gr-iio Update for GnuRadio 3.8.x

master has not been upgraded to 3.8 yet. This branch should work fine though: https://github.com/analogdevicesinc/gr-iio/tree/upgrade-3.8

Thanks for the link to the gr-iio 3.8 upgrade.  I have it running on 3.8 now with a Pluto. It compiled and installed just fine.  Thanks for your help

Dennis.

Hi travis, 

stil getting this on both 18.04 and 19.02, gnuradio 3,8 and 3,,9, what ever i do cant get a build on gr-iio, even on the 3.8 branch, am i missing something vital.  did the libiio and liad get updated too, how about an apt full binary build on a sub branch?
