Installation freezes in ubuntu 11.40 (x32)



  • I tried to install Qt SDK on a linux machine but the installation hangs my computer.

    According to the instructions, I chmod the file Qt_SDK_Lin32_offline_v1_1_3_en.run and run it under terminal (so that I can see the output). I get the error message appearing several times

    @(Qt_SDK_Lin32_offline_v1_1_3_en.run:3126): Gtk-CRITICAL **: IA__gtk_widget_style_get: assertion `GTK_IS_WIDGET (widget)' failed@

    A window appears welcoming to the setup wizard, click next, select installation folder, and default (or custom) installation. When I click Next, the computer practically hangs, uses the hardrive quite a lot, mouse pointer freezes and occasionally moves and nothing much happens. It is still possible (but very slow) to go to a text console (ctrl+alt+F1) and kill the installation. The same freezing behaviour occurs with the online installer.

    I was wondering if there is a solution or a way around this problem, please.

    I recently noticed that I can install Qt-creator using Ubuntu software centre but it is an older version that does not install mobile devices tools and libraries, neither it gives choice of updates.

    Thanks



  • Start the installer with parameter:
    @-style cleanlooks@
    That should work.



  • That worked. Thanks Yordan.

    perdigao,

    I just follow Yordan opinion,add "-style cleanlooks ", but it still doesn't work, could you give me some guide.

    below is what I got in terminal:

    ./Qt_SDK_Lin32_offline_v1_1_1_en.run -style cleanlooks
    then error still :
    QCoreApplication::applicationFilePath: Please instantiate the QApplication object first
    Unknown option: -style

    thanks!

    It worked for me too on Ubuntu Oneiric 11.10 (32 bit), thanks!



  • -style cleanLooks

    Worked like a charm for me too on Ubuntu 11.10 (32-bit).

    Seems that just the installer is incompatible with the Ubuntu Unity Desktop. Once installed, Qt Creator, Qt Designer, Qt Linguist and the package manager/updater work fine without any additional startup parameters.



  • Try using sudo
    sudo ./Qt_SDK_Lin32_offline_v1_1_1_en.run



  • I confirm that "-style cleanlooks" worked in Ubuntu 12.04 64bit.
