Hi all:

 I am new to this group and I am GNU radios to listen to a band of
frequencies and see the spectrum by computing the FFT. The following

./ -R B -f 1e6 >> data_fft_1_2.dat

results in the following error.. Should I have some display settings
to avoid this? And why do I get a segmentation fault?

Traceback (most recent call last):
  File "./", line 251, in ?
    main ()
  File "./", line 247, in main
    app = stdgui.stdapp(app_flow_graph, "USRP FFT", nstatus=1)

SystemError: wxEntryStart failed, unable to initialize wxWidgets!  (Is
DISPLAY set properly?)
