Windows 10上的anaconda cythonize C ++

Question

我的C ++代码可以在PC上安装的MSVS 2015中很好地进行编译。 我的任务是使用cython进行python扩展，以便能够从我们的python应用程序调用c ++函数。 我已经安装了带有cython的anaconda 5.2。 C ++有很多头文件，在编译时需要包含这些头文件。 我正在尝试构建一个函数，并遇到相同的错误。

我的test.pyx看起来像一个函数：

cimport test
cimport cython
def pxd_PIXCIclose():
    res = test.pxd_PIXCIclose()
    return res

test.pxd如下所示：

cdef extern from "D:\epix\inc\xcliball.h":  
int pxd_PIXCIclose()

setup.py是：

from distutils.core import setup
from distutils.extension import Extension
from Cython.Build import cythonize

ext_modules = Extension(
                name = "test",
                sources=["test.pyx"],
                include_dirs=["D:\epix\lib", "D:\epix\inc"],  
                library_dirs="D:\epix\inc\XCLIBW64.lib","D:\epix\lib\PXIPLW64.lib"]
              )

setup(
  name = "test.pyx",
  ext_modules = cythonize([ext_modules])
)

创建了test.c，但随后在C ++ include文件夹的标头中出现了一系列构建错误：

python setup.py build_ext --inplace --compiler=msvc

Compiling test.pyx because it depends on .\test.pxd.

我猜我的setup.py不正确？ 任何人都对发生的事情有任何指示？

通过添加#include windows.h更新到我的原始帖子，原始的“ HANDLE”错误现在消失了，但是我现在收到此链接错误：

有关解决此错误的任何建议？ 谢谢。

Answer 1

根据编译器输出，未定义HANDLE。 您是否知道，使用VS2015，您需要添加SDK的路径？ 如我所见，它不包括在内。 将C：\\ Program Files（x86）\\ Windows Kits \\ 10 \\ include \\ platformtoolset \\ um添加到路径。 Platformtoolset将在您的包含路径中定义子文件夹。 希望能帮助到你。

通过将#include windows.h添加到标题中，然后将原始的setup.py更改为以下内容：

from distutils.core import setup
from distutils.extension import Extension
from Cython.Build import cythonize


ext_modules = Extension(
          name = "test",
          sources=["test.pyx"],

          include_dirs=["D:\epix\lib", "D:\epix\inc"],
          library_dirs=["D:\epix\inc"],
          libraries=["XCLIBW64", "PXIPLW64"]

          )

setup(
name = "test.pyx",
ext_modules = cythonize([ext_modules])

我能够成功地对c项目中的函数之一进行cythonize处理。 感谢所有为我提供建议的人，这些建议为我指明了正确的方向。
