helo, please be so kind and replace the useless screenshot with a TEXT version, thank you.

also: os ? compiler ? opencv version ?

cmake version : 3.16.0-rc2
opencv version : opencv 4.1.2
opencv-contrib version : https://github.com/opencv/opencv_contrib

sorry for my bad language

again, please replace the screenshot, and i'll help you.

I have the same issue right now. I tried to build from 4.1.1 from source as well with the xfeatures2d module included. Visual Studio produces the following error:

Severity Code Description Project File Line Suppression State Error C1083 Cannot open include file: 'opencv2/core/utils/tls.hpp': No such file or directory opencv_world

I cannot find the file tls.hpp anywhere in the source code. In 4.1.1 sift.cpp there is an include line:

include <opencv2 core="" utils="" tls.hpp="">

I noticed this line was not in version 3.4.8.

I've met the same problem. on Ubuntu18.04,opencv4.1.2,with CUDA10.1 /home/zhiyu/softWares/OpenCV/opencv-4.1.2/opencv_contrib/modules/xfeatures2d/src/sift.cpp:110:10: fatal error: opencv2/core/utils/tls.hpp: 没有那个文件或目录 #include <opencv2\ core\="" utils\="" tls.hpp=""> ^~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/build.make:482: recipe for target 'modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/src/sift.cpp.o' failed make[2]: * [modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/src/sift.cpp.o] Error 1 CMakeFiles/Makefile2:8044: recipe for target 'modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/all' failed make[1]: [modules/xfeatures2d/CMakeFiles/opencv_xfeatures2d.dir/all] Error 2 make[1]: ** 正在等待未完成的任务..

my cmake command is following: cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_CUDA=ON -D WITH_CUBLAS=ON -D CUDA_FAST_MATH=ON -D WITH_CUFFT=ON -D WITH_NVCUVID=ON -D ENABLE_FAST_MATH=1 -D CUDA_FAST_MATH=1 -D BUILD_opencv_cudacodec=ON -D WITH_V4L=ON -D WITH_LIBV4L=ON -D WITH_OPENGL=ON -D WITH_FFMPEG=ON -D WITH_TBB=ON -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules -D WITH_QT=ON -D BUILD_opencv_python3=ON -D BUILD_opencv_python2=OFF -D BUILD_opencv_cudacodec=OFF -D ENABLE_PRECOMPILED_HEADERS=OFF -D WITH_GTK_2_X=ON -D WITH_IPP=ON -D WITH_JPEG=ON -D WITH_PNG=ON ..

you need EXACTLY the same opencv / opencv_contrib version

your opencv_contrib is from master, the main opencv from 4.1.2 branch.

thanks very much

if you build with opencv_contrib modules, please disable the BUILD_opencv_world option (and build "single module" libs instead.
