Re: [boost] Python: overloading static methods

I think the problem is that you are casting to a pointer to member
function, instead of a simple pointer to function.  The functions you are
trying to access are static, and so are not bound to an object instance.

I think if you change the .def calls to something like the following
you'll get past the compiler error:

hello_class.def((void (*)(void)) hello::over, "over");
hello_class.def((int (*)(int)) hello::over, "over");
