Fpc pascal linux download

• FPC has gained several new features lately in trunk (which will not be in the upcoming FPC 3.2.0 release):
  • Multiple helper types can now be active at the same time
  • Support has been added for custom attributes
  • The compiler can now generate LLVM bitcode for select platforms (Darwin/x86-64, Linux/x86-64, Linux/AArch64, Linux/ARMHF)

  While FPC 3.2.0 will not have support for the above list, it will have its own collection of new features and fixes!

  Today FPC celebrates its 25th birthday !

  25 years have passed since 8 june 1993, and FPC still does not only exists, but is more alive and kicking than ever!

  Current Version

  Version 3.2.2 is the latest stable version of Free Pascal. Hit the download link and select a mirror close to you to download your copy. The development releases have version numbers 3.3.x . See the development page how to obtain the latest sources and support development.

  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

  For the 80×86 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.

  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.

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

  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.

  Installing the Free Pascal Compiler

  Contents

  Overview

  There are a number of ways to install the Free Pascal Compiler and its libraries on your system. The current version and trunk, and sometimes beta and release candidates, are available directly from the FPC website (tar, exe, rpm, dmg, pkg files). In addition, versions of FPC are provided (including rpm and deb files) from the Lazarus download site. Linux users can almost certainly find FPC in their distribution’s repositories but may find that it is outdated.

  It is possible to build FPC from source, typically each release needs to be built with the previous release. It is possible to install FPC in the application space (often requiring root or administrator access) or in a your own user space. These things depend on your particular operating system.

  There is an extensive discussion of how to install and build Free Pascal compilers available here http://www.stack.nl/

  marcov/buildfaq.pdf — it may be a little too detailed for some users, but it is very comprehensive.

  Linux

  FPC Binary Packages

  Note: You have a number of way to install FPC presented here, which one is best for you depends very much on what you are planning to do and if you need a very current version. If you are also planning on installing Lazarus, perhaps a quick look at Installing_Lazarus and Installing_Lazarus_on_Linux is a very good idea.

  With the recent release of FPC 3.2.0, only a few distributions will have the new FPC compiler in its repositories. You can do one of —

  If you use rpm packages, you can find FPC320 in https://sourceforge.net/projects/freepascal/files/Linux/3.2.0/ or more generally in https://www.freepascal.org/download.html You might install using a command like —

  FPC Tar Balls

  Another option is installing from a tar, an easy and possibly even more useful model. These tars are available for a wide range of Unix like systems. You need to download the appropriate binary tar for your OS and CPU and you may also need the source files, common for all OS/CPU. You install FPC this way in your own space, not as root.

  Here is a series of commands, not a script, that will install FPC on a 64 bit Linux system. It could be scripted but would would need sanity and error checking. Note that I like to install things like this in my $HOME/bin directory, if you prefer having it in $HOME, it is even easier, I am sure you can see the differences.

  Note: A tar install does not resolve dependencies, if they are not already present, first install binutils, make, gcc.

  Note: The second wget above assumes you are working with an amd64 (AMD or Intel) type machine, other platforms require a different tar ball. For example, for a Raspberry Pi, you would use —

  FPC sources

  The FPC source files are stored in a Subversion (SVN) repository (https://svn.freepascal.org/svn/fpc/trunk) and mirrored in a Git repository (git://github.com/graemeg/freepascal.git). The repository keeps track of all the changes by developers in the source tree. Once you have the sources, please see Installing from source under BSD/Linux for instructions on how to install them.

  Update from the source repository using SVN or Git

  The SVN or Git repository has been made accessible for everyone, with read-only access. This means that you can directly access the code, and you will have really the last-minute sources available. It is also a method which requires less bandwidth once you have done the first download (checkout in SVN lingo; clone in Git lingo).

  Getting the source

  First, you need to have an SVN or Git client installed. Use your package manager, install a tool like TortoiseSVN on Windows, or look at the Subversion web site or the Git webs site for more details and client downloads.

  Using command line svn: change directory (cd) to the parent directory of your development area, eg To retrieve the full source repository for the first time into an fpc subdirectory under your home directory, type:

  Note: FreeBSD includes the svnlite client in the base system which you can use instead of installing the full Subversion svn client.

  Using command line git: change directory (cd) to the parent directory of your development area, eg To retrieve the full source repository for the first time into an fpc subdirectory under your home directory, type:

  To update the sources which were downloaded (checked out/cloned) above:

  Getting a separate branch

  If the current trunk version is in a state of rapid change and unsuitable for much use unless you want to work on the compiler itself, you can stay on a version that is updated with fixes. To do this, you have to find out a stable branch that you want to track instead of the default trunk development version.

