QTCreator 5.4.1 startup Segmentation Fault


  • Hi,
    I'm new.
    I have a problem with XUbuntu and QtCreator.
    when I try to startup qtCreator by script qtcreator.sh in Qt5.4.1/Tools/QtCreator/bin/ I receive this message:

  • Hi, just guessing but you try starting Qt Creator without the Welcome plugin, type this in Terminal:
    ./qtcreator.sh -noload Welcome

  • @hskoglund said:

    ./qtcreator.sh -noload Welcome

    thanks for reply.
    but It doesn't resolve the problem

  • Ok, maybe time for some diagnostics to see where the problem is:
    strace ./qtcreator.sh

  • @hskoglund said:

    strace ./qtcreator.sh

    I can't add the strace dump, it's out of max lenght

    Interesting is usually what is at the end where the application crashes.

  • Hi just guessing (again!) but when googling, some people recommend typing this in Terminal:
    sudo apt-get install libx11-xcb1

  • @hskoglund said:

    sudo apt-get install libx11-xcb1

    Ok
    I try it but nothing.
    for a moment qtCreator started but after crash and the problem come back.

  • Hmmm, maybe try upgrading to Qt 5.5.1.
