If you just need your Python interface to support calling those function
pointers, not adding new functions in Python, it's relatively easy. In
particular, boost::python::make_function takes a C++ function pointer
and returns a callable Python, so you can do something like this:
namespace bp = boost::python;
bp::object foo_get_func1(foo & self) {
return bp::make_function(self.func1);
}
bp::class_<foo>("foo")
.add_property("func1", foo_get_func1)
;
I haven't tested that snippet, so it may need some tweaks. But
hopefully it will get you started.
