Building the Daemon

Managing the AutomateLinux daemon build process is streamlined through shell functions and a core build script.

The bd Terminal Function

The fastest way to rebuild the daemon from anywhere in the terminal is the bd function.

bd

What bd does:

1. Temporarily changes directory to the daemon source folder.
2. Runs the build script using the bs (build-source) alias.
3. Returns to your original directory.

The Build Script (daemon/build.sh)

The underlying logic resides in daemon/build.sh. It performs high-level system maintenance alongside the compilation:

1. Stop Daemon: Runs stop_daemon.sh to ensure no active process holds files.
2. Socket Setup: Ensures /run/automatelinux exists with correct permissions (required for Unix Domain Socket communication).
3. CMake Build:
   • Enters the build/ directory.
   • Executes cmake ...
   • Executes make.
4. Deployment:
   • Copies the resulting daemon binary back to the root of the daemon directory.
   • Reloads systemd configs: sudo systemctl daemon-reload.
   • Restarts the service: sudo systemctl restart daemon.service.

Technical Requirements

• Permissions: The build process frequently calls sudo for systemd and socket management.
• Dependencies: Requires cmake, libevdev, libsystemd, and libmysqlclient.
• UDS Path: The daemon communicates via /run/automatelinux/automatelinux-daemon.sock.

[!IMPORTANT] Always use bd rather than calling make directly in the build/ folder to ensure the binary is correctly deployed and the systemd service is refreshed.
