qtcreator under WSL ubuntu throws an error



  • i ve installed qtcreator using sudo apt install qtcreator

    after installation

    i run qtcreator command, and i have the output:

    qtcreator: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory
    

    what can be the problem?


  • Lifetime Qt Champion

    @iwrwrc How was it installed in WSL?



  • did first

    sudo apt-get install qt5-default
    sudo apt-get install build-essential
    sudo apt-get install libfontconfig1
    sudo apt-get install mesa-common-dev
    sudo apt-get install libglu1-mesa-dev -y
    

    and then

    sudo apt install qtcreator
    

    i didn't make the Set file association with pro files section as mentioned here https://wiki.qt.io/Install_Qt_5_on_Ubuntu tho

    because, i could not found the .local folder...
    .. is there a way to troubleshoot the problem?

    libQt5Core.so.5 shared library is not found.
    You can search manually for it to see whether it is somewhere.



  • yes it's here. ive found it using apt-file

    libqt5core5a: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
    libqt5core5a: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5.12

    @iwrwrc Looks good. Try

    ldd qtcreator
    

    What does it output?



  • @jsulm said in qtcreator under WSL ubuntu throws an error:

    ldd qtcreator

    ldd: ./qtcreator: No such file or directory
    

  • Lifetime Qt Champion

    @iwrwrc Provide whole path to qtcreator

    @iwrwrc Try to create a symbolic link /lib/x86_64-linux-gnu/libQt5Core.so.5 pointing to /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
    For some reason libQt5Core.so.5 is in /usr/lib/x86_64-linux-gnu and other Qt stuff in /lib/x86_64-linux-gnu



  • @iwrwrc said in qtcreator under WSL ubuntu throws an error:

    it starts pointing to itself


  • Lifetime Qt Champion

    Hi,

    How did you create the symbolic link exactly ?



  • i did

    ln -s /lib/x86_64-linux-gnu/libQt5Core.so.5  /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
    

    had an output saying file does not exist. so i forced it using

    ls -sf /lib/x86_64-linux-gnu/libQt5Core.so.5  /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
    

    after this. every time i have a warning of too many levels of symbolic links.

    My problem is now resolved using just this command

    sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
    

  • Lifetime Qt Champion

    @iwrwrc It's (ln -s target link_name):

    ln -s /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 /lib/x86_64-linux-gnu/libQt5Core.so.5
    

    See "man ln".



  • @jsulm said in qtcreator under WSL ubuntu throws an error:

    See "man ln".

    @iwrwrc
    Please take the time to read the manual page on a command if you don't know how to use it or it gives an error you don't understand, rather than just continuing blindly....

    My problem is now resolved using just this command

    sudo strip --remove-section=.note.ABI-tag /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

    Wot?? We don't execute some command to alter a supplied file in a system area because we have some issue...! Restore this file immediately!



  • Yes, thanks.I see that i confused between target and link name



  • Ok, i'll try restore the file. and see if i can resolve the issue



  • @JonB I have resotred it now.

    and

    ls -l /lib/x86_64-linux-gnu/libQt5Core.so.5
    
    lrwxrwxrwx 1 root root 41 Nov 25 11:15 /lib/x86_64-linux-gnu/libQt5Core.so.5 -> /usr/lib/x86_64-linux-gnu/libQt5Core.so.5
