# Docker file for building Overte Qt5 packages for Ubuntu 20.04

# Some steps for actually using this:
# - Check which commit you are building https://invent.kde.org/qt/qt/qt5/-/tree/kde/5.15
# - Adjust this file to include the commit hash you are building, the date, the number of threads you want to use (-j10), the platform, and the Qt and QtWebEngine versions.
#     Keep in mind that building Qt requires a lot of memory. You should have over 1.2GiB of system memory available per thread.
# - Run the build process with something like `PROGRESS_NO_TRUNC=1 DOCKER_BUILDKIT=1 BUILDKIT_STEP_LOG_MAX_SIZE=-1 docker build --progress plain -t overte-qt5:5.15.10-2023.10.01-kde_d2122ee587cceb5b2f4130b7074f86db9aca570e -f Dockerfile_Ubuntu_20.04_Qt5 .`
#     Buildkit is used to cache intermittent steps in case you need to modify something afterwards.
# - Once the build has completed, create a container from the image and export the created Qt package.
#     `docker create --name extract overte-qt5:5.15.10-2023.10.01-kde_d2122ee587cceb5b2f4130b7074f86db9aca570e`
#     `docker cp extract:qt5-install-5.15.10-2023.10.01-kde_d2122ee587cceb5b2f4130b7074f86db9aca570e-ubuntu-20.04-amd64.tar.xz /path/on/host`
#     `docker rm extract`
