Hi, In essence, is the same. To have all complete version running (in 1.4), you should execute: Gofer it squeaksource:'Alien' ; package: 'ConfigurationOfOldAlien'; load. ((Smalltalk globals classNamed: 'ConfigurationOfOldAlien') project version: #stable) load. This will load FFI and Alien (who allows the callback stuff). Then you can look for the examples. (yes... this is an ugly and low-documented issue... we should improve in that area this year) Esteban On Jun 6, 2012, at 11:02 AM, Raffaello Giulietti wrote:

Hello,

is there documentation and/or examples about Pharo's Foreign Function Interface? Is FFI inherited from Squeak's (http://wiki.squeak.org/squeak/1414)?

Thanks Raffaello Giulietti
