Sorry for trivial question - it's my first time with UHD. It works now,
thanks.

Hi Ben,
good news - the cmake-built gnuradio does not crash. However, I am not
completely happy yet: when I try some WFM receive example, it always
reports "frequency out of range". I have WBX in side A and DBSRX in side B
of USRP1. uhd_usrp_probe recognizes this well:
You're confusing "--spec" and "-a":
Usage: usrp_wfm_rcv.py [options]
Options:
-h, --help show this help message and exit
-a ARGS, --args=ARGS UHD device address args [default=]
--spec=SPEC Subdevice of UHD device where appropriate
-A ANTENNA, --antenna=ANTENNA
select Rx Antenna where appropriate
-f FREQ, --freq=FREQ set frequency to FREQ
-g GAIN, --gain=GAIN set gain in dB (default is midpoint)
-V VOLUME, --volume=VOLUME
set volume (default is midpoint)
-O AUDIO_OUTPUT, --audio-output=AUDIO_OUTPUT
pcm device name. E.g., hw:0,0 or surround51 or
/dev/dsp
--freq-min=FREQ_MIN Set a minimum frequency [default=87900000.0]
--freq-max=FREQ_MAX Set a maximum frequency [default=108100000.0]
Try:
usrp_wfm_rcv.py -a "type=usrp1" -spec "A:0" -A RX2 --freq 92.5e6
Which will use the daughtercard in slot "A" with antenna "RX2" on a
"type=usrp1" device.
