    Try to start it on command line with:
    ./qtcreator.sh -noload Welcome
    If it works then disable the Welcome plug-in under "Help/About Plugins..".

  • thanks. it works but the design is different.
    root@ubuntu:/home/hgh1/Qt5.4.1/Tools/QtCreator/bin# ./qtcreator.sh -noload Welcome
    Cannot start '/usr/lib/i386-linux-gnu/qt4/bin/qmake': No such file or directory
    Warning: No kit '{37568147-209f-45aa-8a73-4f89ed9c468d}' found. Continuing.

    I have another compiler for arm. when I opened Qt with your way, that compiler not load.

    Why are you running Qt Creator as root ?

  • @SGaist : As you said I write these code :
    hgh1@ubuntu:~$ cd /home/hgh1/Qt5.4.1/Tools/QtCreator/bin
    hgh1@ubuntu:~/Qt5.4.1/Tools/QtCreator/bin$ ./qtcreator.sh -noload Welcome
    No tool chain set from kit "Desktop".
    No tool chain set from kit "Desktop".
    and Qt not load. just show a black display ( when not root)
    How Can I fix my Qt?

    You did not install Qt. You only installed QtCreator.
    You have to install Qt itself. It looks like you used the online installer, then call /home/hgh1/Qt5.4.1/MaintenanceTool (not as root!), select "Add or remove components" and select Qt 5.5 ("Desktop gcc 64-bit" if you have a 64bit Ubuntu).

    Design is different because you are logged on as normal user but start QtCreator as root.

    And please write QtCreator if you mean the QtCreator IDE and not Qt. Qt is a C++ framework.

  • Sorry. yes I mean Qt creator IDE 5 for 32 bit Ubuntu system , And also I said I installed Qt4.8.3 and attache that qmake to Qt IDE. Since yesterday it was damaged. Before that I worked with my IDE as well.
    My IDE is running on VM ware on my PC.
