I need the "xfeatured" module for my project and I don't know how to fix this problem . I just copy the errors shown in my console maybe you can help me to get out of it :


CMake Error: Could not open file for write in copy operation /home/asma/opencv/opencv-3.0.0-alpha/CMakeFiles/CMakeTmp/CheckIncludeFile.c.tmp CMake Error: : System Error: Permission denied CMake Error at /usr/share/cmake-2.8/Modules/CheckIncludeFile.cmake:40 (configure_file): configure_file Problem configuring file Call Stack (most recent call first): cmake/OpenCVFindLibsVideo.cmake:158 (CHECK_INCLUDE_FILE) CMakeLists.txt:448 (include)

many other errors like the previous one , it tries to open some .h but it fails to o it .

Finally , it's written that : CMake Warning at CMakeLists.txt:1091 (message): The source directory is the same as binary directory. "make clean" may damage the source tree -- Configuring incomplete, errors occurred! See also "/home/asma/opencv/opencv-3.0.0-alpha/CMakeFiles/CMakeOutput.log".
