  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • Linking error stdc++

    11 mars 2016, par Per M.

    Why am I having these linking errors ?

    Here is a short sample of link errors, there are hundreds similar :

    I am on Debian 7, using Clang compiler. The code is built using a makefile system, the following compiler flags is used

    CXXFLAGS = -g -I /opt/intel/composer_xe_2015.1.133/ipp/include/ -Wno-deprecated -D_GNU_SOURCE  -D_REENTRANT -D__STDC_CONSTANT_MACROS -I/usr/include/postgresql/ -I/usr/local/Qt/5.2.1/gcc_64/include/QtX11Extras/ -I/usr/local/Qt/5.2.1/gcc_64/include/QtWidgets/ -I/usr/local/Qt/5.2.1/gcc_64/include/ -I/usr/local/Qt/5.2.1/gcc_64/include/QtGui/ -fPIC -fPIE -I/home/go/ffmpeg_build/include/ -I/usr/local/Qt/5.2.1/gcc_64/include/QtCore/  -fPIC -fPIE -I/home/go/ffmpeg_build/include/libavcodec -I/home/go/ffmpeg_build/include/libavformat/

    If I add -lstdc++ to my compiler options, FFmpeg gives link errors instead. I have wrapped FFmpeg includes in extern "C" as I have seen elsewhere on this site. It doesn’t help. But I don’t think that is the problem here.

    FFmpeg is compiled as dynamic libs from source. (I had the same behavior when I linked static libs.)

    I have checked the FFmpeg libs with ldd and the dependencies is in place. I have checked for 32/64 mix-ups but it all seems to be 64 as it should be.

    root@antec :/usr/local/lib# file libavcodec.so.57.27.101

    root@antec :/usr/local/lib# file /lib/x86_64-linux-gnu/libc-2.13.so
    /lib/x86_64-linux-gnu/libc-2.13.so : ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), BuildID[sha1]=0xb5053aa2420700afc9687ab357a8d5d89fcb1bd0, for GNU/Linux 2.6.26, stripped

    The example contained in FFmpeg source compiled and linked fine.

    Is there any other external part that could give these errors ? C++11 ? Any indication could help. Thanks.
