Failure to build some components and running usrp examples


#1

The following components were skipped either because you asked not
to build them or they didn’t pass configuration checks:

gr-audio-jack
gr-audio-osx
gr-audio-portaudio
gr-audio-windows
gr-comedi
gr-video-sdl
ezdop
gr-ezdop

These components will not be built.

(all other critical components were built)

I tried running the usrp_wfm_rcv.py but i got

Using RX d’board A: Flex 2400 Rx MIMO B

gr_fir_ccf: using SSE
gr_fir_fff: using SSE

That error looks like you’ve got some application locking the sound
card. Music player, esound, something like that?

Shouldn’t be, but that does imply you won’t rx any radio…
