Please full error message with line number and file name.

Can check this build\opencv\opencv2\opencv_modules.hpp? You should find #define HAVE_OPENCV_XFEATURES2D

You should have file opencv_contrib\modules\xfeatures2d\misc\python\pyopencv_xfeatures2d.hpp too can you check it?

If you don't need python binding you can try disable it in cmake-gui

are you sure, that your opencv main repo has exactly the same version as your contrib one ?

it seems, you try to compile the master branch from opencv_contrib with 3.4.5 from opencv main, this won't work.

please either update your main opencv to master, or downgrade the contrib one to 3.4.5, too.

Thank you very much! I can compile by you help. I downgraded opencv_contrib to 3.4.5.(changed github branch from master to 3.4) Now I can run opencv-python but pylint works wrong. It doesn't recognize members of cv2, so I add an argument "extension-pkg-whitelist=cv2" to setting.
