Gnuradio 3.8 #35

Open miguellopes opened 4 years ago

miguellopes commented 4 years ago

Added compatibility with Gnuradio 3.8 and python3

alphafox02 commented 3 years ago

Thought I'd try this on 20.04 with GR 3.8/Python3, however I ended up with issues trying to generate the example blocks. Is it expected a user should be able to compile all blocks and use the example flow graphs provided?

Looking closer it appears most of the heir blocks are not generating properly with my gnuradio 3.8.1 build. I don’t suppose you’re still monitoring this or have time for a quick test on a distro I’m working with?

miguellopes commented 3 years ago

@alphafox02, I currently don't have the time to look at it, but from gnuradio 3.8 the hier_blocks are now YAML files and not the XML ones. I checked if the YAMLs were working on GR 3.8.2 and they aren't so not sure if this is useful to you

alphafox02 commented 3 years ago

Thank you for taking a quick look. I sat and messed with it for awhile, opening each .grc file and having a look. There seem to be unique errors throughout and I’m not that familiar with the differences in GR. I took a break for now, still would be a cool project to use for LTE.