  The example below shows how you can track the fixes_3_2 version; of course replace as needed depending on what branch you want to track.

  This example keeps the fixes in another directory under your home directory — it wouldn’t make sense to put two versions of the source in one directory.

  Update as usual:

  Note: There is no Git repository for fixes_3_2.

  Documentation sources

  The documentation sources are in a separate repository called fpcdocs, so the command to get them is:

  If you want to learn more about subversion, read this excellent Subversion book which is also available online in different formats for free.

  For more information, see the Free Pascal website.

  Compiling the FPC source

  • First install the release FPC from rpm/deb or tar balls as described above.
  • Get FPC sources (trunk) as described above.
  • Make FPC sources with (execute in the source (trunk) directory)

  Decide about install/to/directory and also add options that you need.

  /.fpc.cfg or /etc/fpc.cfg. It either has to be valid for the trunk compiler as well or you have to move it to the ../etc directory above your compiler executable. E.g. if your compiler is in

  /software/fpc/3.2.0/bin), you have to move the fpc.cfg to

  /software/fpc/3.2.0/lib/fpc/etc.

• If you have no valid global fpc.cfg file, you have to create one in install/to/directory/lib/fpc/etc. For this run the following commands

FreeBSD

Note: If you wish to also install Lazarus, you can omit installing FPC with the steps below as the Lazarus port will install it for you. See Installing Lazarus on FreeBSD.

Installing from the ports collection

The FreeBSD ports collection has FPC v3.2.2 version in /usr/ports/lang/fpc. FPC is scattered over 105(!) packages. The FPC source is now installed by default; it previously needed to be copied and uncompressed from /usr/ports/distfiles/freepascal.

This must be done as root.

Also, you can install FPC and units from pkg binaries:

Once FPC is installed you can check if it’s working by simply running as a normal user:

which should produce output similar to this:

Installing from tar

Select the appropriate 32 bit/64 bit tar file based on your system. For x86_64 64-bit FreeBSD, download from x86_64. For i386 32-bit FreeBSD, download from i386.

To install Free Pascal from a terminal:

Replace the desired Free Pascal version (3.0.4, 3.2.0, 3.2.2 or 3.3.1) and architecture (x86_64 or i386) as required.

If you want to install the Free Pascal Compiler globally, for example in /usr/local, run the install.sh script as root. install.sh script uses bash shell syntax. If you get Bad substitution error, make sure you run script with bash.

If you are on FreeBSD 12 or newer, the default linker is the lld . This may cause problems if you have code that uses, for example, the cthreads unit as in the following program:

The executable generated for this program will cause a segmentation fault when run. To fix this issue, you need to install the GNU linker:

and add a symbolic-link from /usr/local/bin/ld.bfd to /bin/ld.bfd .

OpenBSD

Installing from tar

Select the appropriate 32 bit/64 bit tar file based on your system. For x86_64 64-bit OpenBSD, download from x86_64. For i386 32-bit OpenBSD, download from i386.

To install Free Pascal from a terminal:

Replace the desired Free Pascal version (3.0.4, 3.2.0 or 3.3.1) and architecture (x86_64 or i386) as required.

If you want to install the Free Pascal Compiler globally, for example in /usr/local, run the install.sh script as root. install.sh script uses bash shell syntax. If you get Bad subtitution error, make sure you run script with bash. OpenBSD uses ksh as default shell. You need to install bash manually.

Installing from source on BSD/Linux

Effectively, you need:

2. A starting (bootstrap) FPC compiler. An FPC release can always be built by the previously released FPC version, and FPC trunk can always be built by the current FPC release. You can download a bootstrap Free Pascal Compiler or use your distribution’s package management/software system to install one.

FPC build process:

• Fetch necessary files (starting compiler), FPC source file or source svn directory
• If using FPC source files: extract/de-tgz in work directory,
• Build: enter work/fpc/ and run:

• Install FPC. Again in work/fpc, run

• Create a symlink for default FPC source path:

• Set up fpc.cfg configuration file:

• Optionally test to see if ppcx64 -i (or whatever compiler your architecture uses) gives output, else give a warning that user needs to add $PREFIX/bin to the current path. Try to compile a program with ppcx64 -viwn , and see if that gives errors.

