distutils include_dirs具有相对路径吗？

Question

我有一个C++包，我在前段时间内建立了一个Python扩展。现在我想在distutils下正确组织它。 （使用Python 3.6.2（一个全新的Windows 7安装））这是我的setup.py，到目前为止：

from distutils.core import setup, Extension 

drawbox_module = Extension(
    "drawbox", 
    include_dirs = ['..\Drawbox Library', '..\Drawbox Tools'], 
    sources = ["PyDrawbox.cpp", 'Drawbox.Win.cpp']) 

setup(name="drawbox", 
     version="1.0", 
     ext_modules= [drawbox_module]) 

然而，当我真正尝试建立它似乎忽略了我的include目录，他们根本就不是在命令行中，它产生：

C:\Users\Ken\Desktop\Drawbox\Python36 backup>py setup.py build 
running build 
running build_ext 
building 'drawbox' extension 
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe /c/
nologo /Ox /W3 /GL /DNDEBUG /MD -IC:\Python36\include -IC:\Python36\include "-IC

/EHsc /TpPyDrawbox.cpp /Fobuild\temp.win-amd64-3.6\Release\PyDrawbox.obj 
PyDrawbox.cpp 
PyDrawbox.cpp(2): fatal error C1083: Cannot open include file: 'Drawbox.h': No s 
uch file or directory 

包含文件是有就好了：

C:\Users\Ken\Desktop\Drawbox\Python36 backup>dir "..\Drawbox Library" 
Directory of C:\Users\Ken\Desktop\Drawbox\Drawbox Library 

07/21/2014 07:11 PM <DIR>   . 
07/21/2014 07:11 PM <DIR>   .. 
07/26/2001 08:45 AM    1,407 Color.cpp 
05/19/2005 08:00 AM    5,129 Color.h 
06/29/2002 11:33 AM   117,028 Drawbox.68K.Lib 
01/23/2008 03:33 AM   29,915 Drawbox.h 
. . . 

任何想法，为什么我的include目录被忽略了？使用这些目录的相对路径有没有问题？

如果有人想要看的更深一些，在这里与DISTUTILS_DEBUG输出开启：

Answer 1

您可能需要通过你的include_dirs到setup方法，而不是Extension。至少在我的测试中，这样，相对路径在cl.exe的命令行中正确显示。

另外，一定要使用小[R在你的路径前是否含有反斜线=>r"..\path\to\includes"

---

这是一个用Cython模块我做了，与您的特定include_dir增加了测试：

import sys 
from distutils.core import setup 
from Cython.Build import cythonize 
import numpy as np 

extension = cythonize("unpack.pyx", build_dir="build")[0] 
extension.extra_link_args.append("/OUT:unpack.pyd") # VCPP specific! 

setup(
    name = 'unpack', 
    include_dirs = [np.get_include(), "..\Drawbox Library"], 
    ext_modules = [extension], 
    script_args = ["build_ext", "--inplace"],  
) 

这导致"-I..\Drawbox Tools"出现在命令行CL.EXE，通过的distutils打印。
