Hi all,
I'm trying a sort of a 'hack', but it doesn't work so far. What I want to do is
to add a method to the class in my custom block, and make this method available
in Python (the top_block.py). Without knowledge of SWIG I just tried the
following things (where ZZZ is the name of my block):
1) Add the method protoype to ZZZ.h
2) Add the method protoype to ZZZ_impl.h
3) Implement the method in ZZZ_impl.cc
4) Empty the build/swig folder to force a swig rebuild
5) Run make again
When running top_block.py I get the following errors (apparently my goal is not
that simple):
Traceback (most recent call last):

Anybody knows what I have to add/change to get this working? Maybe something in
the __init__.py file? If so, how do I generate the corresponding .pyc and .pyo
files?
Best regards,
Jeroen