If you need fpcmake package lists, you need to generate or supply them yourself, (in the port, or in an extra archive) either way, do a dummy install to /tmp/pack and determine the files installed with

Windows

Installing an FPC release with the Windows installer

Warning: If you are intending to also install Lazarus using the official Windows installer which installs both FPC + Lazarus, please ignore these instructions and instead refer to Installing Lazarus on Windows to avoid having to resolve any resulting conflicts.

By far the easiest way to get a working installation of the Free Pascal Compiler is to download and run the appropriate self-extracting Windows installer from the official SourceForge repository for FPC 3.2.0 — this release contains the current versions of the Free Pascal Compiler and the Free Pascal libraries. The Windows installer packages install very easily, and should work ‘out-of-the-box’. You will be taken through a typical Windows installation wizard to install the FPC binaries and Free Pascal libraries:

• Choose an installation location for FPC (suggested C:\FPC\3.2.0)
• Choose installation type (recommended Full Installation)
• Choose file associations, configuration file creation etc
• Install
• View README

Installing from source

Installing from source with a command line Subversion (svn) client is not for novices, since you also need a working bootstrap compiler to be able to compile the Free Pascal Compiler from source. Instructions for obtaining a bootstrap compiler are included below.

Obtaining the source with a command line svn client

The easiest way to get the Free Pascal Compiler source is by using a Subversion (svn) client. The exact commands may vary between svn clients; the commands given below are for the command line Subversion client downloadable from SourceForge — win32svn.

Source for a release version of FPC

First create a directory in which you’d like to keep the source. Any normal user can do this. Create a directory for FPC (eg C:\Source) by typing the following at a command prompt:

Now type issue the following command at a command prompt:

Wait while the Subversion repository is downloaded to the fpc-3.2.0 directory in your newly created Source directory. This can take a while. have a look at the helpful Free Pascal Forums while you wait 🙂 You may also like to read the excellent How to use the Forum Wiki article which explains how to get answers to pesky questions quickly. New Forum users are always welcome.

Source for a non-release version of FPC

There are two current non-release branches of the Free Pascal Compiler: the development (trunk) branch and the Fixes 3.2.0 branch which includes additional fixes to the released 3.2.0 version. Developers, and those who like living on the bleeding edge and testing new features and fixes, will choose the development version; more normal users, who wish to use a stable branch with some additional fixes since the latest release version, will choose the Fixes branch. The instructions below cover both these branches.

If it does not already exist, create a directory in which you’d like to keep the FPC source (eg C:\Source). Any normal user can do this. Now type the following command at a command prompt:

For the Fixes branch of FPC 3.2.0

For the Development (trunk) branch of FPC

Hint: To update your local copy of the repository with subsequent changes, you need only do:

For the Fixes branch of FPC 3.2.0

For the Development (trunk) branch of FPC

Obtaining the source with the GUI TortoiseSVN client

The first thing you will probably need to do is download the GUI TortoiseSVN Subversion client from TortoiseSVN website Download file area if you do not already have it available.

After downloading the appropriate Windows installer and installing it, you are ready to begin. You will notice that TortoiseSVN has added a number of shortcuts to the File Explorer context menu so that you can work easily with svn without needing to use the command prompt.

Source for a release version of FPC

To download the latest release version Free Pascal Compiler source from the Subversion repository, first create the directory in which you’d like to keep the source. Any normal user can do this:

• Open File Explorer and navigate to «Local Disk C:»
• Choose Home > New folder in File Explorer and create a directory for the FPC source (eg C:\Source).
• Right click in File Explorer in your newly created directory and you should see an entry for «SVN Checkout. » in the context menu, choose this entry and you will be presented with a TortoiseSVN Checkout Dialog.
• Fill in the «URL of the Repository» field with this URL: https://svn.freepascal.org/svn/fpc/tags/release_3_2_0
• In the «Checkout directory» field add fpc-3.2.0 to the existing C:\Source\ in the field so you end up with C:\Source\fpc-3.2.0. This is the directory which will house your local copy of the source repository.
• Leave the other fields at their default and click OK.
• Now you will be presented with a new dialog which shows the progress of the checkout. wait while the Subversion repository is downloaded to the fpc-3.2.0 directory in your newly created Source directory. This can take a while. have a look at the helpful Free Pascal Forums while you wait 🙂 You may also like to read the excellent How to use the Forum Wiki article which explains how to get answers to pesky questions quickly. New Forum users are always welcome.

Source for a non-release version of FPC

There are two current non-release branches of the Free Pascal Compiler: the development (trunk) branch and the Fixes 3.2.0 branch which includes additional fixes to the released 3.2.0 version. Developers, and those who like living on the bleeding edge and testing new features and fixes, will choose the development version; more normal users, who wish to use a stable branch with some additional fixes since the latest release version, will choose the Fixes branch. The instructions below cover both these branches.

