Windows 10上的anaconda cythonize C ++

Question

I have c++ code that compiles fine in MSVS 2015 which is installed on my PC. I've been tasked to make a python extension using cython to be able to call c++ function from our python application. I have installed anaconda 5.2 w/ cython installed already. The c++ has a bunch of header files that need to be included when compiling. I'm trying to build one function and am running into the same error.

My test.pyx looks like this for the one function:

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

The test.pxd is as follows:

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

setup.py is:

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])
)

The test.c is created but then I get a bunch of build errors on the headers in the C++ include folder:

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

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

I'm guessing my setup.py is not correct? Anyone have any pointers on what is happening?

Update to my original post, by adding #include windows.h, the original 'HANDLE' error is now gone but I received this link error now:

Any suggestions on resolving this error? Thank you.

Answer 1

Based on compiler output, HANDLE is not defined. Did you know, that with VS2015 you need to add path to SDK ? It is not included, as I can see. Add C:\\Program Files (x86)\\Windows Kits\\10 \\ include\\ platformtoolset\\um to path. Platformtoolset will define subfolder in yours include path. Hope it helps.

Answer 2

By adding #include windows.h to my header and then changing my original setup.py to the following:

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])

I was able to successfully cythonize one of the functions in my c project. Thank you to all who gave me suggestions that pointed me in the right direction.
