opencv - 制作失败 98% Linking CXX shared module ..\..\lib\cv2.pyd

问题描述

我尝试使用 mingw 0.6.2 在代码块（Windows 7）中构建 opencv 3.4.0，但在 98% 时我有五个与 python 相关的错误，我不知道为什么。

这是代码块中的构建日志：

并获得 buid 消息：

||=== Build: all in OpenCV (compiler: GNU GCC Compiler) ===|

解决这个问题的任何帮助将不胜感激:)

解决方案

如果有人服务，对我来说，解决方案是在 cmake 中禁用 BUILD_opencv_python
