Re: Problem building OOTs with GR 3.9.3.0 PPA package

[schneider]

Hi

I'm experiencing the same issue with our OOT. I've got pybind11-devc
2.5.0-4~ubuntu20.04.1~ppa1 installed from the PPA.

If I also install gnuradio-dev from the PPA, I get the error mentioned
by Daniel. If I build GNURadio 3.9.3 from source (same pybind version as
mentioned above), the error goes away.

It's not obvious to me what happening. My first questions would be: Was
gnuradio-dev in the PPA built using the pybind11 version which is
available in the PPA? Does pybind11 version in the PPA need an update?
