opencv_world: Unable to compile opencv 3.1 with nonfree xfeatures2d module #7438
Description
I'm unable to compile Opencv with xFeatures2D contrib module without CUDA support.
Running the following cmake comand:
cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules -DWITH_EIGEN=ON -DWITH_FFMPEG=ON -DWITH_JASPER=ON -DWITH_JPEG=ON -DWITH_PNG=ON -DWITH_V4L=ON -DWITH_LIBV4L=ON -DWITH_XINE=ON -DBUILD_PACKAGE=ON -DBUILD_OPENCV_PYTHON3=ON -DPYTHON2_NUMPY_INCLUDE_DIRS=/usr/lib/python2.7/dist-packages/numpy/core/include -DPYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/python3/dist-packages/numpy/core/include -DINSTALL_CREATE_DISTRIB=ON -DWITH_CUDA=OFF ..
Gives that:
-- OpenCV modules:

When compiling the result are this:
In file included from /home/user/deps/opencv/modules/stitching/include/opencv2/stitching.hpp:49:0,
from /home/user/deps/opencv/modules/stitching/src/precomp.hpp:59,
from /home/user/deps/opencv/modules/stitching/src/matchers.cpp:43:
/home/user/deps/opencv/modules/stitching/include/opencv2/stitching/detail/matchers.hpp:52:42: fatal error: opencv2/xfeatures2d/cuda.hpp: No such file or directory
Ok, after removing the stitching module (do i really need to???)...
cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules -DWITH_EIGEN=ON -DWITH_FFMPEG=ON -DWITH_JASPER=ON -DWITH_JPEG=ON -DWITH_PNG=ON -DWITH_V4L=ON -DWITH_LIBV4L=ON -DWITH_XINE=ON -DBUILD_PACKAGE=ON -DBUILD_OPENCV_PYTHON3=ON -DPYTHON2_NUMPY_INCLUDE_DIRS=/usr/lib/python2.7/dist-packages/numpy/core/include -DPYTHON3_NUMPY_INCLUDE_DIRS=/usr/lib/python3/dist-packages/numpy/core/include -DINSTALL_CREATE_DISTRIB=ON -DWITH_CUDA=OFF -DBUILD_opencv_stitching=OFF ..
Gives me this error:
/home/user/deps/opencv/modules/world/src/precomp.hpp:57:43: fatal error: opencv2/xfeatures2d/nonfree.hpp: No such file or directory
Which IS present as seems below:
user@pc:~/deps/opencv/release$ ls ../../opencv_contrib/modules/xfeatures2d/include/opencv2/
xfeatures2d xfeatures2d.hpp
So, what should i do next? And why do stitching modules crashes even with CUDA explicity disabled? :)
