Hi,
the error comes up when you try to `import satmisc_python`. This is the
Pybind11 Bindings part of your module.
Fortunately, the bindings exist and are found. Also, the library
`libgnuradio-satmisc.so` exists. This is the file where your blocks get
compiled into.
However, this library is looking for a symbol `zmq_strerror` that it
can't find. You probably didn't link your module against ZMQ.
This is probably missing in your module:
https://github.com/gnuradio/gnuradio/blob/78d89e1466864d305fbb8a5b25a7e1e94efc18c4/gr-zeromq/lib/CMakeLists.txt#L31
Cheers

I do not know exactly where this error comes from and would much
apreciate any hints on how to fix this.
