A manual in French is being written, it will be translated when it is advanced enough. In the meantime, you can translate it with online tools.

Distribution	Package
Flatpak
Archlinux

Any help to create packages for different distributions is welcome.

If you want to contribute, you'll need to install from source

• gtk3 >= 3.20
• python3
• python-gobject
• gobject-introspection
• mido (python-mido (AUR) on archlinux)
• SciPy (python-scipy on archlinux)
• Charset Normalizer (python-charset-normalizer on archlinux)
• NumPy (python-numpy on archlinux)
• ifaddr (python-ifaddr on archlinux)
• pySerial (python-pyserial on archlinux)
• pyzmq (python-pyzmq on archlinux)
• Textual (python-textual on archlinux)
• Rich (python-rich on archlinux)

Install olc dependencies:

$ sudo apt install meson python3-setuptools gobject-introspection cmake libgirepository1.0-dev libgtk-3-dev python-gi-dev python3-cairo-dev python3-gi-cairo python3-liblo python3-mido python3-rtmidi gettext python3-scipy python3-charset-normalizer python3-numpy python3-ifaddr python3-serial python3-zmq python3-textual python3-rich

$ git clone https://github.com/mikacousin/olc.git
$ cd olc
$ meson setup builddir --prefix=/usr/local
$ sudo ninja -C builddir install

You can execute the software:

$ olc

Open Lighting Console includes several helper utilities installed alongside the main application to monitor network packages, benchmark performance, or run headless servers:

• olcd (OLC Daemon): A headless version of Open Lighting Console (WIP, currently used only for testing purposes). It initializes and runs the CoreEngine without a graphical interface, listening and reacting to OSC messages.
• olc-monitor (OLC Monitor): An interactive terminal user interface (TUI) based on textual and zmq that streams real-time DMX channel values and frequency statistics from a running olcd or olc process.
• sacn-monitor (sACN Monitor): A modern GTK4/Adwaita graphical utility for passive network packet monitoring of sACN streams. It displays active sources, their priorities, and renders a 3D intensity grid of the 512 DMX channels.
• olc-bench (OLC Benchmarking): A stress-testing tool that measures the machine's performance limit by incrementally simulating active DMX universes to find the maximum stable universe count at a target 44Hz frequency.
