在我的安装中,numpyarrayobject.h位于…/site- packages/numpy/core/include/numpy/arrayobject.h。我编写了一个使用numpy的普通Cython脚本:
arrayobject.h
…/site- packages/numpy/core/include/numpy/arrayobject.h
cimport numpy as np def say_hello_to(name): print("Hello %s!" % name)
我还有以下distutils setup.py(从Cython用户指南中复制):
setup.py
from distutils.core import setup from distutils.extension import Extension from Cython.Distutils import build_ext ext_modules = [Extension("hello", ["hello.pyx"])] setup( name = 'Hello world app', cmdclass = {'build_ext': build_ext}, ext_modules = ext_modules )
当我尝试使用构建时python setup.py build_ext --inplace,Cython尝试执行以下操作:
python setup.py build_ext --inplace
gcc -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-madd \ -fno-common -dynamic -DNDEBUG -g -Os -Wall -Wstrict-prototypes -DMACOSX \ -I/usr/include/ffi -DENABLE_DTRACE -arch i386 -arch ppc -pipe \ -I/System/Library/Frameworks/Python.framework/Versions/2.5/include/python2.5 \ -c hello.c -o build/temp.macosx-10.5-i386-2.5/hello.o
可以预测,这找不到arrayobject.h。如何使distutils使用numpy包含文件的正确位置(而无需让用户定义$ CFLAGS)?
用途numpy.get_include():
numpy.get_include()
from distutils.core import setup from distutils.extension import Extension from Cython.Distutils import build_ext import numpy as np # <---- New line ext_modules = [Extension("hello", ["hello.pyx"], include_dirs=[get_numpy_include()])] # <---- New argument setup( name = 'Hello world app', cmdclass = {'build_ext': build_ext}, ext_modules = ext_modules )
