2 years ago At a high level, it looks like gr-lora_sdr's CMake code was not really updated to align with GNU Radio 3.8; the version of cmake/Modules/UseSWIG.cmake that it has is from the GNU Radio 3.7 era. Updating that (probably a big job, and I'm not saying it's your job) would almost certainly improve things.
At a lower level, this is the key error:
TypeError: Unicode-objects must be encoded before hashingwhich happens when executing the Python code from these lines.
I think that is ultimately a problem coming from using Python 3 with code that was originally written to work with Python 2. That code snippet probably needs to be upgraded to be compatible with Python 3 by doing what the error says and .encode()ing the string before hashlib.md5() is evaluated. But if that were the full problem, then I wouldn't think this would work for anybody with Python 3, yet gr-lora_sdr claims Python 3 compatibility so I don't know what is unique about your setup. Perhaps is has to do with having Unicode characters in your file paths.
