  • Error in installing Open-CV with ffmpeg

    24 décembre 2013, par Matteo

    I am trying to install the library Open-CV working on on Ubuntu 11.04.

    I followed all instructions found in the InstallationGuide.

    However after installing with success I realized that I hadn't FFMPEG support because in my configuration file FFMPEG was disabled :

    Video I/O:
    --     DC1394 1.x:                 NO
    --     DC1394 2.x:                 YES
    --     FFMPEG:                     NO
    --       codec:                    YES
    --       format:                   YES
    --       util:                     YES
    --       swscale:                  NO
    --       gentoo-style:             YES
    --     GStreamer:                  YES
    --     UniCap:                     NO
    --     PvAPI:                      NO
    --     V4L/V4L2:                   Using libv4l
    --     Xine:                       NO

    So I tried to rebuild everything after installing FFMEPG as decribed here.

    After configuring installation with the instruction

    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ../OpenCV-2.3.1

    I ran the make command getting this error :

    make[2]: *** [bin/opencv_test_calib3d] Error 1
    make[1]: *** [modules/calib3d/CMakeFiles/opencv_test_calib3d.dir/all] Error 2
    make: *** [all] Error 2

    This is the point of compilation where the error is coming out :
