使用cython | LINK生成错误：致命错误LNK181

Question

我正在使用anaconda3shell来执行cython脚本，以便以后可以使用Python调用我的函数。我有出版商的源代码，是用C/C++编写的，没有任何C/C++编程经验

因此，我想使用cython来包装C/C++文件。我正在使用Windows 10和基于x64的操作系统、Visual studio 2017和anaconda3来执行我的所有python模块

我的setup.py文件如下所示：

#setup.py
from setuptools import setup,Extension
from Cython.Build import cythonize

extensions=[Extension("IrisAO_Python", [".\\DM files\\IrisAO_Python.pyx"],
                      include_dirs = [".\\DM files\\"],
                      library_dirs = [".\\DM files\\"],
                       libraries=["IrisAO.Devices"])]

setup(
    name = "irisao",
    ext_modules = cythonize(extensions),
    packages = ['DM files'],
    package_dir ={'DM files':'.\\DM files'},
    py_modules=['__init__','IrisAO_Python_MirrorControl'] 
)

我敦促研究此问题的专家从我的github存储库下载所有文件。如果不下载文件，对问题的调试将毫无用处https://github.com/abani-nayak/IrisAO-for-Windows/tree/editing

接下来，我使用anaconda3 shell编译扩展setup.py：

(base) C:\Users\Abani\Documents\DM setup\Final>python setup.py build_ext --inplace

然而，我得到一个致命的链接错误LNK181。错误预览可在此处找到：

错误显示：无法打开输入文件“Files.obj”。我不知道为什么它会说无法打开输入文件，尽管我的“DM Files”文件夹中没有这样的文件“Files.obj”

因此，我请求专家提供必要的帮助。同样，执行cython脚本所需的所有文件都可以在这里找到：https://github.com/abani-nayak/IrisAO-for-Windows/tree/editing

Answer 1

我已经找到了问题的答案。我做了一些尝试错误，但我不知道为什么它应该这样工作。不过，我们欢迎对这个问题提出有价值的建议以及专家们的回答。因此，我做了以下工作：

我将setup.py文件移到了“DM files”文件夹中，该文件夹包含所有c/c++文件。接下来，我修改了setup.py文件，如下所示：

#setup.py
from setuptools import setup,Extension
from Cython.Build import cythonize

extensions=[Extension("IrisAO_Python", ["IrisAO_Python.pyx"],
                      include_dirs = ["."],
                      library_dirs = ["."],
                       libraries=["IrisAO.Devices"])]

setup(
    name = "irisao",
    ext_modules = cythonize(extensions),
    packages = ['DM_files'],
    package_dir ={'DM_files':'.'},
    py_modules=['__init__','IrisAO_Python_MirrorControl'] 
)

我在anaconda3中运行了执行setup.py的常用命令：“python setup.py build\u ext inplace”

命令执行时没有任何错误。以下是预览：
