How to get gqrx working in Bionic64?

[Mercedes350se]

Still trying to ger the sdr dongle doing what I would like it to do - in the near term get gqrx working.

I should state that I am now using a frugal install of Bionic 64 bit (isn't puppy a beautiful animal?)

When I try to start gqrx I get:

Code: Select all

root#gqrx
linux; GNU C++ version 7.3.0; Boost_106501; UHD_003.010.003.000-0-unknown

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'
Controlport disabled
"Pulseaudio error: Connection refused"

and a pop up window stating "Audio Error"
Pulseaudio error: Connection refused
(and a button) Abort

Hi. There is no default Pulseaudio in Bionic. We need to find out if gqrx works with alsa. I am going to use gqrx in the future(in Fossapup - Pulseaudio support is promised there), but I am postponing the hardware purchase.
I want either HackRF or PortaPack+HackRF.

Edited. Apparently, you need to compile a version of gqrx with ALSA support.
To select audio backend add -DLINUX_AUDIO_BACKEND=Portaudio or -DLINUX_AUDIO_BACKEND=Gr-audio to the cmake command line.
I'll do it, but for Fossapup and not now.
