RE: Use C++ functions block in python

[COURANT Frederique - Contractor]

Thanks Marcus for your help.

I'm actually using GNU Radio 3.8.
I would like to have more information about swig please.
I need to create swig interface and use this command swig -c++ -python 
ligneretard.i or I need to go in swig file and create build folder for 
compiling ?

Thanks.

Best regards.

Fred

Dear Fred,

assuming you use GNU Radio 3.9:
when you look into your OOT's python/ folder, you'll find a bindings/ 
subfolder, in which there are C++ files for each of the blocks you wrote. 
You'll have to add the function you want to call from Python there! GNU Radio 
ships with bindtool, which helps with that!

assuming you're using GNU Radio 3.8:
You'll find that SWIG should be generating wrappings for you that should just 
work, if your methods are GR_API.

We'll need your verbatim error message if we are to help here!

Best regards,
Marcus
