Building "Tracking" module in OpenCV extra modules with Cmake does not generate relevant headers of that module

I am not able to get a working custom build for implementation of some OpenCV sample motion tracking examples which requires the module "tracking" part of opencv_contrib. I tried to custom build on on VC12.0 x64 on windows. But it does not generate headers like tracking.hpp and tracker.hpp specific to tracking inside its own folder (C:\OpenCV\build\install\include\opencv2\tracking) like in the case of all other extra modules.

I followed the building procedure as here

My ultimate aim is to run the sample: tutorial_introduction_to_tracker.cpp found here.

Any assistance would be appreciated.

I don't know why there is a problem but you can try to copy opencv_contrib\modules\tracking\include\opencv2.

Try to build only opencv_tracking in VS 2012 to check if there is an error

Can you build opencv_tracking using visual studio solution?

Actually CMake does not build it.

I think there is a problem other module check if modules in CMakeLists.txt are present

try to enable the opencv_datasets module

(afaik, it's only needed for one of the samples, so it should be rather OPTIONAL, imho)

It does not work if I include datasets module.

Something is wrong in your install. You should delete everything (if it is possible) 0 cd \lib 1 git clone https://github.com/opencv/opencv.git

2 git clone https://github.com/opencv/opencv_cont...

3 run cmakegui:

where is source file = \lib\opencv

where to build \lib\opencv\build

4 press configure

5 give OPENCV_EXTRA_MODULES_PATH = \lib\opencv_contrib\modules

6 press generate

@LBerger Thanks for your help. But still unsuccessful. Here is the entire Cmake config file. here

My configuration : General configuration for OpenCV 3.1.0-dev ===================================== If you clone repo you should have dev

Version control: unknown

Extra modules:

***Location (extra):            F:/lib/opencv_contrib/modules*** why haven't got you that?

Version control (extra):     unknown

I have the same issue and finally solved by reinstalling again and again until this link: link text I guess my Ubuntu 18 lacked some dependencies and the instruction above fixed for me. then after the $cmake ........ I got:

-- General configuration for OpenCV 4.1.0 =====================================

-- Version control: 4.1.0

-- Extra modules: -- Location (extra): /home/parallels/opencv_build/opencv_contrib/modules -- Version control (extra): 4.1.1-49-gdda33bf3

. . .

-- OpenCV modules: -- To be built: aruco bgsegm bioinspired calib3d ccalib core cvv datasets dnn dnn_objdetect dnn_superres dpm face features2d flann freetype fuzzy gapi hdf hfs highgui img_hash imgcodecs imgproc line_descriptor ml objdetect optflow phase_unwrapping photo plot python2 python3 quality reg rgbd saliency sfm shape stereo stitching structured_light superres surface_matching text tracking ts video videoio videostab viz xfeatures2d ximgproc xobjdetect xphoto

added extra more module but "tracking" is there! Then after build and install, in “/usr/local/lib”, I see

libopencv_tracking.so ->libopencv_tracking.so.4.1 libopencv_tracking.so.4.1 ->libopencv_tracking.so.4.1.0 libopencv_tracking.so.4.1.0

The error on the code for opencv2/tracking.hpp is gone!
