I have recently switched to a windows OS but file is not being found with cython. The file seems correct.
I run:
CD C:\Users\Django\example-of-cython-pyinstaller-and-subzero\1 ACTUAL PROJECT
`python setup.py build_ext --inplace` and get `No such file or directory`
I get:

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.
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.
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.
I have some problems with python . I'm trying to install python using pip :

How can I fix this? Tks for your help !
You can download wrapper and install it, also this package. But you should have tesseract-ocr installed on your PC

I'm trying to compile a hello world example with Cython on Windows 10.
I have visual studio 2015 community.
Python 3.5.2
My setup.py looks like this:
from distutils.core import setup
from Cython.Build import cythonize
setup (
name='print hello world',
ext_modules=cythonize("print_h_w.pyx", compiler_directives=
{'language_level': 3}),
)
The file I'm trying to compile looks like this:
print('Hello World')
I build with this command:
python setup.py build_ext --inplace
I keep getting this error:

I've been doing a lot of research but I've turned up a lot of nothing. How can I fix this?
I think you should have import cython in your print_h_w.pyx file :
import cython
print("hello world")
