Hi Marcus, Running gnuradio-config-info -v returns the following: *v3.8.2.0-112-ge20ffa3c*
My PYTHONPATH is as follows: /usr/local/lib/python3.6/dist-packages /usr/lib/python2.7 /usr/lib/python2.7/plat-x86_64-linux-gnu /usr/lib/python2.7/lib-tk /usr/lib/python2.7/lib-old /usr/lib/python2.7/lib-dynload /usr/local/lib/python2.7/dist-packages /usr/lib/python2.7/dist-packages /usr/lib/python2.7/dist-packages/gtk-2.0 /usr/lib/python2.7/dist-packages/wx-3.0-gtk3 I should also mention that my approach to date has been to use PyBOMBS to install GNU Radio, after installing UHD driver v3.15.0.0 from source. However, both times I have attempted this, the PyBOMBS installer has asked me whether I want to rebuild UHD from source or keep the existing binary. When I choose "keep existing", the installer crashes out with an error message (both times). Brendan. On Mon, Apr 19, 2021 at 11:58 PM Marcus D.
