Opencv source compile with cuda generates multiple definition link error

Question

I want to build the opencv 3.2 with cuda 8 and I have installed all the required libraries for cuda in my linux system which is a Debian 9 testing (stretch) 4.9.0-1-amd64 after generating makefiles with cmake successfully I get multiple definition linkage error by executing make command. I have tried many configurations with cmake and also I have checked almost all the relating issues in many forums but I couldn't find any solution. In cmake, I have changed cuda compiler to gcc-5 since cuda 8 needs gcc compiler no later than version 5 and the default gcc compiler is version 6.3 Here is my cmake configuration output:

Answer 1

Okay, found a workaround at last. (Btw, I'm using CMake GUI).

You have to uncheck CUDA_SEPARABLE_COMPILATION in the CMake-GUI options.

Unfortunately, this just a workaround and CUDA separable compilation cannot be used in Linux. (You have to use Windows for this). I found this in a issue(https://github.com/opencv/opencv/issues/5557) in the OpenCV repository.

PS:

I am having trouble building OpenCV with Qt5. If you are successful in doing so, please notify me in the comments. Thanks!
