pivy: SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

[looooo]

Not sure if this is an issue with swig, but with python3.10 I must define PY_SSIZE_T_CLEAN before including Python.h. Is there a way to do this with swig?

ref.: coin3d/pivy#88

%begin %{
#define PY_SSIZE_T_CLEAN
%}

Thanks

Can this be generated automagically by swig?

This is required on this python version, generating code without the define is broken.

It is for swig-4.1.0, see abc8e0b and issue #2277.
