Once launched, clicking on the desktop will show a menu containing entries for OpenPonk.


On Windows or with 64b OpenPonk, you should not need any additional prerequisities.

32b OpenPonk on Linux may require extra configuration. Please refer to Pharo’s [official guide](

Additionally you will require 32bit cairo2 library, usually available in distribution package managers as libcairo2:i386 (debian), libcairo2, etc.

The bundled launcher will check those requirements and will warn you and provide some tips if your system is not configured properly.
