Qt GUI app not running in container. Error : /lib/x86_64-linux-gnu/libQt6Core.so.6: version `Qt_6.8' not found (required by ./<GUI_App>)

Hello,

I am trying to run a QT GUI app inside the docker container. As a frirst step I read few blogs and went with GitHub - arBmind/qtcreator-containers: Docker containers with QtCreator - Ready to develop, build and run Qt Gui applications. to try to run my GUI app.

As am new to this I thought and used same dockerfile and I copied my GUI App and tried running it.

I got the below error:

/lib/x86_64-linux-gnu/libQt6Qml.so.6: no version information available (required by ./<GUI_App>)
/lib/x86_64-linux-gnu/libQt6Core.so.6: version `Qt_6.8’ not found (required by ./<GUI_App>)

Letr I used below lines inside the dockerfile then the first error fixed.

RUN export LD_LIBRARY_PATH=/opt/qtcreator/lib/Qt/lib/:$LD_LIBRARY_PATH
RUN echo ‘export LD_LIBRARY_PATH=/opt/qtcreator/lib/Qt/lib/:$LD_LIBRARY_PATH’ >> ~/.bashrc

But now when I try to run the app again the second/below error I got:

/lib/x86_64-linux-gnu/libQt6Core.so.6: version `Qt_6.8’ not found (required by ./<GUI_App>)

I understood it is version missmatch issue. But since 2 days I have tried many things that i can still issue persists. I failed to fix. Can anyone help m eon this please?

When I see the lib present inside the container it shows below libs :

docker_qt_libs
docker_qt_libs1676×560 164 KB

And I am using below command to run the container :

sudo docker run -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -it <GUI_APP>

The application needs 6.8. But when i try to install 6.8 version it is not allowing to do so. Am I missing anything here? please help.

regards,

How about sharing your Dockerfile and Docker run command or compose file?

The Docker Hub image seems to be up to date with 6.8.1.

Update: sorry, you got a run command, it seems very short compared to the example from the repo:

docker run -it \
    --mount src=/tmp/.X11-unix,target=/tmp/.X11-unix,type=bind \
    --mount src=/mnt/wslg,target=/mnt/wslg,type=bind \
    -e XDG_RUNTIME_DIR=/mnt/wslg/runtime-dir \
    --mount src="$(pwd)",target=/build,type=bind \
    arbmind/qtcreator-gcc-qt:latest \
    qtcreator myproject.qbs

As I said before I used same docker file that is present in that git repo but made some changes :
here is the docker file :
Dockerfile.txt (11.4 KB)

I use below run command :

sudo docker run -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -it <GUI_APP>

I used the same command shown in website but still smae issue.
