How did you install UHD and GNU Radio? When you say that the USRP is not
receiving the waveform, do you see just noise or does the application not
even start? What file was missing, there should definitely not be anything
missing from those versions.
I recommend ensuring that uhd_usrp_probe runs correctly and shows the X310
and TwinRX, then try using uhd_fft which comes with GNU Radio to see a
spectrum plot. If you are seeing only noise my guess is that you need to
increase the receive gain. The TwinRX has a very large gain range. Starting
around index 70 is usually good.
uhd_fft --freq 2e9 --gain 70
