C++中用SFML进行Python扩展的错误

Question

<>我不知道C++

并尝试在python中进行扩展，以检查是否在 C++代码和Python中的使用将工作

你知道吗设置.py你知道吗

from distutils.core import setup, Extension
setup(name='init',
      version='1.0',
      ext_modules=[Extension('testemeu',['main.cpp'],include_dirs=[r"C:\Users\v\Documents\code\C\sml\SFML-2.4.2\include"],library_dirs = [r"C:\Users\v\Documents\code\C\sml\SFML-2.4.2\lib"])])

但出现以下错误：

如何解决这个问题？你知道吗

似乎您忘记了在命令中链接到某些库。 我找到了一些你可以链接到的图书馆。将其添加到编译器命令中，并用自己的安装路径交换<sfml-install-path>

-L<sfml-install-path>/lib -lsfml-graphics -lsfml-window -lsfml-system
