Free Pascal 3.2.2

Pascal compiler with integrated development tools

Free Pascal is an open-source compiler for building native programs in Pascal. It supports 32-bit and 64-bit compilation and targets processor families including x86, x86-64, ARM, PowerPC and SPARC. Its integrated environment supports writing, compiling and debugging code, while modular units help organize larger projects. The compiler can also combine Pascal with assembly language.

Free Pascal for Windows 10 - Full description

Free Pascal is an open-source compiler for the Pascal programming language, intended for developers learning Pascal as well as those building and maintaining larger applications. It compiles Pascal source code into native programs and supports both 32-bit and 64-bit development. Its compiler targets several processor families and operating systems, making it useful for projects that need to run beyond a single type of computer.

The compiler organizes code into units, so related routines and identifiers can be kept within separate modules instead of sharing one program-wide namespace. This helps keep projects structured as they grow and reduces naming conflicts between components. When source files change, Free Pascal can determine which units need to be rebuilt, avoiding the need to manage a traditional Makefile for routine compilation. Its emphasis on fast compilation also supports a short edit, compile and test cycle, including for larger codebases.

Free Pascal includes an integrated development environment for writing, compiling and debugging programs. Developers can work with source code and build output in one environment rather than switching between separate tools for each basic task. The compiler also integrates assembly language with Pascal, allowing lower-level routines to be combined with Pascal code where a project calls for that approach. This gives programmers room to work at different levels while keeping much of an application in Pascal.

The tool can be used for learning programming fundamentals, creating standalone applications, maintaining existing Pascal software and developing code for supported processor and operating-system targets. Its modular design suits projects divided into reusable units, while its native compilation and debugging workflow can help with iterative development. Support for targets such as x86, x86-64, ARM, PowerPC and SPARC makes it relevant to cross-platform and embedded development, subject to the available target support and toolchain.

Free Pascal is free and open source. The supplied Windows package is intended for Windows development; the compiler project also supports systems including Linux, FreeBSD, macOS, DOS, Windows, Windows CE, OS/2, NetWare and MorphOS. The compiler is a programming tool rather than a finished application, so users need Pascal source code and a development goal. The included IDE provides a starting point for editing and debugging, while projects can also use the compiler as part of a build workflow.
