    Default QT5.7 problem building examples and more with qtcreator

    Hi all,

    hope someone can please give me a hint here. I am stuck :-(

    I am running Qt5.7 on Ubuntu 14.04 (64bit) in a virtualbox.


    Qt Code: 
    1. which qtcreator 
    2. /usr/bin/qtcreator
    3.  
    4. qtcreator -version
    5.  
    6. Qt Creator 3.0.1 based on Qt 5.2.1
    7. ...
    To copy to clipboard, switch view to plain text mode 

    and my qmake -query gives me

    Qt Code: 
    1. qmake -query
    2. QT_SYSROOT:

    25. QMAKE_VERSION:3.0
    26. QT_VERSION:5.7.0

    now if I open qtcreator and compile one of the many examples (fails with all of the ones I have tried.....and i have tried a lot)

    I get

    Qt Code: 
    1. libGL error: pci id for fd 12: 80ee:beef, driver (null)

    the stuff with openGL I guess are not critical, but the last line is bad..


    I guess/hope that the problem is just a configuration problem inside qtcreator.

    I have configured my kit to use the qmake in the /gcc_64/bin

    the gcc that is being used now is the gcc in /usr/bin/gcc-4.8

    Qt Code: 
    1. /usr/bin/gcc-4.8 --version
    2. gcc-4.8 (Ubuntu 4.8.5-2ubuntu1~14.04.1) 4.8.5

    can anybody advice me here?

    I think the problem might be that your mesa library (which implements OpenGL on linux) might be old. You could try to update or switch to a different OpenGL implementation.

    Please use CODE tags when posting source code so it is more readable. Click "Go Advanced" and then the "#" icon to insert the tags. Paste your code between them.
