[C++-sig] problems with embedded python and pure virtual functions

[Birgir Sigurjonsson]

Hei here is the python code:

 from import_framework import AbstractLoader, AbstractLoaderFactory

print 'Python running: --> Ascii135Loader script'
class Ascii135Loader(AbstractLoader):
    def __init__(self):
        super(Ascii135Loader, self).__init__()
        print self.__init__
    def load_impl(self):
        print 'load_impl -- doing som hard work'
        return True


class Ascii135LoaderFactory(AbstractLoaderFactory):
    def __init__(self, key):
        super(Ascii135LoaderFactory, self).__init__(key)
        print  'Python running: 4--> Ascii135LoaderFactory(AbstractLoaderFactory) __init__'
        print self.__init__

    def make(self):
        print  'Python running: 5--> Ascii135LoaderFactory::make'
        return Ascii135Loader()

register_this = Ascii135LoaderFactory("Ascii135")

And I can see that the AbstractLoader constructor is called because I have
a print out there

Best regards,
Birgir.
