Hi i'm trying to work on a code that use the extra modules of opencv. I've installed the extra modules following the readme txt

$ cd < opencv_build_directory > $ cmake -DOPENCV_EXTRA_MODULES_PATH=< opencv_contrib >/modules < opencv_source_directory > $ make -j5

it works but when i try to compile the code it says that error: ‘xfeatures2d’ is not a namespace-name (in the code there is using namespace cv::xfeatures2d; )

thanks

i've just tried surf_matcher.cpp

opencv2/xfeatures2d.hpp: file or directory not exist #include "opencv2/xfeatures2d.hpp" ^ compilation terminated.

it works fine on these samples but if i try this http://docs.opencv.org/3.0-beta/doc/t... it produces a lot of errors
