Hi,

I am having problems running a WX GUI FFT Sink, I am getting the following runtime error:

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.
