You need to declare these members as function pointers, i.e.

   cdef extern from "Rectangle.h":
     ctypedef struct c_Rectangle "Rectangle":
       ...
       int (*getLength)()
       int (*getHeight)()
       int (*getArea)()

The error message you get in this case is a bit confusing.
I'll see if I can improve it in a future release.
