Firebird Emu

This project is currently the community TI-Nspire emulator, originally created by Goplat.
It supports the emulation of Nspire Touchpad (CAS), CX (CAS) and CX II (-T/CAS) calcs on Android, iOS, Linux, macOS and Windows.

Building

First, install Qt 6 and CMake (desktop build).
Then run:

python3 tools/build/bootstrap.py --target desktop --bootstrap-kddockwidgets --yes
cmake -S . -B .build/desktop
cmake --build .build/desktop -j8

Single CMake driver (all platforms from one entrypoint):

python3 tools/build/bootstrap.py --target all --yes
cmake -S . -B .build/meta -DFIREBIRD_META_BUILD=ON
cmake --build .build/meta --target firebird-build-all --parallel

Local host matrix:

1. macOS: macos, linux, windows, android, ios, web
2. Linux: linux, windows, android, web
3. Windows: windows, linux, android, web

For Linux/Windows desktop cross-builds, bootstrap prepares local Docker builder images. Docker must be installed and running for those cross desktop builds. Android local builds also require an Android NDK; bootstrap installs one via sdkmanager and reports ANDROID_NDK_ROOT status.

Build specific platforms only:

cmake -S . -B .build/meta -DFIREBIRD_META_BUILD=ON -DFIREBIRD_TARGETS="desktop;web"
cmake --build .build/meta --target firebird-build-all --parallel

Notes:

1. Build artifacts are expected under .build/ (single root build folder).
2. Desktop default build enables the KDDockWidgets backend.
3. If KDDockWidgets is not present yet, bootstrap it to .build/deps/kddockwidgets-2.4: python3 tools/build/bootstrap.py --target desktop --bootstrap-kddockwidgets --yes
4. If your local build dir was configured before this default changed, rerun configure with: cmake -S . -B .build/desktop -DFIREBIRD_ENABLE_KDDOCKWIDGETS=ON
5. Optional vcpkg toolchain: python3 tools/build/bootstrap.py --target desktop --with-vcpkg --bootstrap-vcpkg --yes then configure with -DCMAKE_TOOLCHAIN_FILE=.build/vcpkg/scripts/buildsystems/vcpkg.cmake
6. Optional CI fallback (disabled by default in meta-build): -DFIREBIRD_ENABLE_CI_FALLBACK=ON

Platform-specific CI paths:

1. Linux: .github/workflows/main.yml
2. Windows: .github/workflows/windows.yml
3. macOS: .github/workflows/macOS.yml
4. iOS: .github/workflows/ios.yml
5. Android: .github/workflows/android.yml
6. Web (Emscripten): .github/workflows/web.yml

Bootstrap helper:

1. Dependency checker/installer: tools/build/bootstrap.py
2. Usage: tools/build/README.md
