    Are you calling configure from the top folder ?
    If so, did you clean everything before calling configure again ?

    As I suggest every time: use out of source builds, that way if something goes wrong or you want to use a different set of option, you can simply nuke everything or change the folder and you know for sure you start from a clean state.

    @SGaist i called configure from the top folder i got from the .tar.gz file. I just deleted config.cache before calling configure again. How would i go about cleaning everything before calling configure again? What are out of source builds?

      make distclean or make confclean

      As the name suggests: builds that happens out of the source tree.

      Basically:

      mkdir /home/your_user/build_qt5
      pushd /home/your_user/build_qt5
      /path/to/Qt_sources/configure -nomake tests -nomake examples
      make -j (number_of_cores * 2 + 1)
      make install
      popd

        @SGaist Ok, is this even useful now? I mean i already installed Qt5 so isnt it a little bit too late?
        Btw in my other post about my code are some new outputs since i installed Qt5.

          It will be in the future when you'll build Qt again.
