Hi everyone,
I've just joined the list and I'm trying to execute a flow in GRC on an RPi3 accessed via a remote desktop connection (I need to run it headless because I'd like to use it for radio-astronomy with an SDR). The flow is extremely simple (just an osmocom source and the WX GUI FFT sink, I'm trying to test the setup before doing anything).
I did pass the first error, by setting
in
~/.gnuradio/config.conf but got
C++ assertion "m_window" failed at ../src/gtk/dcclient.cpp(2043) in DoGetSize(): GetSize() doesn't work without window when running the flow. Googling for it revealed a
workaround 2 years ago (downgrading Python) and
another message on this list about the QT widgets that will replace the WX ones.
So I replaced the WX GUI FFT sink with the QT Frequency Sink and now I get a different error (and no output):
Executing: "/home/pi/top_block.py"
linux; GNU C++ version 4.9.1; Boost_105500; UHD_003.007.003-0-unknown

Traceback (most recent call last):

return getattr(self._tb, name)
AttributeError: 'top_block_sptr' object has no attribute 'top_layout'
I would appreciate some help here for choosing the recommended way to approach this (if possible at all).
Many thanks,
JL
