Re: PlutoSDR & Mac - iio block issues??

[Glen I Langston]

Thanks
I’ll try that in the future.
However I’m not sure why this is an issue in the first place.  It should
be fixable at the cmake step.

Looking at the link provided in an earlier email, it seems
like part of the problem is the different uses of
site-packages and
dist-packages.

Can that be fixed at the cmake step?

Thanks again,
Glen