The instructions are the same as for a release version of the Free Pascal Compiler given above, except that you will need to replace the «URL of the Repository» and «Checkout directory» fields with the appropriate values set out below:

For the Fixes branch of FPC

For the Development (trunk) branch of FPC

Updating your local repository

To update your local copy of the repository with subsequent source changes:

• Open File Explorer, navigate to your C:\Source and right-click on the fpc-fixes-3.2.0 or fpc-trunk directory.
• You should see an entry for «TortoiseSVN», if you hover over it, another longer context menu will be presented from which you should choose «Clean up. «. In the Cleanup dialog, check both «Delete unversioned files and folders» and «Delete ignored files and folders».
• Now right-click on the fpc-fixes-3.2.0 or fpc-trunk directory again and you should see an entry for «SVN Update» in the context menu, choose this entry and you will be presented with a TortoiseSVN Update Dialog and the update will start without you needing to do anything else. When the update finishes, click OK to exit.

Obtaining a bootstrap compiler

To obtain a bootstrap Free Pascal Compiler, download the distribution package fpc-3.2.0.i386-win32.exe and run it — it is a self-extracting installer, so just follow the instructions to install it. The installer should set the PATH environment variable as appropriate.

Then restart windows.

Compiling the FPC source

Before you start

• The installation PREFIX in the instructions that follow is totally dependent on the directory in which you installed FPC. The Windows FPC installer uses a default location of C:\FPC and the FPC 3.2.0 release files are placed in C:\FPC\3.2.0. Since versions change relatively frequently, it is recommended that you just select and maintain a single PREFIX default location without any regard to FPC version numbers. A reasonable PREFIX to adopt is the one used by the Windows FPC installer (C:\FPC) but you must also make sure that the C:\FPC\bin\i386-win32\ directory is added to your path environment variable.

• Check that the make.exe which is found first in your path environment variable is the GNU one included with your bootstrap FPC compiler. If you have a recent version of Delphi installed, watch out for its version of make being earlier in your path. It does not understand the FPC Makefile and you will receive many errors if you try to use it. You can check this by opening a command prompt and typing make -v. The result should be (or very similar):

• If you need to change your path so that the correct make.exe is found, you can either do it temporarily or permanently.
  • To change it temporarily (it is in effect only until you close the current command prompt) to find make.exe in C:\FPC\3.2.0\bin\i386-win32, at a command prompt type:
    • At a command prompt, navigate to your local FPC source directory (eg C:\Source\fpc-3.2.0) by typing:
    • To overwrite an existing FPC installation in, for example, C:\FPC) type:
    • If you also need the cross-compiler to x86_64, type the following commands which will compile the cross-compiler and then install it:

    The cross-compiler to compile programs for Windows 64 bit may now be found here: C:\FPC\3.2.0\bin\i386-win32\ppcrossx64.

    macOS

    Warning: If you are intending to also install Lazarus using the official macOS installation packages which install both FPC + Lazarus, please ignore these instructions and instead refer to Installing Lazarus on macOS to avoid having to resolve any resulting FPC conflicts.

    Installing an FPC release from the official macOS packages

    Step 1: Download Xcode (optional)

    Xcode is a 12GB download which will take up 16GB of disk space. You only need to download and install the full Xcode development environment if you need:

    • the SDKs for iOS, iPadOS, watchOS and tvOS; or
    • to validate and upload apps to the Mac App Store; or
    • to notarise apps for distribution outside of the Mac App Store.

    Xcode 11.3.1 for use on macOS 10.14 Mojave must now be installed by downloading it from Apple Developer Connection (ADC), which requires free registration. Xcode 11.4.x for use on macOS 10.15 Catalina can be installed from the Mac App store. Note that you must first move any old Xcode versions from the Applications folder into the trash or rename the Xcode app (eg Xcode.app to Xcode_1014.app). You can select which version of Xcode to use with the command line utility xcode-select.

    The developer tools can be installed from the original macOS installation disks or a newer copy downloaded from the Apple Developer Connection (ADC), which requires free registration. Download the Xcode file, it will end up in your Downloads directory as a zip file. Click it. It is unarchived into your Downloads directory. You may be happy with it there but maybe not. Other users will see the path to it but be unable to use it. And it is untidy there. So I moved mine and then told xcode-select where it was moved to (in a terminal) —

    Step 2: Xcode Command Line Tools

    This is shown here as a separate step because it really is a separate step in addition to Step 1. Don’t confuse this with the internal Xcode command line tools that the Xcode GUI will tell you are already installed. FPC does not use those Xcode internal command line tools, so do the following (it is quick and easy)-

    For Big Sur 11.x, you only need to enter the first of the two commands above unless you have also installed the full Xcode package. If you have only installed the command line tools, you should omit entering the xcodebuild command.

