Question

我有一个C ++包，我之前在Python扩展中构建了它。现在我想在distutils下正确组织它。（在Windows 7上使用Python 3.6.2（一个全新的安装）。）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])

但是，当我实际尝试构建时，它似乎忽略了我的include目录，它们根本就不在它生成的命令行中：

C:\Users\Ken\Desktop\Drawbox\Python36 backup>py setup.py build
running build
running build_ext
building 'drawbox' extension

PyDrawbox.cpp
PyDrawbox.cpp(2): fatal error C1083: Cannot open include file: 'Drawbox.h': No s
uch file or directory

包含文件就可以了：

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
. . .

为什么我的include目录被忽略了？使用这些目录的相对路径是否存在问题？

如果有人想要深入了解，这里是打开DISTUTILS_DEBUG的输出：

您可能需要将include_dirs传递给setup方法，而不是Extension。至少在我的测试中，这种方式相对路径在cl.exe的命令行中正确显示。

此外，如果它们包含反斜杠=＆gt;，请确保在路径前使用 r 。 r"..\path\to\includes"

这来自我制作的cython模块，添加了特定的include_dir用于测试：

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cl.exe的命令行中，由distutils打印。

distutils include_dirs有相对路径？
