I'm adding a wrapper for the npy_bool type. I've included a file called bool_ops.h which basically contains:

typedef npy_int8 npy_bool_wrapper;

(https://github.com/cowlicks/scipy/blob/swig-sandbox/scipy/sparse/sparsetools/bool_ops.h)

Then I included bool_ops.h and the wrapper npy_bool_wrapper in sparsetools.i and numpy.i where I thought it was necessary. So that the typemaps for the npy_bool type are generated.

TypeError: Array of type 'byte' required.  Array of type 'bool' given

Which is not what I expected because the typemaps for bool type should now be generated. 

Could the order in INSTANTIATE_ALL be the problem? (https://github.com/cowlicks/scipy/blob/swig-sandbox/scipy/sparse/sparsetools/sparsetools.i#L176) 

Why is order important here? I included npy_bool_wrapper where I did because the Numpy C api says npy_bool is an unsigned char. I'm currently trying to reorder INSTANTIATE_ALL to make things work. 

Thanks in advance,
