What is Lazarus?
Free Pascal is a GPL-licensed compiler that operates on Linux, Win32, OS/2, 68K, and other operating systems. Designed to comprehend and compile Delphi syntax, it naturally supports OOP. Lazarus is the missing piece of the puzzle, enabling you to develop Delphi-like programs across all the aforementioned platforms. Unlike Java's "write once, run anywhere" philosophy, Lazarus and Free Pascal aim for "write once, compile anywhere." With the exact same compiler available for all these platforms, you can produce identical products for different systems without any need for recoding. Lazarus is entirely API-independent. Programs can be compiled for Win32, GTK2, Qt, Carbon, FpGUI, and other custom widget sets, with GTK2 and Qt also supported on Windows.
The LCL closely resembles the VCL, allowing for significant reuse of Delphi code.
How to use Lazarus?
Lazarus is a Delphi-compatible, cross-platform IDE based on the Free Pascal compiler, enabling 'write once, compile anywhere' to help developers quickly build apps that run on multiple OSes and processor architectures.
