Several additional libraries are required but are not shipped in any form; they must be present on your system:
- SDL 2
- Lua 5.1 (later versions might work, too)
- gettext (required by
)glib
- OpenGL: a hardware driver and library are needed for hardware-accelerated human play, and OSMesa is required for the software-rendering, headless library that machine learning agents will want to use.
- Python 2.7 (other versions might work, too)
