How to make my SWIG extension module work with Pickle?

Question

I have an extension module for Python that uses SWIG as a wrapper and I try to serialize it with Pickle and I fail =)

1. If anyone has a source of SWIG extension

Answer 1

I had to make a minor change to the accepted answer to make it work for my case. Since the initialization function of my class has some input arguments, I had to add an extra argument *arg to the C.__init(self) function, like so:

    class PickalableC(C, PickalableSWIG):
        def __init__(self, *args):
            self.args = args
            C.__init__(self, *args)

Maybe this is helpful for someone. I hope it is not too trivial.

I posted it as an answer since I cannot comment and learned it is not something you edit a post for.
