[Chicken-users] C_word type / Cython (warning: passing argument 2 from incompatible pointer type)

[David Dreisigmeyer]

Here's my setup:

OSX 10.6.6
Chicken 4.6.0
Python 2.7.1
Cython 0.14

** The Chicken part:

What type is C_word?  The only thing I see is this in chicken.h

#ifdef C_SIXTY_FOUR
# define C_word                   long
# define C_u32                    uint32_t
# define C_s32                    int32_t
#else
# define C_word                   int
# define C_u32                    unsigned int
# define C_s32                    int
#endif

but I get the following warning:

warning: passing argument 2 of ‘CHICKEN_eval_string’ from incompatible
pointer type


** The Cython part:

I'm trying to use this with Cython, so I have (in my *.pxd):

ctypedef long C_word (Note: I tried ctypedef int C_word also.)

cdef extern from "chicken.h":
    int CHICKEN_eval_string(char *, C_word *)

cdef inline C_word C_chick_eval_s (char *IN_STR):
    cdef C_word OUT_RESULT
    status = CHICKEN_eval_string(IN_STR, &OUT_RESULT)
    if (status == 0):
        print "Chicken evaluation failed"
    elif (str(OUT_RESULT) == '#<unspecified>'):
        pass
    else:
        print OUT_RESULT
    return OUT_RESULT


Thanks!
