Removing OOT modules from upgraded gnuradio
Hi all! I upgraded to Ubuntu 22.04, and with it upgraded gnuradio to version 3.10. Because of that I need to remove all OOT modules, which didn't succeed when using "make uninstall" as it gives out a swig error due to swig not being used anymore. I also tried using apt-purge without success. Is there a way to remove all oot modules from gnuradio/reinstall a truly clean gnuradio? Thanks, Yotam
Fwd: how to make stream demux block in python
There is a built-in Stream Demux block you could use. Do you specifically need it to be in Python?

Re: how to make stream demux block in python
Right, it's not in 3.8. Here's the implementation in C++ for more recent versions. You could translate this to Python if you want. Note that it's a block (not a sync block) so you implement general_work() rather than work(). https://github.com/gnuradio/gnuradio/blob/main/gr-blocks/lib/stream_demux_impl.cc On Sun, Dec 11, 2022 at 8:24 AM Sumit Agrawal (P19EE207) < agrawal...@iitj.ac.in> wrote: > Hi Jeff, > > I can't see any stream demux block in gnu radio 3.8. > Yes, I need specifically in Python > > > > Thanks & Regards, > Sumit Kumar Agrawal, > Ph.D. (Electrical Engineering) > Indian Institute of Technology, > Jodhpur, Rajasthan-342037 > Mobile No. +91-8410957412 > > On Sun, 11 Dec, 2022, 5:56 pm Jeff Long, wrote: > >> There is a built-in Stream Demux block you could use.

Re: Import error using an OOT
I have attached the 2 files in question. Look at the beginning of
run_response.py. It uses ConfigParser to access the ft8_qso.conf configuration
file.
This line seems to be the problem: my_call = str(parser.get('main',
'my_call_sign')).
But ‘main’ is a section in the ft8_qso.conf file. Why can’t it find ‘main’?

Re: Import error using an OOT
The main method is defined beginning on line 216 and called 4 times on
lines 36-39.
And it appears the configparser is throwing the NoSectionError.
Try commenting out line 36 to see if line 37 throws the same exception.
When you said is has run before, did it run under python3.9?
