Hi,
I am having problems running a WX GUI FFT Sink, I am getting the
following runtime error:
Traceback (most recent call last):

wx._core.PyAssertionError: C++ assertion "m_window" failed at
./src/gtk/dcclient.cpp(2041) in DoGetSize(): GetSize() doesn't
work without window
Is this a know bug? whats the best way to fix it? I am new to
gnuradio.
I'm running gnuradio 3.7.3-4
Kind Regards,
Thil
It's telling you that you haven't defined a window for the FFT. You
can specify no window (iirc) by passing it '[]' or you can look at the
fft.window module, which provides a set of windows you can define.

Tom, you should look again.
This is a "guts of wxPython" thing.
Either there's no Xwindow server running, or they forgot to specify "WX
GUI" in the generate options.
