Tracking.hpp library not found

edit

Thank you.I have downloaded opencv_contrib-3.4.1 and started rebuilding by adding cmake -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules .. This has completed successfully. After that i ran the command make -j5. it started building libraries and at 16% of completion, an error occurred. How could i solve this error. Please have a look at this..

[ 16%] Building CXX object modules/stitching/CMakeFiles/opencv_stitching_pch_dephelp.dir/opencv_stitching_pch_dephelp.cxx.o /home/hemashre/OPENCV/opencv-3.4.1/modules/stitching/include/opencv2/stitching/detail/matchers.hpp:52:42: fatal error: opencv2/xfeatures2d/cuda.hpp: No such file or directory # include "opencv2/xfeatures2d/cuda.hpp" ^ compilation terminated. make[2]: * [modules/stitching/CM

try to:

• clean the build folder
• disable precompiled headers (cmake -DENABLE_PRECOMPILED_HEADERS=OFF)

I started rebuilding the directory again. I got an error after completing 81%. And the error is /home/hemashre/OPENCV/opencv_contrib-3.4.1/modules/xfeatures2d/src/boostdesc.cpp:653:37: fatal error: boostdesc_bgm.i: No such file or directory #include "boostdesc_bgm.i" ^ compilation terminated. make[2]: * [modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/src/boostdesc.cpp.o] Error 1 make[1]: [modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/all] Error 2 make: ** [all] Error 2

@berak My main motive is to have tracking module. That was build alraedy but the compilation during make was stop due to fatal error: boostdesc_bgm.i: No such file or directory #include "boostdesc_bgm.i". But this is not my concern. How could i avoid this error and proceed to run the applications of tracking.hpp Please have a look into this

boostdesc_bgm.i

needed for the xfeatures2d module (only.) cmake tried to download some (~12) pretrained descriptor models from the net, but failed (e.g your curl could not talk https)

again, the tracking module does not depend on it (as of now).

either fix cmake/curl, or load the missing files manually, or disable the xfeatures2d module: cmake -DBUILD_opencv_xfeaures2d=OFF

@berak Thank you. It worked and i could able to compile the tracking codes. A executable file has created. But while executing it. there is an error. ./tracking: error while loading shared libraries: libopencv_tracking.so.3.4: cannot open shared object file: No such file or directory Please look into this issue.
