gqrx is probably build with an outdated version of gnuradio. The package build date is older than its dependencies:
https://archlinuxarm.org/packages/aarch64/gqrx
https://archlinuxarm.org/packages/aarch ... io-osmosdr
On Manjaro ARM (aarch64) which takes the same packages, gqrx fails to start with the following error:
gqrx: error while loading shared libraries: libgnuradio-digital.so.3.8.2: cannot open shared object file: No such file or directory
Note that on ArchLinux (non-arm), gqrx has been rebuilt after gnuradio was updated.
