Features

The language syntax has excellent compatibility with TP 7.0 as well as with most versions of Delphi (classes, rtti, exceptions, ansistrings, widestrings, interfaces). A Mac Pascal mode, largely compatible with Think Pascal and MetroWerks Pascal, is also available. Furthermore Free Pascal supports function overloading, operator overloading, global properties and several other extra features.

Requirements

x86 architecture:

For the 80x86 version at least a 386 processor is required, but a 486 is recommended. The Mac OS X version requires Mac OS X 10.4 or later, with the developer tools installed.

PowerPC architecture:

Any PowerPC processor will do. 16 MB of RAM is required. The Mac OS classic version is expected to work System 7.5.3 and later. The Mac OS X version requires Mac OS X 10.3 or later (can compile for 10.2.8 or later), with the developer tools installed. On other operating systems Free Pascal runs on any system that can run the operating system.

ARM architecture

16 MB of RAM is required. Runs on any ARM Linux installation.

Sparc architecture

16 MB of RAM is required. Runs on any Sparc Linux installation (solaris is experimental).

License

The packages and runtime library come under a modified Library GNU Public License to allow the use of static libraries when creating applications. The compiler source itself comes under the GNU General Public License. The sources for both the compiler and runtime library are available; the complete compiler is written in Pascal.
