TechnoRunner

Native (C++/Qt 6) bootstrapper for the Technopark / glitchless Minecraft launcher. On first run it downloads an OS/arch-matched JRE and the launcher JAR into <app-data>/.minecraft/technomine, verifies the JAR's SHA-256, then launches it.

Build

Requires Qt 6 (Widgets, Network, Test), CMake ≥ 3.21, and libarchive.

# Linux: deps via apt — sudo apt install cmake qt6-base-dev qt6-base-dev-tools libarchive-dev
# Windows: libarchive via vcpkg (see vcpkg.json); pass the vcpkg toolchain file to cmake.
cmake -B build -S .
cmake --build build
ctest --test-dir build --output-on-failure   # set QT_QPA_PLATFORM=offscreen when headless

Run: ./build/TechnoRunner

Running a release build on macOS

The .dmg ships an ad-hoc signed (but not notarized) Minecraft.app. The bundle's dylibs/frameworks are validly signed, so once the download quarantine flag is cleared the app launches on any Apple Silicon Mac. After dragging it to Applications:

xattr -cr /Applications/Minecraft.app   # clear the download quarantine flag, then open it

Right-clicking the app → Open also works on most macOS versions. (Full Gatekeeper trust without this step would require a Developer ID certificate + notarization.)

Layout

• src/ — application sources (util/, models/, net/, run/, app/, ui/, main.cpp)
• tests/ — Qt Test unit tests (one executable per component)
• resources/ — embedded images (background.jpeg, close-btn.png) + macOS bundle assets
• .github/workflows/build.yml — cross-platform build/test/release (Linux AppImage, Windows zip, macOS dmg)

History (Kotlin/Swing runner + native C bootstrap) lives in git before the qt-rewrite branch.
