Free Pascal is a 32, 64 and 16 bit professional Pascal compiler. It can target multiple processor architectures: Intel x86, AMD64/x86-64, PowerPC, PowerPC64, SPARC, and ARM. Supported operating systems include Linux, FreeBSD, Haiku, Mac OS X/iOS/Darwin, DOS, Win32, Win64, WinCE, OS/2, MorphOS, Nintendo GBA, Nintendo DS, and Nintendo Wii. Additionally, support for the JVM, MIPS (big and little endian variants), i8086, Motorola 68k and AArch64 architectures is available in the development versions.

Some FPC users have observed issues with delivery of e-mails from FPC (and other) mailing lists. Yahoo has decided to implement a DMARC policy, which effectively disallows the use of e-mail accounts hosted by them to subscribe to mailing lists. Unfortunately, none of the proposed solutions for mailing lists are usable at this point in time.
Note that not only Yahoo (and AOL) e-mail accounts are affected, but also e-mail accounts hosted by other companies that have implemented DMARC policy support, because they have to respect the Yahoo's DMARC policy (blocking mailing lists) and thus they reject e-mails sent from Yahoo addresses to the mailing lists. Addresses from such DMARC-compliant providers may be in turn also be disabled and/or unsubscribed by the mailing list software when their mail servers start rejecting e-mails sent from Yahoo addresses to the mailing lists. Among others, such providers includes e.g. Microsoft (hosting e.g. outlook.com and hotmail.com addresses).
Version 2.6.4 is the latest stable version the Free Pascal. Hit the download link and select a mirror close to you to download your copy. The development releases have version numbers 2.7.x. See the development page how to obtain the latest sources and support development.
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.
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).
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.
