[SciPy-User] Scikits.sparse build issue

[Anand Patil]

Hi all,

I was excited to notice scikits.sparse this morning. I've been waiting
for something like that to appear for a while now! I'm trying to
install the HG head on a Mac, with EPD 7.0-2 and Numpy 1.5.1. I've
installed SuiteSparse from MacPorts.

First, the following line from cholmod.pyx doesn't work with MacPorts'
SuiteSparse:

   cdef extern from "suitesparse/cholmod.h":

It needs to be

   cdef extern from "ufsparse/cholmod.h":

Having done that, I get a sequence of errors like the following:

python setup.py build
running build
running build_py
running build_ext
skipping 'scikits/sparse/cholmod.c' Cython extension (up-to-date)

‘__pyx_f_7scikits_6sparse_7cholmod__py_sparse’:
scikits/sparse/cholmod.c:1713: error: storage size of ‘__pyx_t_10’
isn’t known

I've never used Cython and am having a hard time figuring this out.

Thanks in advance for any help,
Anand
