I keep getting this error: #warning "Using deprecated NumPy
API, disable it by #defining NPY_NO_DEPRECATED_API" and a bunch of
undefined variables when comping cython code with numpy
I am new to cython and numpy and I am having trouble getting a *.pyx extension
to compile with this in the header:
from __future__ import division
import numpy as np
cimport numpy as np
DTYPE = np.int
ctypedef np.int_t DTYPE_t
I complie to C code using:
cython -a montcarl.pyx
And it seems to work fine.
I then attempt to compile using:
gcc -I /Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/
Python.framework/Versions/2.6/include/python2.6 -I /usr/local/lib/
python2.7/site-packages/numpy/core/include -shared -pthread -fPIC -
fwrapv -O2 -fno-strict-aliasing
-o montcar.so montcarl.c
And I get a bunch of undefined variables:
spoust-m:old spoust$ gcc $CFLAGS -o montcar.so montcarl.c

Undefined symbols:
"_PyLong_AsLong", referenced from:
___Pyx_PyInt_AsLong in ccvkIDLQ.o
___Pyx_PyInt_AsLong in ccvkIDLQ.o
...
Any ideas on how to get this to compile and how to get rid of these
numpy undefined variables? The cython guys directed me here.
