找不到程序.dll文件

Question

我尝试遵循https://docs.opencv.org/3.1.0/d4/d18/tutorial_sfm_scene_reconstruction.html此代码，但无法构建。我使用opencv和额外贡献版本3.4.5

我试图将.dll添加到项目中，但是它不起作用。

和此.exe错误

Answer 1

这是Windows API框架的常见模式。您安装/构建一些框架，该框架附带了一组INCLUDE，LIB和DLL文件。您的代码包括标头和DLL的存根lib文件的链接，以便进行编译。但是在运行时，找不到依赖的DLL，因为它们不在您的PATH中（或与EXE相同的文件夹中）。

对话框从字面上告诉您错误。将ceres-debug.dll复制到与EXE相同的文件夹中。或者最好如上所述，只要确保PATH环境变量中包含ceres-debug.dll的任何文件夹即可。通过更新PATH，您可能会解决程序或ceres-debug.dll所依赖的其他DLL的许多后续错误。

有道理吗？
