This session will explain the current state of the open source free pascal compiler (FPC) and assiciated Lazarus IDE. I will describe the tools, where to get them, and how to install them.
The second part of session will focus on the migration of existing Delphi (and Kylix) projects to FPC with special focus on database programs using Firebird.
Originally proposed as two sessions, this talk is about the API, its workings and the interface. I will demonstrate with some applications how we can use API in Delphi, Lazarus and Free Pascal.
