Qt Installation

  • I need help. I just reinstalled fedora and I wanted to install Qt so I installed these packages first:

    • sudo yum groupinstall "C Development Tools and Libraries"

    • sudo yum install mesa-libGL-devel

    and then I installed Qt 5.5.1 now I get this error every time I open Qt:

    The fallowing plugins have error and cannot be loaded:
    /home/shahriar/Qt5.5.1/Tools/QtCreator/lib/qtcreator/plugins/libHelp.so: Cannot load library /home/shahriar/Qt5.5.1/Tools/QtCreator/lib/qtcreator/plugins/libHelp.so: (libgstapp-0.10.so.0: cannot open shared object file: No such file or directory)

    but I checked and libHelp.so was there. and it can't build projects(it can't execute qmake)
    I'm guessing that I need to install something else.
    What should I do?

    Hi and welcome to devnet,

    Looks like you are missing gstreamer's 0.10 plugin base

  • Hi. I did what you said and it worked!
    thank you very much
