[Hackrf-dev] SDR with hackRF Lesson 1 issue with newer gnuradio-companion

[Richard Smith]

I went through lesson one last night.

If you build gr via pyBOMBS the by default the WX fft control does not 
work any more.

You get:

Error 0:
Block - wxgui_fftsink2_0 - WX GUI FFT Sink(wxgui_fftsink2):
  Can't generate this block in mode 'qt_gui'

See here:

As the post says the fix is easy but being a total newbe it took me a 
while to realize the error and then to find the fix.

Might be worth a note in the web page errata or in the FAQ.  I'm sure 
this issue will come up in other lessons as well.
