    I am writing because I am trying to find the solution to a problem. I need to enable the display of gif and jpg images using 4.8.5 Qt version.
    I found many references to different links and information around the net but none of them led me to the solution. So I ask you to list the steps to follow to solve the problem or to show me the reference to a web page.

    At the time I created the "plugins/imageformats" folder and tried to link the library statically following documentation. At the end of procedure I found this issue: undefined reference to qt_plugin_instance_qjpeg()

    Thx in advance

      Hi and welcome to devnet,

      Did you build Qt statically ? What OS are you running ?

        Hi,
        yes I build Qt with '-static' parameter rather that using '-shared'. Now I'm using Ubuntu 10.04 LTS but in the future I will cross compile for ARM.

          Did you also add to your code/pro file the bits necessary to handle static plugins ?

              git clone setup-patch ?

              There's no other tool to clone Qt's code. You already have webkit in Qt 4 sources.
