x series was widely used, both as an enterprise and educational tool. Stabilizing for a non-beta release began, and version 1.0 was released in July 2000. With release 0.99.8 the Win32 target was added, and a start was made with incorporating some Delphi features. ![]() This release was also ported to systems using a 680x0 processor. This culminated in release 0.99.5, which was much more widely used than previous versions, and was the last release aiming only for Turbo Pascal compliance-later releases added a Delphi compatibility mode. The compiler improved gradually, and the MS-DOS version migrated to the go32v2 extender. The DOS port was adapted for use in OS/2 using the EMX extender which made OS/2 the second supported compilation target - apart from support of Florian Klämpfl as the original author, Daniël Mantione contributed significantly to make this happen and provide the original port of the run-time library to OS/2 / EMX. Later a Linux port was made by Michael van Canneyt, five years before Kylix became available. The initial 32-bit compiler was published on the Internet, and the first contributors joined the project. After two years, the compiler was able to compile itself and became a 32-bit executable. Originally, the compiler itself was a 16-bit DOS executable compiled by Turbo Pascal. Student Florian Paul Klämpfl started developing his own compiler, written in the Turbo Pascal dialect, and produced 32-bit code for the GO32v1 extender, which was used and developed by the DJGPP project at that time. History The early yearsįree Pascal emerged when Borland made it clear that Borland Pascal development for MS-DOS would stop with version 7, to be replaced by a Windows-only product (which became Delphi later on). The current trunk (2.7.1) version implements basic ISO Pascal mode, though many things such as Get and Put procedure and file buffer variable concept for file handling are still missing. The development branch also features an “Objective-Pascal” extension for Objective-C ( Cocoa) interfacing. ![]() ![]() ![]() The project still lacks the Delphi functionality of compiler-supported exporting of classes from shared libraries, which is for example useful for Lazarus, which implements packages of components.Īs of 2011 several Delphi 2006-specific features have been added in the current development branch, and some of the starting work for the features new in Delphi 2009 (most notably the addition of the UnicodeString type) has been done. x release series does not significantly change the dialect objectives beyond Delphi 7, instead they aim for closer compatibility. Since the Apple dialect implements some standard Pascal features that Turbo Pascal and Delphi omit, Free Pascal is a bit more ISO-compatible than these. In fact, the project has a compilation mode concept, and the developers made it clear that they would incorporate working patches for the ANSI/ ISO standardized dialects to create a standards-compliant mode.Ī small effort has been made to support some of the Apple Pascal syntax, to ease interfacing to Mac OS and Mac OS X. From version 2.0 on, the Delphi 7 compatibility has been continuously implemented or improved. 11.4 Sites specialized in game developmentįree Pascal adopted the de facto standard dialect of Pascal programmers, Borland Pascal and, later, Delphi.7 Integrated development environments (IDEs).2.4 Consolidation: the 2.2.x release series.
