Python ImportError：DLL加载失败：无法优化另一台计算机生成的DLL

Question

总之，计算机A不能引用计算机A生成的DLL。

1. 使用SWIG软件包获取HKIPCamera_wrap.cxx： （源文件包括HKIPcamera.cpp，HKIPcamera.h和HKIPcamera.i） Swig -I“ D：\ Program Files \ opencv3 \ opencv \ build \ include” -python -c ++ HKIPCamera.i
2. 创建一个DLL项目，将HKIPcamera.h文件添加到头文件，然后将HKIPcamera_wrap.cxx，HKIPcamera.cpp添加到源文件。
3. 将生成的.dll文件重命名为_HKIPcamera.pyd并将其放置在HKIPcamera.py的同一目录中，我认为可以在Python中引用该文件。
4. 生成.dll的计算机A可以正常引用该模块，然后将该.dll移至计算机B。
5. 通过“ dependecy walker”查询依赖的DLL来加入，但仍然无法工作...

很好...看来我忘记了一个目录。
