Wails v2

Wails v2 takes its build options as CLI flags, so this stack composes the command rather than running a Taskfile. That is the whole difference from v3 — the stacks are not variations on each other.

  with:
    build-name: myApp
    build-platform: linux/amd64

Platforms

build-platform is passed through to wails build -platform:

linux/amd64      windows/amd64      darwin/universal
linux/arm64      windows/arm64      darwin/arm64

Cross-architecture builds need a matching C toolchain on the runner, because Wails v2 requires cgo. Building linux/arm64 on an amd64 runner without one fails in the assembler, on runtime/cgo.

Build options

build-obfuscate, build-tags and nsis are composed into a single BUILD_OPTIONS string. Tags are de-duplicated, and on Ubuntu 24.04 the webkit2_41 tag is added automatically — that runner ships WebKit 4.1 and Wails needs telling.

- uses: dAppCore/build/actions/build/wails2@v4
  with:
    build-name: myApp
    build-platform: windows/amd64
    build-tags: release
    nsis: true

Disable the automatic tag if you are managing it yourself:

    disable-webkit-auto-tag: true

Signing

See Code signing — macOS notarisation and Windows signtool are both wired, and both are tag-gated.
