GNURADIO 3.10 : PlutoSDR (and all Industrial I/O) blocks missing?

Question

I'm new to Gnuradio and recently I wanted to use the software with a Adalm Pluto SDR, which rely on the gr-iio module.

According to the 3.10 gnuradio changelog, analog devices website and Josh Morman FOSDEM 2022 slides, now the gr-iio module is integrated in the gnuradio software (as well as the gr-pdu).

However, while I'm able to see the PDU tools in the available blocks in gnuradio companion, I cannot see any Industrial I/O related blocks.

In /usr/share/gnuradio/grc/blocks, there is no block that contain iio in their name.

My Gnu Radio Companion version is 3.10.9.2, and I'm using fedora 40

Do you have any idea on why I don't have those modules ? Do I need to install something else ?

Thank you in advance for your help,

Hugo

I'm on Fedora 37 still, so things may be different but I just encountered the very same issue: gr-iio is missing.

It turns out that gnuradio looks for libiio and libad9361-iio during the compilatiaon process and includes gr-iio if these are found. In case they are missing, gr-iio is no built and is therefore missing from the rpm shipped by Fedora.

My solution was to install the two libraries and then to recompile and reinstall the gnuradio packages (dnf download --source gnuradio, rpmbuild and then install).

I don't feel comfortable submitting a bug report to Fedora since I'm on an old version, but I will do that when I upgrade if the problem persists. I don't know of an easy/clean way to install gr-iio separately from the gnuradio core unfortunately...
