Re: GNU Radio on WSL 2 Debian

Hi Henning - I know next to nothing about Windows but I do use Debian 10. So my first guess would be you didn't install the drivers and libraries for the RTL dongle - or the software to connect the RTL device to gnuradio, namely

  sudo apt-get install rtl-sdr
  sudo apt-get install librtlsdr-dev
  sudo apt-get install gr-osmosdr

-- Cinaed

Hello all,

I installed GNU Radio on Debian with WSL 2 on my Win 10 Laptop.

Procedure:

Install WSL 2 (I use Debian instead of Ubuntu): https://www.omgubuntu.co.uk/how-to-install-wsl2-on-windows-10

Install VcXsrv: https://techcommunity.microsoft.com/t5/windows-dev-appconsult/running-wsl-gui-apps-on-windows-10/ba-p/1493242

Install Gnu Radio and other needed packages:

sudo apt-get update

sudo apt-get upgade

sudo apt-get install gnuradio

sudo apt-get install libgnuradio-osmosdr0.1.4

sudo apt-get install xterm

sudo apt-get install mesa-utils

export LIBGL_ALWAYS_INDIRECT=0

glxgears works fine, so openGL should not be a problem.

The flow graph I stole from here: http://www.stargazing.net/david/GNUradio/RTLFMstations.html

Afterwards I adjusted the frequency and executed the flow graph. I expected additional windows like in this video (https://youtu.be/gHhS90dQ-ZI) but only a really small window opened for a few seconds and closed again.

This happens with all flow graphs I have composed. Seems to be a general problem. Running flow graphs with python leads to a Segmentation fault.

Any ideas how to fix this?

Here is what the log says (sometimes the return code is missing):
