ieee802_15_4 has no attribute rime_stack

[martinbishopx]

Hey Basti!

I could successfully build the two hierarchical blocks. I had to adjust my library path for the python modules because it could not been found before:

export PYTHONPATH=/usr/local/lib/python3/dist-packages/:${PYTHONPATH}

When I am not trying to run the "transceiver_CSS_loopback.grc I am getting the following error:

<<< Welcome to GNU Radio Companion 3.8.5.0 >>>

The blocks have been found so far. Within the code I was also not able to find the "rime_stack" attribute. Do you have an idea what went wrong? :)

I am not sure if it is important but I am using Ubuntu 20.04 in a VM. I used/built the corresponding branch (maint-3.8 ) for gnuradio compantion 3.8. The building process worked out so far. I also had to connect the lines of the CSS_PHY.grc project, but I guess, even if I made a wrong connection there, this block built should not be the problem here?

Thanks! :)

Did you look at this issue: https://github.com/bastibl/gr-ieee802-15-4/issues/50 ?

Hey Basti! Thanks for the quick response. Unfortunately it did not work. I have swig installed and the two path variables set as follow:

debug@go:~$ echo $LD_LIBRARY_PATH
/home/debug/gr-ieee802-15-4/build/lib/:LD_LIBRARY_PATH

The "libgnuradio-ieee802_15_4.so " is in there as shown below:

debug@go:~$ ls -lisa /home/debug/gr-ieee802-15-4/build/lib/

The PYTHONPATH is also being set as follow:

debug@go:~$ echo $PYTHONPATH
/usr/local/lib/python3/dist-packages/:/usr/local/lib/python3/dist-packages/:

The modules can be successfully imported as shown below:

Swig is also being installed:

debug@go:~$ swig
Must specify an input file. Use -help for available options.

Did I miss a certain path? I am using Ubuntu 20.04 in the default installation setup. One thing that might help and which sounds like I am missing a path, is the following:

When I deactivate the RIME STACK block and try to build it, I get the following error:

AttributeError: module 'ieee802_15_4' has no attribute 'mac'

Thanks for your support! :)

Set the LD_LIBRARY_PATH to the install path of the library (not the build dir). Probably that's /usr/local/lib. Then do sudo ldconfig.

Hey Basti! Thanks for the support! I did not rebuild the project after installing swig. I did it and it worked. Should check the log next time because it mentioned swig is now being installed - wasn't before. Thanks for your help!
