Re: Cmake cannot find GNU Radio package

[Marcin Puchlik]

Hi Marcus,

Firstly, thanks for the response. I am using VM image which contains pre-installed GNU Radio, you can find it here: https://github.com/bastibl/instant-gnuradio

The reason behind using this image is that I am experimenting with GNU Radio and its dependencies (its kinda testing environment for me). By saying PPA I mean using standard repositories (sorry for the misunderstanding). I tried removing the old GRC installation by typing:

 sudo apt remove gnuradio 

then install it again by typing:

sudo apt install gnuradio=3.8.1.0\~rc1-2build2

Installation process was successful and I can run GNU Radio companion GUI but I do not know why during compilation process, cmake cannot find the GNU Radio. What's more, I was looking for those files:

    GnuradioConfig.cmake
    gnuradio-config.cmake

.. but couldn't find them on my machine. Does installation from standard repositories support building OOT modules or do I have to build GNU Radio from source or using PYBOMBs? 

On the other VM I have GNU Radio installed using PyBOMBs and those files exist and everything works fine.

Hi Marcin,

any particular reason to use the PPA? Ubuntu 20.04 comes with GNU Radio 3.8.1.0 "out of
the box".

Generally, that line works just fine...


Best regards,

Marcus
