Docker images for QtCreator

This project builds Docker images with QtCreator and various compilers used to build and debug C++ and Gui applications using WSL and Docker.

Usage

Prerequiste: X server (Linux with X, Win11 or VcXsrv)

To run on Windows 11 you need to mount some special directories to enable fast graphics rendering and X11 communications.

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

To use clang instead of gcc use this:

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-clang-libstdcpp-qt:latest \
    qtcreator myproject.qbs

Description:

• define the display variable to use Docker
• mount the current directory to the /build folder
• use the qtcreator-clang-qt image in the latest variant
• start the qtcreator with myproject.qbs

If you want to do more work on the project, we recommend to use a docker-compose.

Details

The Dockerfile is multi staged and has different targets for all the variants. All targets with underscores are meant to be internally only.

Note: The Clang Qt combination is missing because the Qt Company does not publish binaries built for libc++

QtCreator is preconfigured to run Gui applications properly.

To support your development the user is non-root. You may still install extra software with sudo if you need.
