and the crash is gone.

I found this with valgrind, because valgrind provided better stack traces than the glibc. "

Yes, the one at http://gqrx.dk/download/gqrx-sdr-for-the-raspberry-pi seems to be the only one that works on a Pi (3B here).  I just tried the deb version again because I was wondering if there's one that supports a bias tee and the direct tuning hack for HF.  The Pi version might not keep up with mainstream gqrx.
