致命错误：未找到'mymodule.h'文件 - Cython编译无法找到标题

Question

因此，我一直试图获得一个简单的脚本运行，其中我使用Cython 0.24在MacOS 10.11中将C代码合并到我的python项目中.5（埃尔卡皮坦）。我使用Python版本2.7.10编辑PyCharm的代码。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) 
) 

它生成hello_world.c就好了，也产生一个build目录和.so文件 的* .pyx文件的*包含以下定义，这显然是定义相匹配在mymodule.h

cdef extern from "mymodule.h": 
    cdef float MyFunction(float, float) 

我尝试了这里的解决方案建议："'cc' failed with exit status 1" error when install python library

export CFLAGS=-Qunused-arguments 
export CPPFLAGS=-Qunused-arguments 

和自定义扩展小号olution已经在上面的代码来自这里： Compiling Cython with C header files error

我也尝试了MacOS的具体解决方案建议在这里，但那只是绝望：https://github.com/wesm/feather/issues/61

export MACOSX_DEPLOYMENT_TARGET=10.11 

不过遗憾的是它仍然是行不通的。我相信Cython是正常工作的，因为我事先实现了一些函数，并且可以在Cython实现时调用它们。这只是包括实际的C代码，这个问题发生在我身上。

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

Answer 1

我解决它在我自己的。问题其实不在我在这里发布的代码中，而是在调用该函数的代码中。 我行

import pyximport 
pyximport.install() 

仍然在代码调用程序hello_world函数之前。这似乎导致了这个问题。当我删除这两行时，该函数可以被称为很好。
