Installing Lazarus on macOS

Installation

Apple Developer Tools

You need the Apple Developer tools. They are included on the original OSX installation CDs, or download at ADC (free registration required):

http://developer.apple.com/.

Install Packages

Download and install the three packages FPC, FPCSrc and Lazarus in this order. This is the easiest way to install Lazarus on Mac OS X. To get the current development version see below.

Free Pascal Compile

Free Pascal Compiler

Then download and install the Free Pascal Compiler (at least 2.2.0) from:

https://sourceforge.net/project/showfiles.php?group_id=89339

For Lazarus you need the FPC sources as well:

• 10.5 already installs svn. Users of earlier versions must install SVN for Mac OS X: A good package is provided by Martin Ott. You can also use fink. SVN clients with GUI (graphical user interface) are available from Versiontracker.

Create a directory, where you would like to put the sources. You don't need to be root to do this. Any normal user can do this. First create a directory for fpc

(e.g. /Users/username/freepascal)

then open a terminal and do the following:

[]$ svn co http://svn.freepascal.org/svn/fpc/trunk fpc

This will create a directories called 'fpc', which can be later used in the IDE. Hint: To download/update the latest changes you can simply do

[]$ cd /Users/username/freepascal/fpc
[]$ svn up

How to update fpc and Lazarus to the newest version

For 10.2 to 10.4

Install SVN for Mac OS X: A good package is provided by Martin Ott.

10.5 users don't need that because it already installs subversion by default via the XCodeTools package.
