Re: GNU Radio 3.7 on Ubuntu 20.04
Hi,
I've been playing around with docker these last days, and I got a running
3.7 on an Ubuntu 18.04 and compiled some OOTs. You may want to check my
repo: https://github.com/git-artes/docker-gnuradio (although it's similar
to what Johannes suggests).

Problems with Correlation Estimator in GNURadio
Hi! I have been trying to use the packet communication examples under gr-digital in GNURadio(v 3.7.14.0) on ubuntu machines with LimeSDR Mini for over the air communication. I am using the usrp_packet_tx.grc and uspr_packet_rx.grc to transmit and receive BPSK modulated packets respectively. I have modified these examples for LimeSDR Mini by including LimeSDR source and sink blocks and setting up the parameters. Now, I am running TX on one machine and RX on another machine tuned to same frequency. However, when I keep the gain values for RX low since the distance between TX and RX is few feet and eliminating the possibility of RX saturation, the packets are not being detected, while for higher gain values packets get detected but the correlation start tags are tagged before the position of estimation tags. I am not too sure if that's how it is suppose to work. Moreover, even after being detected the packets are not decoded and I receive following message on console: INFO: Parser returned #f I think this is due to either incorrect header decoding or incorrect packet detection which freezes the header/payload demux block in the flowgraph. Also, even for very few packets that are decoded, the header is incorrect so why does the packet even gets decoded? Is there a way to work around this problem? Can we use some other block for packet detection? Any suggestion or help is highly appreciated. Thanks in anticipation SG
Re: GNU Radio 3.7 on Ubuntu 20.04
Hi all,
we all saw the Python clock [0] run out on 2020-01-01 after over 10 years.
Also, Maitland Bottoms had to add GR patches to switch from Qt4 to Qt5
for GR 3.7 even earlier to be able to get GR3.7 into newer Debian
versions. Apps are not accepted to the repos if they run with Qt
versions < 5.
All in all, new systems require new software. In this case GR3.8.
If you really need a GR3.7 install, this worked for me:
`sudo docker run --rm -it --net=host --env="DISPLAY"
--volume="$HOME/.Xauthority:/root/.Xauthority:rw"
`. cf [1]
At least I could open and run flowgraphs and run UHD commands. I used
GR3.8 from `ppa:gnuradio` though the docker command should work as well.
USB devices might be another adventure.
You probably want to set up a new container with the latest GR3.7 release.
Cheers
Johannes

iio Block Errors (WSL) Ubuntu 20.04 LTS
I am running a Windows 10 system where I have installed the Windows
Subsystem for Linux running Ubuntu 20.04 LTS.
I followed the steps outlined here:
http://wiki.analog.com/resources/tools-software/linux-software/gnuradio
After doing the steps outlined above, I ran into the following error.
·Traceback (most recent call last):
·File
"/home/jameshayek/GNURadio-Projects/FMReceiver/Simple_FM_Receiver.py",
line 35, in
·from gnuradio.qtgui import Range, RangeWidget
·File "/usr/lib/python3/dist-packages/gnuradio/qtgui/__init__.py", line

·from .qtgui_swig import *

line 13, in
·from . import _qtgui_swig
·ImportError: libQt5Core.so.5: cannot open shared object file: No such
file or directory
I assume this is an issue with mapping the location of swig, so copied
the recursive directory to the gnuradio folder as the lesson said if
there is a swig import error. Still no luck.
I also thought it was an issue with the qt5 library, so I ran "sudo
apt-get install -y qt5-default"
But still no luck.
/Is this an issue with Ubuntu 20?/
/

My exact steps are shown below.
1.Moving Post-Install to Pre-Install:
oFor Python 3.8 I initially exported the following location to $PYTHONPATH
§export PYTHONPATH=$PYTHONPATH:/usr/lib/python{PYTHON VERSION}/{site or
dist}-packages
·export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python3.8/dist-packages/
oI used the python3.8 folder since GNC > About showed Python 3.8
oI then noticed I must have added the wrong PATH, because find resulted
in: “/usr/lib/python3/dist-packages/gnuradio”
oI re-ran the “export” command to include what “find” returned.
2.Installing all “apt install” dependencies:
osudo apt install libxml2 libxml2-dev bison flex cmake git libaio-dev
libboost-all-dev
osudo apt install liborc-dev
osudo apt install swig
§I was under the impression this was not needed for 3.8; however I did
have it installed as a failsafe.
osudo apt install bison flex cmake git libgmp-dev
oOther stuff that I didn’t need but installed anyway
§sudo apt install libavahi-common-dev libavahi-client-dev
§sudo apt install libusb-1.0-0-dev
§sudo apt install doxygen
3.Building from source:
olibiio
§git clone https://github.com/analogdevicesinc/libiio.git
§cd libiio
§cmake ./
§make
§sudo make install
§cd ../
olibad9361-iio
§git clone https://github.com/analogdevicesinc/libad9361-iio.git
§cd libad9361-iio
§cmake ./
§make
§sudo make install
§cd ../
ogr-iio
§git clone -b upgrade-3.8 https://github.com/analogdevicesinc/gr-iio.git
§cd gr-iio
§cmake ./
§make
§sudo make install
§cd ../
§sudo ldconfig
4.Because it seems like I have a swig import issue, I copied the
directory to the gnuradio folder
osudo cp -r /usr/local/lib/python3/dist-packages/iio/
/usr/lib/python3/dist-packages/gnuradio/

My $PYTHONPATH has the following locations:

Any advice as to what went wrong?
