This portal provides an overview of development for different Linux distributions with Lazarus and Free Pascal.
Linux is one of the earliest platforms that have been supported by Lazarus and Free Pascal. The heterogeineity of Linux distributions and hardware implementations, however, is a challenge for software development. The hints that are provided on the pages linked from here may help to overcome these difficulties.
Basic development techniques with Lazarus and Free Pascal are described here, as well as hints for special optimization approaches.
FPC and Lazarus support several APIs and Libraries on Linux.
