    Hi,
    I am trying to compile some QT examples under linux mint 18 and get the same errors. I am using the nvidia drivers. The QT Creator is from the standard repositories. Since many people seem to suffer from this, there are many solutions on the web. I tried these:

    sudo apt-get install libgl-dev
    sudo apt-get install mesa-common-dev
    sudo apt-get install libglu1-mesa-dev freeglut3-dev mesa-common-dev libgl1-mesa-dev
    sudo apt-get install libxi-dev build-essential libdbus-1-dev libfontconfig1-dev libfreetype6-dev libx11-dev
    apt-get install libqt4-dev zlib1g-dev libqt4-opengl-dev

    and also made symbolic links, all to no avail. When I run: locate libGL I get this output:

    /usr/lib/libGL.so

    along with some steam and playonlinux stuff. My Matlab installation and steam work fine with OpenGL.
    It there anything I can do to resolve this?

    Regards,
    Stephan

    Hi and welcome to devnet,

    What version of Qt did you install on your machine ?

    Hi,
    Thanks for the response. From the standard Mint repositories, I installed this version:

    • Qt Creator 3.5.1

    • Based on Qt 5.5.1 (GCC 5.2.1 20151129, 64 bit)

    I notice that the error I get is slightly different from the one at the top of the topic: fatal error: QtOpenGL: No such file or directory but it appears to be related.

    Regards,
    Stephan

    I meant Qt itself not Qt Creator.

    If you didn't use the Qt installer then you should check the Qt 5 packages that you have installed in Ming. You might be missing some of them.

    ah, sorry. I found this in the software manager:
    Qt5-default: 5.5.1+dfsg-16ubuntu7.2
    Libqt5qml5: 5.5.1-2ubuntu6
    Libqt5quick5: 5.5.1-2ubuntu6

    is this what you meant? Or can I run a command that reveals the correct version?

    regards,
    Stephan

    Then it's Qt 5.5.1.

    I don't know if Mint does any customisation for the packaging however AFAIK, from the ubuntu repo, you should install qt5-default which should install the basics for Qt 5 development.

    I see that someone else had a similar problem with the mint version: https://forum.qt.io/topic/77370/problems-running-opengl-libraries/5
    I will try the installer from the website tomorrow.
    Thanks

    Hi,
    I installed QT from the website, now the OpenGL example compiles without problems --> The Mint people seem to have packaged QT incorrectly.
    I do however get this warning when running the OpenGL example "boxes"

    This demo can be GPU and CPU intensive and may
    work poorly or not at all on your system.

    Is this a general warning? My system is capable enough, core i7 with nvidia gtx770

    Well, seems my problem is solved,
    Thanks, regards,
    Stephan

    What drivers are you using for your card ? The binary from nVidia ?

    yes, the binary drivers, version 375.39 from the Mint repository :-)
    the example runs smooth and the CPU load is below 5%. The compile output suggests that OpenGL is working:
    22:57:54: Starting: "/usr/bin/make"
    gcc -c -pipe -g -Wall -W -D_REENTRANT -fPIC -DQT_QML_DEBUG -DQT_OPENGL_LIB -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I../boxes -I. -I/home/stephan/QT/5.8/gcc_64/include -I/home/stephan/QT/5.8/gcc_64/include/QtOpenGL -I/home/stephan/QT/5.8/gcc_64/include/QtWidgets -I/home/stephan/QT/5.8/gcc_64/include/QtGui -I/home/stephan/QT/5.8/gcc_64/include/QtCore -I. -isystem /usr/include/libdrm -I/home/stephan/QT/5.8/gcc_64/mkspecs/linux-g++ -o fbm.o ../boxes/3rdparty/fbm.c

    and so on. Exits without warnings.

    Don't worry for that warning, it's a message that's currently shown whatever your hardware is. The example itself is pretty old and from a quick look there was a plan to only show it when hardware was underpowered but it seems it didn't happen yet.

    Good to hear. All works well now, including bluetooth (which would have been my next question with the Mint package...)
    Thanks!
