I have a trouble - I want to compile opnecv with opencv_contrib. I use Visual Studio 2013, last version cmake, opencv and opencv_contrib from github but... suddenly I can't.

I did it in past, according to this tutorial: http://docs.opencv.org/3.2.0/de/d25/tutorial_dnn_build.html and everything was fine, but now compilator show more than 100 fatal errors.

First and second errors look this:

error C2440: 'type cast' : cannot convert from '__m128i' to '__m128'    
error C2660: '_mm256_insertf128_ps' : function does not take 2 arguments

The rest are similar to this:

error LNK1181: cannot open input file 'C:\opencv_root\build_opencv\modules\core\opencv_core_AVX2.dir\Release\mathfuncs_core.avx2.obj'

List of my activities:

  • download sorce code from github
  • run cmake, choose source code, choose destination folder, set path to 'extra modules', generatre
  • run OpenCV.sln, choose "release", select ALLBUILD, click "build" (like on screen) screen

I tried x32 and x64 version, tried to compile it with and without opencv_contrib modules, but this still won't work.

Where to find a solution, when I make a mistake? Help, please :)

Regards!

There is an OpenCV 3.2.0 with opencv_contib binary for 64-bit Windows available in github. You can download it from here. It's complied with Visual Studio 2015 and requires .Net Framework 4.5 or above that you can download it separately from Microsoft before installing it.

Hope this would save your time to get the opencv_contrib and make it works.

  • Thanks for you reply! Unfortunately, from opencv_contrib I need only arUCO module, but this compilation as I can see not include it – Fidor Apr 09 '17 at 17:35
  • Have you installed it and checked? For python, type (1) `import numpy as np`, (2) `import cv2` and (3) `help(cv2.aruco)` that tells **ArUco** is there.. For C++, the header files, `charuco.hpp` & `dictionary.hpp`, are in `C:\Program Files\OpenCV 3.2.0\include\opencv2\aruco` directory. – thewaywewere Apr 09 '17 at 18:29
  • In fact i haven't installed it, just looked on surface, looking for aruco folder. Thanks for link, but I did not want to use precompiled libraries I worked hard and I found solution my problem. On CMake I had to changed CPU_BASELINE and CPU_DISPATCH from SSSE3 to SSE2. After this changed everything worked fine – Fidor Apr 23 '17 at 11:59
