Hello everyone, I am trying to make a cheap USB dongle working with
gnuradio and gnuradio-companion.
I just tried to use a source block and link to a waterfall sink.
This is the error that I got:

<<< Welcome to GNU Radio Companion 3.10.1.1 >>>

Block paths:

What does this mean? How can solve this problem?
The dongle is working fine with SDRSharp or rtl_fm.

Thank you
