[Cython] Problem with declaring a map with an enum type.

[Brian McAndrews]

I have a C enum type that I'm attempting to put in a C++ map:
Here's what I got:

colors.h:
enum Color
  {
    GREEN,BLUE,RED
  };

val.pyx:
from libcpp.string cimport string
from libcpp.map cimport map

cdef extern from "colors.h":
    cpdef enum _Color "Color":
       GREEN,BLUE,RED

cdef class TestMe:
    cdef public map[string, _Color] vals


I get a compile error (VSC++ 2012)
VAL.cpp(1239) : error C2440: '=' : cannot convert from 'long' to 'Color'
        Conversion to enumeration type requires an explicit cast (static_cast, C-style cast or function-style cast)

The offending statement is this:
    __pyx_t_9 = PyInt_AsLong(__pyx_v_value); if (unlikely(PyErr_Occurred())) {__pyx_filename = __pyx_f[1]; __pyx_lineno = 202; __pyx_clineno = __LINE__; goto __pyx_L1_error;}

In the __pyx_convert_map_from_py_std_3a__3a_string__and_enum__Color function.

The cast from PyInt_AsLong(...) to an enum Color is not specified when using maps.

If I don't put it in a map (just as a member variable), the cast is performed.

Has anyone seen this before?

Thanks,
Brian
