Re: [GNU Radio 3.8] Error loading modules on E310

[Philip Balister]

What version gnuradio is installed on the E310?

$ gnuradio-config-info -v

There should be a cmake variable to set the python interpreter version.
That might be better than trying to point at libraries in the sdk.

Try -DPYTHON_EXECUTABLE=python (or path to python in the sdk)
