Cannot open Qt5 creator after complete installation on Raspberry Pi 3



  • I have my Raspberry Pi 3 running on standard raspbian GNU/Linux 9 stretch. I wish to install Qt5 creator for source code development.

    here are the commands i used to run the installation:

    sudo apt-get install qt5-default
    
    sudo apt-get install qtcreator
    

    I can find the Qt Creator apps in my desktop tab programming>Qt Creator. I clicked on it but nothing happen.

    I opened my terminal and type qtcreator to run the apps, it shows the message below:

    This application failed to start because it could not find or load the Qt platform plugin "xcb"
    in "".
    Available plaform plugins are: eglfs, linuxfb, minimal, minimaleg1, offscreen, vnc, web1, xcb.
    Reinstallting the application may fix this problem.
    Aborted

    I have retried to uninstall everything and reinstall, same error message show up.

    May i know how to fix the problem above?

    Debian packages are maintained by Debian. It's something they should solve if they support RPi, try raising the issue on some Debian mailing list or bug tracker.

    A standard way of using Qt on RPi is to cross-compile and use Qt Creator on your host machine.

    Judging from error message: try running QtC with different platform plugin, like this:

    qtcreator -platform "eglfs"

    Hi,

    You should also start your application with the QT_DEBUG_PLUGINS environment variable set to 1. That will give you information about what is happening.
