QT4.8.4 Where do I find a full SDK install for Windows 7 with MINGW and QT creator ?



  • If this is no longer available, where can I download the separate packages and where is described how to install them separately?
    I habe tried to install the 3 parts separately, but I cannot get them to work.



  • Hi there, I also had lot's of problems with Qt Creator 2.6.1 and the older versions of Qt (4.8.4). You could get the mingw from sourceforge, but that caused me to loose the debugger helpers. (reading a QString becomes terrible diffecult)
    There is good documentation how to install a new toolkit in the new QtCreator, so start reading. You must setup the tool kits and you should be ready to go.

  • Oh, btw, you need to install the CDB debugger from the microsoft development kit!

    welcome to devnet

    AFAIK at the moment there is no official full SDK as you are requesting.

    At the moment there is some sort of a "minimal SDK with Qt5 and Qt creator":http://qt-project.org/forums/viewthread/23152/ available. It does not contain a compiler at the moment.



  • I current use the SDK for QT 4.8.0 which I downloaded in 2012 at Nokia.
    It included all. Unfortunately I didn't store this SDK, but now I need to install this QT4.8.x environment on another computer.
    Als long as QT5 is not working for MINGW in need to work with QT4.8.4

    The fact that this SDK is no longer available makes life very hard for new
    QT users.

    Where can I find links to the right MNGW compiler version etc and where is described how to setup the toolkits and the compiler?
    In which order do I need to install (I tried 1 MINGW, 2 QT LIBS, 3 QT Creator?
    (Like I said, I tried to setup the QT versions, but I could not get any build configuration in QT Creator and could not build).

    The order seems to be ok to me.
    However, I have done an installation in a slightly different sequence.

    • Installed a fresh MinGW 4.7.2
    • Installed Qt creator 2.6.1
    • Compiled Qt 4.8.4 with MinGW 4.7.2 since the MinGW pre-compiled version is not compatible.

    I am not sure, if this might work on a virgin machine not having any Qt related stuff on it. :(

    The current main problems are:

    • Qt SDK is outdated
    • Qt 4 pre-compiles are based on MinGW 4.4 or other compilers
    • AFAIK MinGW 4.4 is not easily downloadable. Moreover it is outdated as well. Moreover, also MinGW is not in an orderly situation at this time.

    Maybe it helps to install Qt5 libs (they include Qt creator) with a recent version of MinGW and do the Qt 4.8.4 lib compilation. This is in my opinion a stupid advice, since you would install Qt5 only for having the qmake stuff available. However, it would probably give you a similar starting as I had when doing a recent install and compilation.

    For the MinGW builds there has been another recent "discussion":http://qt-project.org/forums/viewthread/23519/

    I consider Lukas' advice as good. Unfortunately it came 2 month too late. I have been using MinGW downloaded from original site as indicated in "here":http://qt-project.org/forums/viewthread/23623/#109723

    Beware, I am not considering this as straight forward nor a good advice. Unfortunately the only way I see at this time.



  • Hi, I tried to compile QT4.8.4 with MinGW 4.7.2 but I had no luck, the compilation lasted very long, about 10 hours, I see no errors, but all the QT dll's are not build.
    I am a nwby in this, I never compiled QT before.
    Do you have the right compile instructions for QT4.8.4 with MinGW 4.7.2?

    I also sens a e-mail about this problem to Digia.
    Their answer was ver short, please seek help i de community.
    So I fear the worst for QT if they abandon the open source version.

    Now I am stuck and don't know what to do.
    Or should I switch to wxWidgets?

    Please have a look to "this response from one of the Trolls":http://qt-project.org/forums/viewthread/23001/#111222 That is the most detailed information I have at hand.

    The compilation time of 10 hours seems to be a bit long. However, that is also dependent on the number of options and HW you are using.

    What -platform option did you use (see details "here":http://doc.qt.digia.com/qt/configure-options.html#cross-platform-options )?
    In qt 4.8.4 there were no special MinGW 4.7.2 parameters available so I had chosen mkspecs\win32-g++-4.6 also with MinGW 4.7.2. They did not create a problem for me.

    They might be happier with detailed responses when you are buying a commercial license.
    One thing you have to see is that Digia has taken over the responsibility for Qt from Nokia very recently. The structures have to settle a bit and some fine-tuning is required. The take-over and the release of Qt5 with the birthing pains brought a bit a disorder in things. Hope that this will settle soon.

    That has to be certainly your decision. Since I do not know wxWidgets I cannot give any comment to what the issues might be.

    However, keep the fingers crossed that be end of this or mid of next month latest an update for the SDK is coming out as announced in the referenced links above.
