Distutils在使用WinPython 3.6时不会调用“link.exe”，但是使用WinPython 3.5它会起作用

标签： compilation distutils python-c-extension python-3.6

我最近从Winpython版本3.5升级到python 3.6的相应版本。因此，我必须使用新的解释器重新编译我的C扩展。我的设置脚本如下所示：

from distutils.core import setup, Extension
import numpy.distutils.misc_util

c_ext = Extension("heapoperations", ["heapoperations.c"])

setup(
    ext_modules=[c_ext],
    include_dirs=numpy.distutils.misc_util.get_numpy_include_dirs(),
)

使用python 3.5时的控制台输出是

Found executable C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\amd64\link.exe

但是，当我使用python 3.6运行相同的脚本时，我得到了

running build_ext

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe /c /nologo /Ox /W3 /GL /DNDEBUG /MD -I"C:\Program Files\WinPython-64bit-3.6.0.1Qt5\python-3.6.0.amd64\lib\site-packages\numpy\core\include" -I"C:\Program Files\WinPython-64bit-3.6.0.1Qt5\python-3.6.0.amd64\include" -I"C:\Program Files\WinPython-64bit-3.6.0.1Qt5\python-3.6.0.amd64\include" -I"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\INCLUDE" -I"C:\Program Files (x86)\Windows Kits\10\include\10.0.10240.0\ucrt" -I"C:\Program Files (x86)\Windows Kits\10\include\10.0.10240.0\shared" -I"C:\Program Files (x86)\Windows Kits\10\include\10.0.10240.0\um" -I"C:\Program Files (x86)\Windows Kits\10\include\10.0.10240.0\winrt" /Tcheapoperations.c /Fobuild\temp.win-amd64-3.6\Release\heapoperations.obj
Found executable C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe

即，link.exe未被调用。结果是我没有得到允许我使用代码的.pyd文件。

有什么可以解释这种行为？我怎么能让一切都在WinPython 3.6下运行？

我在Windows 10 64bit下使用64位WinPython。

我试过http://dan.iel.fm/posts/python-c-extensions/ （和来自https://gist.github.com/douglas-larocca/099bf7460d853abb7c17的_chi2.c）

结果：
