OpenCV source make error: OpenCV/modules/features2d/src/matchers.cpp:47:23: fatal error: Eigen/Array: No such file or directory
Hi, Am using OpenCV3.1,Python2.7. At sudo make of opencv source cloned from git rep, below log excerpt: (Kindly guide. Thanks in advance).

Just before this error, I was getting error for Eigen/Eigenvalues no such file or dir... which was resolved by installing libeigen3-dev. Now, this new error is coming. I checked usr/include/eigen3/ but Array doesnt exist, it seems Array is deprecated in OpenCV3 ? So, how do i go ahead?
it did not fid the eigen lib (or the wrong one).
can you try to add
-DWITH_EIGEN=OFFto yourcmakecmdline ?Hi Berak, The mentioned error is'nt coming with WITH_EIGEN=OFF but getting below error:
OpenCV/build/make_dir/CMakeFiles/CMakeTmp/CheckIncludeFile.c:1:25: fatal error: sys/videoio.h: No such file or directory. compilation terminated.
