Hi
Fun time has started !
it looks like the SoapySDR use is not going to work as a git clone does
not load the soapy config cmake files , no manifest either
so
build gr-osmosdr from the link on the gqrx hardware (sdrplay) link
https://gqrx.dk/supported-hardware#sdrplay
which now points at
https://github.com/willcode/gr-osmosdr
So I git cloned and built
I found when trying to build gqrx-2.11.5 to errors stopped the
build,first it was not a git file and second gnuradio-runtime was missing
.libgunradio-runtime was installed
looking at the readme.md file with the source code I found
$ git clone
https://github.com/csete/gqrx.git gqrx.git
$ cd gqrx.git
$ mkdir build
$ cd build
$ qmake ..
$ make
So I did just that and gqrx built no errors, hence the use of 2.12.1-52
starting gqrx I've use in the config: other soapy=0 driver=sdrplay
Gqrx starts , but the input controls for the RSP1A( gain IF & RF ) are
not shown, and the waterfall is just white
When starting gqrx

no mention of sdrplay
I suspect gr-osmosdr doesn't have sdrplay support on the git branch the
link on the gqrx hardware page now points to.
I'm beginning to smell a rat, the sdrplay forum has been dumped , the
linux api is ancient and the soapysdr git files look old
Going back to the gqrx harware page
under sdrplay
"One can use it through the SoapySDR backend using device string
*soapy=0,driver=sdrplay* or using the recent gr-osmosdr updates by Jeff
Long <
https://github.com/willcode/gr-osmosdr> (recommended and included
in the .tar.xz binaries for Linux)"
the gr-osmosdr updates , are they separately available as a tgz file ???
I could do with some useful pointers, as others when they upgrade to any
of the distros using the ubuntu20.04LTS libs with a RSP1a are going to
have similar problems .
TIA
