miqt-docker - Go Packages (original) (raw)

miqt-docker

This is an optional helper program to quickly run a dockerized MIQT cross-compiler environment. Many containers are available targeting different OSes and Qt versions.

It also has some built-in commands that can be run either dockerized or natively.

Usage

Run miqt-docker with no arguments to see full usage instructions and all available embedded dockerfiles:

Usage: miqt-docker ENVIRONMENT COMMAND...

COMMAND may be any shell command (e.g. go build); or /bin/bash to get an
interactive terminal; or one of the following predefined tasks:

  -build           Run 'go build' with usual MIQT flags
  -minify-build    Run 'go build' with special minification flags
  -windows-build   Run 'go build' with special Windows support
  -android-build   Build an Android APK (using the android-qt5 or android-qt6
                    container environments)

Environment variables:
  DOCKER           Override the path to docker
    
Available container environments: (use - as wildcard character)
  [...]

You can specify the environment using a short form of the name. For example,win64-static will be expanded to the regex /win64.+static/ and pick the best available match with the highest version number (win64-cross-go1.24-qt6.8-staticat time of writing). This allows you to pin platforms and major versions in build commands while automatically upgrading to minor versions.

Example build commands:

miqt-docker macos go build -ldflags '-s -w'
miqt-docker native -minify-build
miqt-docker win64-qt6-static -windows-build
miqt-docker win64-qt6-static /bin/bash
miqt-docker android-qt6 -android-build

Comparison to manual Docker commands

You can create a dockerized MIQT build environment yourself using the Dockerfiles in the docker/ directory. The benefit of miqt-docker is:

Embeds all available MIQT docker containers
Use glob matches to automatically pick the highest version container for target
Automatically build new docker containers or reuse existing, based on content hash of the Dockerfile
Consistently named docker images across multiple projects using MIQT
Automatically bind source code volume from current go.mod / go.work / git repository and preserve relative working directory
Handles bind-mounting the GOCACHE and GOMODCACHE directories for fast rebuilds
Handles using the proper uid+gid on Linux
Automatically detect sudo requirement on Linux
Convenient predefined tasks
Advanced build support for Android
