3 years ago You mention that you have Gnuradio "3.9.2.0" installed. The output of the script mentions version "3.8.1.0" though. Are you sure there are no Gnuradio 3.8 files installed on that computer?

3 years ago Well I am not entirely sure this is a fresh ubuntu installation on a virtual machine (after failing the installation before) with no other programs installed the first thing I did was commence the install of gnuradio.
sudo add-apt-repository ppa:gnuradio/gnuradio-releases I installed GNURadio from the releases repo using that command and then apt-get update as doing the default command of apt-get install gnuradio would install the older 3.8 version
The command gnuradio-config-info --version outputs 3.9.2.0
I then proceeded with the installation of gr-iridum.
I then received another error saying that the library "iridium" was not found. So I proceeded to type this command export PYTHONPATH=/usr/local/lib/python3/dist-packages Which solved the issue but then brought about another one ImportError: No module named osmosdr
So I went ahead and typed sudo apt-get install gr-osmosdr
But now I'm receiving that other error that I've put as a screenshot.
I'm sorry if I've made a beginners mistake here and I'm wasting everyone's time, I found this project from a Youtube tutorial and they did not encounter any of these sorts of errors that I encountered so perhaps I've just done something fundamentally wrong ?

3 years ago The main issue here is the version hell that gnuradio is putting us through :/ This is not at all a beginners mistake.
We will have to look into what Ubuntu really does and try to reproduce your results. Might take some time.... I'll have to ask for a bit of patience until this can be figured out.

3 years ago The problem is that gr-osmosdr is installed from the Ubuntu 20.04 repositories. It depends on gnuradio-3.8 and when running apt install gr-osmosdr a gnuradio 3.8 installation is pulled in together with it. This causes the master branch of gr-iridium to not work anymore as the system now has a mix of gnuradio 3.8 and 3.9 installed.
Currently there are two options for you:
maint-3.8 branch of gr-iridiumgr-osmosdr from the Ubuntu repositories. Build and install gr-osmosdr as described here: https://osmocom.org/projects/gr-osmosdr/wiki

3 years ago While the two options @schneider42 mentioned are probably the best ones, there is a third one:
If you follow the commands in the the README of https://github.com/Sec42/sec-gr/ you should end up with a working gnuradio/gr-iridium build in a local prefix. Be warned that this will take around ~20G of space and likely a few hours of compile time depending on your hardware.

3 years ago I just wrote some code which allows to use soapy instead of osmosdr. This hopefully works out of the box with gnuradio-3.9 without the need of installing gr-osmosdr.
You can check whether soapy works for you by running "SoapySDRUtil --find" with the SDR plugged in. If it can see your SDR you might be able to use it.
To try it, checkout & build the "soapy" branch, and then run:
iridium-extractor -D 4 examples/rtl-sdr-soapy.conf
If anyone tries this, please add a comment wether that works for you or not.

While the two options @schneider42 mentioned are probably the best ones, there is a third one:
- install everything(gnuradio-3.9, gr-osmosdr & gr-iridium) from source with pybombs

I follow the README in the Github link and it works on Ubuntu 20.04 with gnuradio-3.9! It takes around 1-hour with i7-6600U processor.

I have gnuradio installed version 3.9.2.0
(Note I also had to install osmosdr manually (apt-get install gr-osmosdr) and I also encountered the issue where I enter the python path command as described in issue 5. (Module iridium not found).
Ubuntu version was 20.04.2.0 This is a fresh ubuntu installation and I installed gnuradio from the gnuradio-releases repository as instructed in other issues)
