Building

Prerequisites

Dependency Version Notes
CMake >= 3.22 Build system
Ninja any Recommended generator (make works too)
C++ compiler C++20 GCC 12+ or Clang 15+
Qt 6 >= 6.4 Core, Quick, Svg, DBus, Widgets, Concurrent, Test, QuickTest
libudev any Device discovery via udev/hidraw
Google Test any Test framework (Ubuntu ships source only — needs manual build)
pkg-config any Finds libudev

Qt 6 Modules

The project uses these Qt 6 modules (from CMakeLists.txt):

find_package(Qt6 REQUIRED COMPONENTS Core Quick Svg DBus Widgets Concurrent Test QuickTest)

Plus these QML modules at runtime:

  • qml6-module-qtquick, qml6-module-qtquick-controls, qml6-module-qtquick-layouts
  • qml6-module-qtquick-window, qml6-module-qtquick-templates
  • qml6-module-qtquick-dialogs, qml6-module-qt5compat-graphicaleffects
  • qml6-module-qttest (for QML tests)

The canonical lists live in .github/workflows/ci.yml. If something below drifts, the CI file wins — it's what actually builds every PR.

Build from Source

git clone https://github.com/logitune/logitune.git
cd logitune

# Configure + build
make build

# Run with debug logging
make run

The make build target runs:

cmake -B build -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -Wno-dev
cmake --build build -j$(nproc)

Build Commands

The Makefile provides these targets:

Command Description
make build Build the project (Debug mode)
make run Build and run the app with --debug (host only)
make test Run C++ unit/integration tests
make test-qml Run QML component tests
make test-tray Run tray manager tests
make test-all Run all test tiers
make package-deb Build a .deb package
make package-rpm Build an .rpm package
make package-arch Build an Arch package
make install Install to system (/usr/local)
make uninstall Remove system install
make release Version bump, tag, push
make setup-hooks Install git pre-push hook (now a no-op: cmake -B build auto-activates hooks/ via core.hooksPath)
make clean Remove build artifacts
make help Show all targets

CMake Options

Option Default Description
BUILD_TESTING ON Build test binaries
BUILD_HW_TESTING OFF Build hardware integration tests (requires connected device)
CMAKE_BUILD_TYPE Debug Debug or Release

Native Package Builds

Ubuntu / Debian (.deb)

make package-deb
sudo apt install ./logitune-VERSION_amd64.deb

The .deb package installs the binary, udev rules (71-logitune.rules), and .desktop file. udev rules are activated automatically on install, so no manual udevadm steps are required.

Fedora / RHEL (.rpm)

make package-rpm
sudo dnf install logitune-VERSION.rpm

Arch Linux

make package-arch   # builds with makepkg

Or install from AUR directly. The package installs udev rules and reloads them via a post_install hook.

System Install from Source

make install    # installs to /usr/local, copies udev rules, reloads udev
make uninstall  # removes all installed files

Devcontainer / GitHub Codespaces

The repository includes a devcontainer configuration for one-click development in VS Code or GitHub Codespaces.

What's Included

The Dockerfile (/.devcontainer/Dockerfile) builds an Ubuntu 24.04 container with:

  • All build dependencies (Qt 6, CMake, Ninja, GTest, libudev)
  • Development tools (clangd, gdb, fish shell, bat, eza, ripgrep, fzf)
  • Nerd Font for terminal icons
  • QT_QPA_PLATFORM=offscreen for headless testing

VS Code Extensions

The devcontainer auto-installs:

  • llvm-vs-code-extensions.vscode-clangd — C++ language server
  • ms-vscode.cmake-tools — CMake integration
  • theqtcompany.qt, theqtcompany.qt-qml, theqtcompany.qt-cpp — Qt/QML support
  • vscode-icons-team.vscode-icons — file icons

Post-Create

On container creation, postCreateCommand runs:

make setup-hooks
sudo rm -rf build
cmake -B build -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=ON
cmake --build build -j$(nproc)

The sudo rm -rf build clears any host-side build directory that might have leaked in through the bind mount before running a fresh in-container configure.

So the project is fully built and ready to test immediately after the container starts.

Limitations

The devcontainer runs headless (QT_QPA_PLATFORM=offscreen), so:

  • All tests run fine (C++, QML, tray)
  • You cannot run the GUI application visually
  • No hidraw access (no physical device tests)

CI Pipeline

The CI workflow (.github/workflows/ci.yml) runs on every push to master and every pull request:

graph LR
    A[Push / PR] --> B[Install Dependencies]
    B --> C[Configure CMake]
    C --> D[Build]
    D --> E[C++ Tests]
    D --> F[Tray Tests]
    D --> G[QML Tests]
    E --> H{All Pass?}
    F --> H
    G --> H
Loading

The release workflow (.github/workflows/release.yml) triggers on version tags (v*):

graph LR
    A[Tag Push v*] --> B[Build .deb]
    A --> C[Build .rpm]
    A --> D[Build Arch package]
    B --> E[GitHub Release]
    C --> E
    D --> E
Loading

It builds native packages for each distro family and creates a GitHub Release with auto-generated release notes.
