所以我一直在尝试运行一个简单的脚本,我在 MacOS 10.11.5 (El Capitan) 下使用 Cython 0.24 将 C 代码合并到我的 python 项目中。我使用 PyCharm 和 Python 版本 2.7.10 编辑代码。我的 setup.py 看起来像这样
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
from Cython.Build import cythonize
import os
dirs = [os.getcwd()]
ext = [Extension("hello_world",
include_dirs=dirs,
sources=["mymodule.c","hello_world.pyx"],
depends=["mymodule.h"])]
setup(
name = "testing",
cmdclass={'build_ext' : build_ext},
ext_modules = cythonize(ext)
)
它很好地生成了 hello_world.c 并且还生成了一个构建目录和一个 *.so 文件 *.pyx文件中包含如下定义,明显符合mymodule.h中的定义
cdef extern from "mymodule.h":
cdef float MyFunction(float, float)
我尝试了此处建议的解决方案:"'cc' failed with exit status 1" error when install python library
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
上面代码中的自定义扩展解决方案来自这里: Compiling Cython with C header files error
我还尝试了此处建议的 MacOS 特定解决方案,但这只是绝望:https://github.com/wesm/feather/issues/61
export MACOSX_DEPLOYMENT_TARGET=10.11
但不幸的是,它仍然无法正常工作。我确信 Cython 工作正常,因为我事先实现了一些功能,并且当实现在 Cython 中时可以调用它们。它只包括实际的 C 代码,这个问题对我来说就是在这里发生的。
我希望有人能帮助我,在此先感谢!
编辑: 我收到以下错误消息

最佳答案
我自己解决了。问题实际上不在我在这里发布的代码中,而在调用该函数的代码中。 我有台词
import pyximport
pyximport.install()
还是调用hello_world中的函数之前的代码。这似乎导致了问题。当我删除这两行时,可以正常调用该函数。
