Dæmon engine code

Sources

The Dæmon engine code features C++ and C code.

See the Getting the source page for details on how to get the sources.

The engine sources are stored in a Git repository: github.com/DaemonEngine/Daemon

Libraries

We maintain various libraries and tools that contribute to the Dæmon engine:

• Native Client runtime — A binary sandbox to securely run downloadable game code, built separately, distributed with the engine.
  Sources: github.com/DaemonEngine/native_client
• Dæmon Crunch — An GPU-friendly image codec, built in engine (submodule).
  Sources: github.com/DaemonEngine/crunch
• Dæmon Breakpad — A crash reporting library, built in engine (submodule).
  Sources: github.com/DaemonEngine/breakpad

We also vendor as submodules some third-party libraries, they are usually kept unmodified but we keep the opportunity to patch them when needed so we host them in our forge:

• PDCursesMod — A curses library used everywhere ncurses isn't available, built in engine (submodule).
  Sources: github.com/DaemonEngine/PDCursesMod
• FreeType — A font rendering engine, built in engine (submodule).
  Sources: github.com/DaemonEngine/freetype
• GoogleTest — A C++ test framework, used in engine build system (submodule).
  Sources: github.com/DaemonEngine/googletest

We also vendor as subdirectories some small third-party libraries, they may be modified when needed:

• FindLocale: github.com/DaemonEngine/Daemon/tree/master/libs/findlocale
• TinyFormat: github.com/DaemonEngine/Daemon/tree/master/libs/tinyformat
• Minizip: github.com/DaemonEngine/Daemon/tree/master/libs/minizip
• Mumblelink github.com/DaemonEngine/Daemon/tree/master/libs/mumblelink

Platforms

The Dæmon engine is distributed as native executables, compiled for each supported architectures and systems. The engine is written to be buildable for various supported and not-supported platforms. We provide prebuilt binaries of the engine for the supported platforms with the Unvanquished game, the engine for a not-supported platforms should be built by the user:

The compiled game code to run with the Dæmon engine is meant to be distributed as Native Client executables, compiled for various architectures but system-agnostic:
