Pybombs Install Issue

[altonbill]

Hello, I am trying to install gr-ieee-15-4 via pybombs but am running into this error. From what I can tell it has something to do with the newer versions of gnuradio. Is there a way to specify an earlier release with pybombs like GR3.8?

I guess PyBombs is no longer maintained. You'd either have to update the PyBombs receipt (should be simple: https://github.com/gnuradio/gr-recipes/blob/master/gr-foo.lwr#L24) or use another install method.

Okay, sorry if this is a naive question. I was able to install it by source, but gnuradio couldn't find the blocks. I was hoping the pybombs install would work because I couldn't find the ~/.gnuradio/config.conf where I could point it toward where the new blocks had been built. Is there a trick to where to build the libraries from source so gnu-radio can find them? Right now I have a working base gnuradio install from pybombs, but I'm not sure where to put everything

[bastibl]

You can just create the file if it doesn't exist. You could also do gnuradio-config-info --print-all. It should list where it searches for configs. (See also the other switches to the command to make sure your configuration is picked up.)

Okay, it's 90% of the way there now. I've got gnu radio 3.8 to find the blocks installed from the maint-3.8 branch in Ubuntu 18. For some reason, the blocks path were in a file called grc.conf, but after adding the paths there, I can see the blocks now after I built the Phys layer blocks. However, it seems like python is picking up the ieee802_15_4 because I am seeing this message `During handling of the above exception, another exception occurred:

This is not the actual error (During handling of the above exception...) I assume you either did not set the library path or python path correctly.
