    Here are my screen shot of the CodeBlock linker setting.

    ffmpeg_build/lib/libvpx.a
    
ffmpeg_build/lib/libswscale.a
    
ffmpeg_build/lib/libwresample.a
    
ffmpeg_build/lib/libpostproc.a

ffmpeg_build/lib/libvformat.a
    
ffmpeg_build/lib/libavfilter.a
    
ffmpeg_build/lib/libavdevice.a
    
ffmpeg_build/lib/libavcodec.a

    Totally 10 libs.

    My Questions :

    1. Are these errors caused by lacking libs or libs not linked.
    2. What libs I missing or what libs should I add to linker.

  • Error while building ParaView on ubuntu

    21 février 2014, par user3337492

    I´ve got school project that I have to build ParaView and work with it in parallel.

    I am using this guide : http://paraview.org/Wiki/ParaView:Build_And_Install

    I´ve installed all the required packages and now it is time to "Configure ParaView With CMake".

    When I do this recomended code

    mkdir $HOME/projects/ParaView-bin

    cd $HOME/projects/ParaView-bin

    ccmake $HOME/projects/ParaView3

    the terminal shows this :

    CMake Error : The source "/home/kulis/projects/ParaView3/CMakeLists.txt" does
    not match the source "/home/kulis/projects/ParaView/CMakeLists.txt" used to
    generate cache. Re-run cmake with a different source directory.

    so instead of ParaView3 I use ParaView in code : ccmake $HOME/projects/ParaView

    then its possible to set all the variables and compile. But there comes the real problem. When i want to compile it, the terminal shows this error message :

    ERROR ADD_PARAVIEW_VIEW_MODULE called without VIEW_TYPE or VIEW_XML_GROUP

    CMake Error : The following variables are used in this project, but they are set to NOTFOUND.
    Please set them or make sure they are set and tested correctly in the CMake files :
    /home/kulis/projects/ParaView/VTK/IO/FFMPEG/FFMPEG_INCLUDE_DIR
    used as include directory in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_avcodec_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_avformat_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_avutil_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG
    FFMPEG_swscale_LIBRARY (ADVANCED)
    linked by target "vtkIOFFMPEG" in directory /home/kulis/projects/ParaView/VTK/IO/FFMPEG

    And I do not really know what to do with it.

    I would very much appreciate your help. Thanks
