Unfortunately, that doesn't work either :/ (Same error message, no matter which incantation, Cython 0.15.1+) Thanks for the feedback.

Re: [Cython] Correct way of defining enums
The problem was with the definition of PyArray_SearchSorted, namely cdef object PyArray_SearchSorted (ndarray, object, NPY_SEARCHSIDE) The problem was that NPY_SEARCHSIDE wasn't defined as a type, so it was treating that as the argument name (implicitly typed to be object). https://github.com/cython/cython/commit/5ba30c45c7d3478f7b7d0490e720fb0a184c6050 There should probably be at least a mode to give warnings for untyped arguments (and return types) of cdef functions. - Robert 2011/11/29 Stéfan van der Walt : > On Tue, Nov 29, 2011 at 9:08 PM, Greg Ewing > wrote: >> Did you try both together?
