The principal problems were that adding processors basically meant rewriting the code generator, and that the register allocation was based on the principle of always keeping three free registers between building blocks, which was inflexible and hard to maintain.įor these reasons, FPC 1.1.x branched from the 1.0.x main branch in December 1999.

For the 1.0.x releases, the port to 680x0 CPUs was redone, and the compiler produces stable code for a number of 68k Unixes and AmigaOS.ĭuring the stabilisation of what would become 1.0.x, and specially when porting to the m68k systems, it was clear the design of the code generator was far too limited in many ways. The 1.0.x series (and the bug-fix/stabilisation releases that followed, last, 1.0.10 in July 2003) was widely used, both as an enterprise and educational tool. Stabilising for a 1.0 release started, and this milestone was reached in July 2000. With 0.99.8, the Win32 target was added, and a start was made with incorporating some Delphi features. 0.99.5 was also ported to systems using a 680x0 CPU. This culminated in the 0.99.5 release that was much more widely used than the versions before, and the last release aiming only for Turbo Pascal compliance: later releases would add a Delphi compatibility mode. The DOS version also improved gradually, and migrated to the go32v2 extender.

In the years after publishing on the Internet, a Linux port was made by Michael van Canneyt (a full five years before Kylix), the DOS port was adapted for use in OS/2 through the EMX extender. The initial 32-bit compiler was published on the net, and the first contributors joined the project. After two years, the compiler was able to compile itself so it became 32-bit too.

Originally the compiler itself was a 16-bit DOS executable compiled by Turbo Pascal. The compiler was written in the (Borland) Turbo Pascal dialect from the start and produced 32-Bit code for the go32v1 DOS extender used and developed by the DJGPP project at this time. Would be a Windows-only product (which became Delphi later on), and a student (Florian Paul Klämpfl) started working on his own compiler. Lazarus, which implements packages of components).įree Pascal emerged when Borland made clear there would be no Borland Pascal 8, and the next version The project still has missing Delphi functionality, mainly compiler supported exporting of classes from shared libraries (useful for e.g. The 2.2.x series doesn't significantly change the dialect objectives beyond D7, instead aiming for close compatibility. Since the Apple dialect implements some of the Standard Pascal features that TP/Delphi miss, FPC is a bit more ISO compatible than these.

However, the project has a compilation mode concept, and the developers made it clear that they would incorporate working patches for the ANSI/ISO standardised 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 (X). (Specifically: Borland Pascal 7 and Delphi 2 for version 1.0.x, and for version 2.0.x the target versions for the Delphi compatibility changed to 6/7).

4 Applications software produced with Free Pascal.3.1 Version 2.3.x (development version).The visual parts of the Delphi libraries (the VCL) and the creation of a visual IDE and RAD are part of a separate project, Lazarus. FPC supports multiple architectures and notations in the internal assembler. Like Turbo Pascal and Delphi, Free Pascal has excellent support for integration of assembly language in the Pascal code. This IDE deteriorated for some time because of a missing maintainer, but in a common effort in the second half of 2005 and the first months of 2006, most major bugs were fixed and the IDE became release-worthy again. To avoid this confusion, at the end of 1997 the name of the project was changed into Free Pascal Compiler (FPC).įree Pascal comes with a text mode IDE resembling Turbo Pascal's IDE. Writing "Compiler" with K is uncommon in German. FPK Pascal never meant "Free Pascal Kompiler". The 32/64-bit architecture and multi-operating system compiler implements the Pascal dialects (Turbo Pascal and Delphi) as well as some MacPascal constructs, and is available forįree Pascal used to be known as FPK Pascal, since FPK are the initials of the author, Florian Paul Klämpfl. Users who will compromise its status may be blocked.įree Pascal (or FPK Pascal or FPC) is a free, portable, open source, Pascal and Object Pascal compiler.
