Unresolved External Symbol error OpenCV Cuda

asked 2019-07-15 06:54:07 -0500

Hello to everyone, I want to build an application using C++ OpenCV Cuda library. I have installed OpenCV 3.1.1 and Cuda 10.1. I am using Windows 10 and Microsoft Visual Studio 2019. I have tried the below-linked example. Such as there is no opencv2/gpu/gpu.hpp. Then I have found a solution, it was changed when the version update above 3. But my problem still consists. There is no opencv2/cudaarithm.hpp file or other cuda files. I have downloaded these files from GitHub. But it does not solve my problem again. This time I have faced up. Could you help me how can I solve it? I need to solve it as soon as possible.

Example: https://opencv.org/cuda/ Found solution: https://stackoverflow.com/questions/1...

cv::debug_build_guard::_InputArray -- you have a DEBUG project, but try to link RELEASE opencv libs

I tried with Release but it is still same. BTW, I have linked for release opencv_world331.lib and for debug opencv_world331d.lib .
