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):

Install Packages / Released version

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.

Install from Source / Development version

You need the latest stable released FPC installed in order to compile the development version.

Download and install a compiler

Download and install the FPC package:

There are two development versions of the compiler: 2.2.x is stable version without new features - only bug fixes. And the unstable 2.3.x with lots of new features and bugs. The 2.2.0 version has a bug and can not be used to compile the 2.2.3 nor 2.3.1. You must download and install the 2.2.2. Some daily snapshots can be found here. Keep in mind that these are daily snapshots and that you can have bad luck and get a buggy version. The probability is about 1:30. So if the version is buggy try another day or use the released packages instead.

Download the sources via svn

The sources are kept in a version control system called subversion or short svn:

  • 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. A quite handy client, which integrates in Finder, is SCPlugin.

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 fpc

This will create a directory 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

Building fpc

[]$ make clean all
[]$ sudo make install

Then download lazarus

[]$ svn co lazarus

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/lazarus
[]$ svn up

Building lazarus

[]$ make clean all

Then start lazarus either via command line or by double click in the finder:


First Steps

The carbon interface is young and has some bugs. But gladfully if you know them you can work around them and get a productive IDE:

  • The carbon IDE looks somewhat nicer, although the autosizing does not work yet correctly and so some dialogs looks pretty bad until you enlarge them manually.
  • There is no optimal set of IDE shortcuts for the Mac yet, and so many features like help, identifier completion, toggle form/unit, compile, run, jump back do not work, because OS X itself uses those shortcuts. You must change the shortcuts in the editor options / keymappings. Beware, some key combos are not yet recognized and can give errors. At the moment it's recommended to only use Cmd-letter and Cmd-Shift-letter combinations.
  • The Alt key sometimes cease to functions. Just restart the IDE. It starts quite fast.
  • The blinking cursor vanish after popup menus and modal forms. Just switch to another page and back. Again: The normal page switching short cuts don't work, you may want to define some in the keymappings.
