[Hackrf-dev] ImportError: /usr/lib/x86_64-linux-gnu/libgnuradio-osmosdr.so.0.1.5git: undefined symbol: _ZN3uhd6device4findERKNS_13device_addr_tE

[Dave New]

Dominic,

After a LOT of uninstalling/reinstalling, etc.  I finally found an old 
link/library lurking.  I deleted it, re-installed, and finally got 
things working again.  I have a presentation to make this afternoon, so 
I'm not touching anything at the moment.

Thanks for the assist,

73, Dave, N8SBE
