Does not build with GNU Radio 3.9

[rgov]

GNU Radio 3.9 moved from SWIG to PyBind11, which might explain this build error (on macOS):

GNU Radio 3.9 OOT Module Porting Guide

Commit that removed SWIG from GNU Radio: gnuradio/gnuradio@9f60861

[adamhorden]

I have this fixed in:

analogdevicesinc/gnuradio#4

💥

This needs to be merged into gr-iio. I created the PR on the GNU Radio fork as IIO was supposed to be upstreamed in GNU Radio release v3.9.0.0 but this has not happened.

The changes from that need to be merged into gr-iio as the OOT module.

I will create a PR to bring my changes across 🤓 .

[rgov]

Awesome. Do you know what is going on with master vs upgrade-3.8 here?

[adamhorden]

@rgov I am not sure on that. I am just an end user, using GNU Radio with Analog Devices Plutos.

I have started a work in progress pull request here 🤓 :

#96

[anilgurses]

Is there any update?

[adamhorden]

@anilgurses this has been superseded by:

gnuradio/gnuradio#4277

We are currently working on bringing gr-iio in tree. If you compiled that branch from source you would get gr-iio support. We are getting closer every day now to merging this in. Lots of work has happened in the feature/gr-iio branch here 🤓 :
