GnuRadio gr-iio build

Are you able to locate the file by doing the following:

$locate sig_source_f.h

GNU Radio 3.8 requires a specific branch: https://github.com/analogdevicesinc/gr-iio/tree/upgrade-3.8

-Travis

Wow Travis, you nailed it again. gr-iio can be built and installed.

However, gnu-radio now complains that the iio module has no attribute pluto_source.

Could this be related to the rollback of libiio you recommended me to do on a previous ticket last friday?

Cheers

In GR-3.8 we had to put the gr-iio module in a different place, so sometimes the bindings interfere since they have the same module name (iio). I would remove the bindings iio.py file.

-Travis

Then we get some other errors from gnuradio. Sorry but I'm lost here.

What files are in the folder "/usr/local/lib/python3.6/dist-packages/iio/"?

Have you tried re-installing gr-iio once the bindings were removed?

-Travis

The folder "/usr/local/lib/python3.6/dist-packages/iio/" contains files installed by gr-iio (apparent when performing the make install)

I did not remove the bindings because I still want to be able to interface with the pluto through python3, I simply renamed the iio.py file to another name.

I tried to reinstall the gr-iio package after that but to no avail.

Where is libgnuradio-iio.so installed? and is this on path?

-Travis

/usr/local/lib/libgnuradio-iio.so
/usr/local/lib/libgnuradio-iio.so.0
/usr/local/lib/libgnuradio-iio.so.0.3

Any new ideas Travis?

Alternatively - is there a safe software setup you recommend to install both gnuradio and the iio bindings on the same machine (ubuntu version, python version, gnuradio version, ...) without running into installation issues?