    Step 3: Download FPC

    Download the Free Pascal Compiler (FPC) and FPC source from the Free Pascal website. When you arrive at the download page, select a mirror and then choose the correct version for your operating system.

    These installation packages are built by the FPC developers and track formal releases. As these installation packages are not code signed nor notarized by Apple, you need to either control-click on the installation package and choose «Open» or right-click on the installation package and choose «Open» in the contextual menu and confirm you want to install from an Unknown Developer.

    Installing from source

    There are two current non-release branches of the Free Pascal Compiler: the development (trunk) branch and the Fixes 3.2 branch which includes additional fixes to the released 3.2.2 version. Developers, and those who like living on the bleeding edge and testing new features and fixes, will choose the development version; more normal users, who wish to use a stable branch with some additional fixes since the latest release version, will choose the Fixes branch. The instructions below cover both these branches.

    The source code is kept in a version control system called git:

    • macOS 10.5 and higher already contain a command line git client if you have installed the Xcode command line utilities.
    • You also need the latest released Free Pascal Compiler version (3.2.2 as of August 2021) installed in order to be able to successfully compile the development (trunk) version.

    Note: When building a native aarch64 Free Pascal Compiler (ppca64) for an Apple Silicon M1 processor Mac, change the CPU_TARGET in the instructions below from x86_64 (Intel 64 bit) to aarch64 (ARM 64 bit — Apple Silicon M1) and change any reference to ppcx64 to ppca64

    FPC Trunk

    Note that since FPC trunk is by definition still under development, some of the features may still change before they end up in a release version.

    Create a directory where you would like to put the source (eg fpc_trunk in your home directory). You don’t need to be root to do this. Any normal user can do this. Open an Applications > Utilities > Terminal and do the following:

    This will create a directory called ‘fpc_trunk’ and download the FPC trunk source to it.

    To subsequently update your local source repository with the latest source changes you can simply do:

    To build and install FPC (the highlighted text should be all on one line):

    You will also need to update the links for the compiler in /usr/local/bin which will be pointing to the previous FPC version. For example:

    Note that you will need to build a new ppc386 compiler if you want to continue to compile 32 bit applications by replacing these lines (this may not be possible after Xcode 11.3.1 and macOS 10.14.6 Mojave because of Apple’s removal of 32 bit frameworks):

    with these two lines:

    FPC Fixes 3.2

    Create a directory where you would like to put the source (eg fpc_fixes32 in your home directory). You don’t need to be root to do this. Any normal user can do this. Open an Applications > Utilities > Terminal and do the following:

    This will create a directory called fpc_fixes32 and download the FPC source to it.

    To subsequently update your local copy of the repository source with the latest source changes you can simply do:

    To build and install FPC (the highlighted text should be all on one line):

    You will also need to update the links for the compiler in /usr/local/bin which will be pointing to the previous FPC version. For example:

    Note that you will need to build a new ppc386 compiler if you want to continue to compile 32 bit applications by replacing these lines (this may not be possible after Xcode 11.3.1 and macOS 10.14.6 Mojave because of Apple’s removal of 32 bit frameworks):

    Other installation options

    Testing the FPC Install

    You might like to try a simple and quick test of FPC at this stage. From the command line (Mac — Open an Application > Utilities > Terminal) and copy this very short program and save it as the file helloworld.pas:

    Now compile this simple code by typing this command and then pressing ↵ Enter :

    It should very quickly make an executable called, you guessed it, «helloworld». Run this executable by typing this command and then pressing ↵ Enter :

    If that worked, well done!

    Useful command-line switches for compiling from source

    • Significantly speed up the FPC source tree compilation
      • FPMAKEOPT=»-T x» (x = the number of CPU cores you have)
    • Reduce the number of times the compiler itself gets recompiled
      • NOWPOCYCLE=1
    • Add debug information and disable optimizations during compilation of the compiler/RTL
      • OPT=»-gl -O-«

    Installing cross compilers

    A cross compiler allows you to create binaries (executables) for a platform different from the platform being used for compilation. For example, working under macOS and creating executables for Win32, FreeBSD or Linux. For details on how to do this, see Cross Compiling.
