Re: GNU Radio gr-osmosdr on Ubuntu Installation Error; Kali Successfully Installs but Can’t Run

[Jessica Chen]

Hi all,

Thank you for the feedback! I've managed to figure this out on my own. Essentially, I followed this guide that another user put together a couple months ago: https://lists.gnu.org/archive/html/discuss-gnuradio/2020-09/pdfNp27msymbN.pdf

NOTE: This guide uses GRC 3.8. Currently, gr-osmosdr requires GRC 3.9 and above.

In short, I followed this process for installation to get a working GRC 3.9 with osmocom and HackRF One compatibility:

• Completely erase disk and install Ubuntu 20.04 LTS via bootable USB
• install GR 3.9 dependencies
• See: https://wiki.gnuradio.org/index.php/UbuntuInstall#Install_the_Pre-Requisites
  
• PPA install gnuradio 3.9
• install librtlsdr from source
• https://github.com/librtlsdr/librtlsdr
• install gr-osmosdr from source
• cmake with /usr prefix: ```cmake -DCMAKE_INSTALL_PREFIX=/usr ../```
• install libhackrf from source (for interfacing with HackRF One)
  
• git clone https://github.com/mossmann/hackrf.git
• instructions: https://github.com/mossmann/hackrf/wiki/Operating-System-Tips

The main differences with this guide and my original from-source installation are its installation of librtlsdr and its use of the /usr prefix with gr-osmosdr. To be honest, I'm not sure which one was the key point here. At the moment, the osmocom sink and source show up successfully, but I'm still running into problems with blocks (though I don't know whether the source of these problems is the /usr prefix or GRC 3.9 or both).

Thanks,

Jessica

Hi,

To be clear, there is no branch named "3.9" in of the gr-osmosdr git
repository because the current master branch covers gnuradio-3.9.  Your
suggestion that gr-osmosdr has not been ported to gnuradio-3.9 is wrong.
