🧱 Build Instructions

KoggerApp is a cross-platform C++ Qt QML project, built with CMake (CMake ≥ 3.22, Qt 6.8.3, C++23). You can build it on Windows, Linux, and Android using the appropriate Qt kits and compilers. The easiest way is to open the top-level CMakeLists.txt in Qt Creator, select a kit, and build; a command-line example is given for Linux below.

🪟 Windows (x86_64):
Compiler: LLVM-MinGW 17.0.6
Qt version: Qt 6.8.3 (llvm-mingw_64)
Steps:

• Open CMakeLists.txt in Qt Creator (File > Open File or Project)
• Select the LLVM-MinGW 64-bit kit
• Build > Build Project (Qt Creator runs CMake configure automatically)
• Run from Qt Creator or find KoggerApp.exe under build/

🤖 Android (armeabi-v7a, arm64-v8a)
Compiler: Clang from NDK 27.3.13750724
Qt version: Qt 6.8.3 (android_arm64_v8a)
Set up the Android SDK/NDK in Qt Creator (Tools > Options > Devices > Android)
Steps:

• Open CMakeLists.txt in Qt Creator
• Select the Android (arm64-v8a) kit — a single kit produces a universal APK with both ABIs; keep the android_armeabi_v7a Qt installation present for the second-ABI sub-build
• Build > Build Project
• Install the generated .apk on a device

🐧 Linux (Ubuntu x86_64)
Compiler: Clang 18.1.3
Qt version: Qt 6.8.3 (gcc_64)
Clone and build (set CMAKE_PREFIX_PATH to your Qt installation):

git clone https://github.com/koggertech/KoggerApp.git
cd KoggerApp
cmake -S . -B build -G Ninja \
      -DCMAKE_BUILD_TYPE=Release \
      -DCMAKE_PREFIX_PATH="$HOME/Qt/6.8.3/gcc_64"
cmake --build build -j"$(nproc)"
./build/KoggerApp
