opencv_core241d.dll missing

asked 2012-11-17 11:06:22 -0500

I have set up OpenCV 2.4.3 on Windows 7 following this guide: http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_install/windows_install.html#windows-installation Which has worked fine, all the examples work etc. However when I tried to create a new project in Visual Studio 2010 following this guide: http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html#windows-visual-studio-how-to I get the following run-time error: "The program can't start because opencv_core241d.dll is missing from your computer. Try reinstalling the program to fix this problem." The dlls are in fact there, but I don't know why my program can't find them. I have tried googling the answer, and have tried various things including adding the location to the system path, to no avail. How do I solve this problem?

Hi! In error message needed 2.4.1 version of this lib, and you have 2.4.3 version of OpenCV. May be, you should modify linker paths.

No, I installed the latest version. For now Ive just had to put the necessary dlls in the same folder as my solution.

If you run not in Visual Studio, you should put this necessary .dlls in folder with your .exe. It's a regular case for project with .dlls.

Placing dll's in the project folder is actually the worst approach you could do to my knowledge. It is mostly the case that the actual system configuration is wrong :)

There was actually a problem with the current guide. A bugfix for this has already been applied. Basically the guide tells you to configure the lib and include folder wrongly. To have the correct fix, look at the pull request here.

Does this fix the problem?
