I have no idea how to do that. I've never had a problem with the last 18 or so releases.

Let me tell you that I had no problems building qt-dab on my Rpi 3 around 1 month ago. But I have not tested rtl_sdr as I am using an Airspy normally.

With the latest Raspbian also the spectrum can be used, too.

from qt-dab.

I set all RTL-SDR selections to reinstall using synaptic

This has allowed me to launch QT-DAB. Channels are showing, but the moment I click on anything, including "quit" everything seizes. It unseizes for a few seconds, allowing spectrum to lock and show dots, but then it loses lock and interface freezes.

Update:
I added:
SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2838", GROUP="adm", MODE="0666", SYMLINK+="rtl_sdr"
to etc/udev/ in a file called rtl2838.rules and rebooted. Can't harm to try. However program seizes still.

You always can download older versions. This is the benefit of github.com

Just go to the commits page and you see a <> button on the right.

Have created rules file in udev, rebooted etc, but still getting blocked.
Have deleted rule and installed rtlsdr dev package and got a bit further, however it crashes upon block selection

Further update: Have managed to get BBC block (12B) but receiver doesn't stay locked onto signal, just digital artifact noise from the soundcard after a few seconds. I keep reselecting channels and only get a lock for a few seconds.

Have reflashed SD Card since last attempt (latest raspian 7th september). Have installed RTL-SDR again. Still having sporadic crashing. Audio has stopped working in the last few minutes without changing anything. Muting then unmuting audio on the Desktop brings it back however the audio is choppy.

No discernible errors written in console. Am trying to work out how to get an older version, about a month ago was OK.

Raspian Stretch 7th September Release.

I have retracted to Commits on Sep 21, 2017, works pretty well. Although the BBC loses sync whenever it gets to the hour for some reason.

I will continue to try to get it working, I would suggest getting a Pi3 as this may become a problem for your software.

from qt-dab.

Yes, you may close the issue. Although I'd like to work out why the GCC compilers aren't up to scratch or allowing compilation of latest code. This isn't down to you though, as it's a Pi3 library issue.
