This prebuilds aurora (and all its dependencies) as static libraries on linux (similar to windows) during the appimage build rather than on the users install. This drastically reduces required appimage install buildtime libraries/headers on the users system (likely to none) and is the ultimate solution to a portable linux build in combination with other merged PRs. (it also reduces the build time since it shifts around half of the build to the CI rather than the user).

Summary by CodeRabbit

  • New Features

    • Added support for creating and using precompiled native packages during Linux setup and local builds.
    • Added an option to specify a native prebuilt package directory during installation.
    • AppImage builds now bundle validated native packages and preserve incremental build caches across mounts.
  • Bug Fixes

    • Improved detection of stale or missing build tools and cached packages.
    • Resolved thread-linking requirements for packaged graphics dependencies.
    • Added required Linux dependencies for AppImage and SDL3 builds.

adds symlinks to the compiler locations in a static path that way rebuilds do not think that the compiler path has changed between appimage install commands

📝 Walkthrough

Walkthrough

The change adds a Linux native-prebuilt package builder, integrates package paths into setup and local builds, and updates AppImage packaging to reuse validated packages and stable cache paths.

Changes

Linux native prebuilt workflow

Layer / File(s) Summary
Native package generation
Launcher/Prepare-NativePrebuilt.sh
The new script fingerprints source and configuration inputs, builds the dependency closure, harvests libraries and headers, generates relocatable CMake metadata, and records provenance.
Native package build integration
Launcher/local-build.sh, Launcher/WiiCompiled.Setup.Linux/BuildRunner.cs, Launcher/WiiCompiled.Setup.Linux/Program.cs, runtime/cmake/NativePrebuilt.cmake
Setup and local builds accept and validate --native-prebuilt-dir. Cache reuse checks tool paths. Path-based compiler tools receive explicit LLVM settings. Prebuilt Dawn targets load after Threads discovery.
AppImage packaging and runtime reuse
Launcher/build-appimage.sh, .github/workflows/package.yml
AppImage builds prepare or reuse architecture-specific native packages, track dirty workspaces with timestamps, create stable cache symlinks, and install required Linux build dependencies.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to d895e

The build changes can still omit the final native target or resolve a relative prebuilt-library path differently between build stages, leading to incomplete or failed Linux packages. These bounded correctness issues should be addressed or explicitly accepted before merging.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Normalize --native-prebuilt-dir to an absolute path.

assert_file resolves the value against the current working directory, but the value is later passed to CMake as MKW_NATIVE_PREBUILT_DIR (Line 415). A relative value passes validation here and then resolves differently inside CMake, because CMake resolves a relative path in include()/path use against the source directory, not the caller's working directory. Other directory options in this script are already absolutized.

🛠️ Proposed fix
 if [[ -n "$native_prebuilt_dir" ]]; then
+    native_prebuilt_dir=$(cd "$native_prebuilt_dir" 2>/dev/null && pwd) \
+        || fail "Native prebuilt package directory is missing: $native_prebuilt_dir"
     assert_file "$native_prebuilt_dir/native_prebuilt.cmake" "Native prebuilt package"
