I expose the return type of a C++ function that is a pair of strings with
the following snippet:
to_python_converter<
std::pair<std::string, std::string>,
Converter>();
Later, I have a unrelated C++ range type:
typedef std::pair<const std::string*,const std::string*> range_t;
which I export as:
class_<range_t>("range")
.def("__iter__" , range(..., ...));
scope().attr("allitems") = object(ptr(&R));
where R is of type range_t
in python, allitems can be iterated over.
The only issue is I get the following warning:
/usr/lib64/python3.4/importlib/_bootstrap.py:321: RuntimeWarning:
to-Python converter for std::pair<std::string const*, std::string
const*> already registered; second conversion method ignored.
Is there a way to avoid this warning?
