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.

-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.
