Hi everyone,
I think I'm finally getting the hang of this, I seem to have gotten almost
everything in my project working thanks to Gustavo's latest pybindgen patch.
One of the remaining things I am having difficulty with is putting annotations
on member variables of a class. I have something of the form:
class foo{
<stuff>
};
class baz {
public:
foo* var;
}
The error I am getting from pybindgen is "WrapperWarning: Return value '::foo
*' error (used in baz::var [variable]): TypeConfigurationError('Either
caller_owns_return or self.reference_existing_object must be given')
I know that the issue is that I need to stick an annotation on there. Since
the pointer is allocated and tracked by the underlying C++ code, I'm pretty
sure that I need to put reference_existing_object on it. I've tried inserting
"{'reference_existing_object' : 'true'}" into the global_annotations table, and
also inserting it into the parameter_annotations["return"] dictionary. For
kicks, I even tried both at once. No matter what I do I can't get rid of the
error, or see it show up in my final build, which leads me to believe there's
something I'm missing. I went and looked up the documentation for
reference_existing_object, but of course none of their examples show how you
could use it on a member variable. What am I missing?
Thanks,
Ben Fitzpatrick
