  • Configuration spécifique d’Apache

    4 février 2011, par

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • 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 :

    can anybody please tell me what's the problem with installation process I'm following ?

    Why is there this library referentiation error ?
