It wouldn't start.
Running it from the command line revealed the following error: gqrx: symbol lookup error: /usr/lib64/libgnuradio-osmosdr-0.1.5git.so.0.0.0: undefined symbol: hackrf_device_list
Google shows nothing posted about this error in the last year, and some of the comments I did find about it related to broken symlinks.
SO....I proceeded to remove ALL of the SDR, radio, hamlib, gnuradio, linrad, hackRF, and other numerous assorted and sundry files from this machine. This took a bit of searching, as removing the software with the YaST package manager still leaves some debris behind in hidden config files and libs.
Did a reboot, reinstalled only gqrx and it's requirements, and was greeted by the same error.
SO.....back to searching, or I guess I can build it all from source, which takes a while, and can be no guarantee of producing an error-free install.
Well, it seems this package provides functionality for a lot of things:
"OsmoSDR Gnuradio Source supports the OsmoSDR hardware, but it also offers a wrapper functionality for FunCube Dongle, Ettus UHD and rtl-sdr radios."
Now to find out why it's broken....
