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.
The early yearsFree 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 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 in the current development branch several Delphi 2006-specific features have been added, 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 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.
Free Pascal adopted the de facto standard dialect of Pascal programmers, Borland Pascal and, later, Delphi.
