Fpc-3.0.4a.intel-macosx.dmg: 2020-07-07: 108.4 MB: 13. Lazarus is a free and open source development tool for the Free Pascal Compiler. The purpose of this. Free Pascal Compiler Support A new OS target is necessary for the compiler. The changes for the target are as following: during assembly the Mac Catalyst platform needs to be specified. Free Pascal is a mature, versatile, open source Pascal compiler. It can target many processor architectures: Intel x86 (16 and 32 bit), AMD64/x86-64, PowerPC, PowerPC64, SPARC, SPARC64, ARM, AArch64, MIPS, Motorola 68k, AVR, and the JVM. Supported operating systems include Windows (16/32/64 bit, CE, and native NT), Linux, Mac OS X/iOS/iPhoneSimulator/Darwin, FreeBSD and other.

Welcome to the FreePascal on the Macintosh page. Here is informationespecially for you who want to write a program for the Macintosh.

News:

  1. I like Free Pascal the most, for beginning I believe it is the best because you don't have too much fancy GUI features to distract you from programming for beginners (algorithms, procedural thinking.). I didn't try to run this on Mac but it should work. I have used Free Pascal.
  2. Free pascal Free Pascal on the Macintosh. Welcome to the FreePascal on the Macintosh page. Here is information especially for you. Target Darwin (Mac OS X). Free Pascal 2.0 for Mac OS X is the current release. It should at least work on Mac OS X 10.1. Target Mac OS (Classic Mac OS).
2005-12-18:
Version 2.0.2 that was released a few weeks ago has all fixes and improvements of the 2.1.1 snapshot that was here (like Mac Pascal style objects and creationof dynamic libraries). Additionally, it doesn't suffer from the installationproblems the 2.1.1 snapshot installer had. Get the release here.
2005-07-23:
The 2.1.1 snapshot that was here is no longer available.
If you really need to be up to date with FPC,please consider using Subversion, and build the compiler by your self.
Some changes:
  • No more '_main' symbol in the system unit (so can link with C main programs)
  • Shared library creation support under Mac OS X
  • Several bugfixes related to overflow checking on PPC
2005-06-29:
There is now awiki page covering porting issues, from traditional macpascals to FPC.
2005-06-21:
A FPC 2.1.1 snapshot is availablehere(10.8 MB, does not include the PDF documentation). It includes:
  • Support for Macintosh Object Pascal in Macpas mode (includes support for mixing in Delphi-style OOP programming in Macpas mode, except that you have to use 'object' instead of 'class' everywhere -- all occurrences of 'class' are simply internally replaced by the OBJECT compiler token)
  • Fixed bug which caused stack corruption in procedures receiving floating point parameters and parameters on the stack (only if the caller side was compiled by FPC)
  • Fixed bug in overflow checking of integer operations (some calculations were buggy if overflow checking is turned on, which is the case in the default development building style of Xcode if you use the integration kit)
  • Fixed bug in division of unsigned numbers > $7fffffff by a power of 2
Should you desire to do so, you can switch back to 2.0 by simply installing the 2.0 package again.
2005-05-15:
At last !!!!! Free Pascal 2.0 is released for Mac OS X and classic Mac OS,as well as for other targets.
This means Free Pascal for the mac is not considered beta anymore.Get it on one of the mirror download sites.

For Mac OS X

final

Target MacOS means classic Mac OS, up to System 9.x.Although it of course also work in the classicenvironment in Mac OS X

MacOS on M68K

not planned

If someone is interrested to contribute, there is apossiblity to implement this target. There is support forMC68000 in the FPC source code, although not updated for a while.

Mac Pascal dialect

The dialect of Pascal supported by popular Pascals on Macintosh is supported in part.Read more here.

Free Pascal 2.0 for Mac OS X is the current release. It should at least work on Mac OS X 10.1 and higher. It requires that you have installedXCode from Apple, to have assembler, linker and make tools available to fpc.For older versions of Mac OS X you should install Apple Development Tools instead.Both can be downloaded for free from Apple, but requires that youregister yourself as a member of Apple Developer Connection.Both are also included in the Mac OS X bundle.

To download, go to the Download page,and choose a mirror site near you (to limit net traffic).The documentation is included, but can also be downloaded separatelly. If you want the source code, it has to be downloaded separatelly.

There most recent FPC 2.1.1 snapshot is availablehere (10.4 MB)with, among others, support for mac style object pascal. See above under NEWS.

Note that the compiler is a unix style program and is run from theTerminal on MacOS X.

Please report any bugs encountered.

Using FPC from XCode

It is possible to use Free Pascal from within XCode (Mac OS X 10.3 is required).Look at the step-by-step instruction of how to download and install theXCode Integration Kit.Thanks to Rolf Jansen for this contribution.

Free Pascal 2.0 for Mac OS is the current release. It will work on latest classic Mac OS (that is 9.2.2) and below, probably down to 7.1.2 (the firstMac OS for PowerPC), and also in the classic compatibility environment on Mac OS X.However it has only been tested on Mac OS 9 and Mac OS X classic environment.

It requires that you have installed Macinstosh Programmers Workshop (MPW)which can be downloaded for free from Apple.

Free pascal download for mac

To download, go to the Download page,and choose a mirror site near you (to limit net traffic).The documentation, as well as the source code (if you need it), has to be downloaded separatelly.

Note that the compiler is an MPW tool.

Please report any bugs encountered.

Current status of classic Mac OS

Native FPC compiler (as an MPW tool)

Almost complete

Unit System.pp

Complete

The system unit is implicitly used by every program. Contains basic file andmemory handling among others.

Unit Dos.pp

Complete

Contrary to what its name suggests, the DOS unit is crossplattfrom and contains utility routines for file and datehandling, beyond that in System.pp. It is reminiscent fromTurbo Pascal.

Unit Sysutils.pp

Planned

A moderner alternative to unit DOS, compatible withDelphi.

Unit MacOS

Complete

API to the Macintosh Toolbox

Units strings objpas heaptrc getopts etc

Implemented.

They are target independent.

Other units

Non-existent. Some will be implemented.

Implementation will depend on how important the unit isand if difficulties arise.

Debugging

Free Pascal Compiler Fpc

There is some limited possibilities to debug programs in classic MacOS. SeeMPW debuggingin the wiki.

As an alternative, you might do the main debugging in a MacOSX/Darwinversion of your program.

There are three major Pascal dialects: Turbo Pascal (extended toDelphi, supported by FreePascal, and partially by Gnu Pascal),Extended Pascal (an ISO standard, supported by Gnu Pascal, DECPascal, Prospero Pascal), and the dialect originating from Apple(commonly used in the Mac community, supported by MPW Pascal,Metrowerks Pascal and Think Pascal). We call this dialect Mac Pascaland there is a special language mode for it: MacPas.

Mode MacPas is a compatibility mode. It is probably notpossible to mimic the Mac Pascal dialect in detail. So the goal is toimplement often used constructs, if this doesn't require too mucheffort, as well as easy-to-implement constructs.

To use MacPas, add -Mmacpas to the command line or insert thecompiler directive {$MODE MACPAS} in the source code.

Note that the mac pascal dialect and mac targets are notinterrelated. It is thus possible to write a mac program with theturbo dialect and to write a Windows program with the mac dialect.

The following are supported:Mac compiler directives like $SETC, $IFC, $ELSEC, $ENDC, $J, $Z.Most of the constructs found in interface files, especiallyApples Universal Interfaces. Cycle, Leave, Otherwise. More is planned.
