Download and install release version of Lazarus

From SourceForge

Binary releases for various platforms are available via the Lazarus Sourceforge download area.

Specific for different platforms

Lazarus for Windows - use the Sourceforge link above.

Development versions from SVN

Getting SVN

You may download a SVN Client for Windows in http://tortoisesvn.tigris.org/ A SVN command line client is available from the official SVN website for many platforms.

On Linux, it is recommended to install subversion using the package management system offered by your distribution. For example:

sudo apt-get install subversion

Using SVN

Using the command line

To get Lazarus for the first time:

Open a terminal/command prompt, change to the directory you wish the Lazarus folder to be created in and type:

 svn co http://svn.freepascal.org/svn/lazarus/trunk lazarus

To update Lazarus sources:

Open a terminal/command prompt, change to the lazarus directory and type:

 svn update

For compiling see here.

Alternative URLs

Sometimes the URL of repository given above does not work, because between the svn server there is a http-proxy server. That server usually claims to be a 'transparent' proxy, but still doesn't pass your svn commands correctly to the svn.freepascal.org server.

The svn.freepascal.org server also listens on port 8080. Maybe the proxy doesn't interfere with http trafic on that port, so you can try:

svn co http://svn.freepascal.org:8080/svn/lazarus/trunk lazarus

The Lazarus svn repostory is mirrored on sourceforge with a delay of 15 minutes using fpsvnsync. The sourceforge repository uses the https protocol. Proxy servers usually don't interfere with that protocol. You can check out form sourceforge using the following command

svn co https://svn.sourceforge.net/svnroot/lazarus/trunk lazarus

The FPC and Lazarus svn repostories are also mirrored to svn2.freepascal.org. You can check out from svn2.freepascal.org with

svn co http://svn2.freepascal.org/svn/lazarus/trunk lazarus

If you own the proxy server, or are friends with the person who does, there are details of setting up a proxy to pass svn commands here: http://subversion.tigris.org/faq.html#proxy This contains an example for squid. Remember to set up the client to use the proxy ! (For TortoiseSVN, see settings/network)

Scripts

Lightning: Here is a windows batch script that takes care of checking out and updating Lazarus from SVN to a subdirectory and even basic error fixing, because i have no way of knowing where Lazarus is installed it cannot compile or copy the files to your working Lazarus instalation. Please save the script as getlaz.bat or some other name, however there is no warranty of any kind, use at your own risk, put it in a test directory first and make sure there is no subdirectory already called lazarus.

@echo off

Matthijs: In Linux I use a script (it is not very sophisticated, but does the trick) to download the latest SVN-version for Lazarus. Before I copy it here I'll explain my system. In my home-directory I have a special cvsroot-directory. In this directory I have a script for downloading Lazarus and other interesting projects. Lazarus is installed in /usr/share/lazarus. Before building a new version from SVN I make a backup, just in case the current svn is unstable. This is done by moving the /usr/share/lazarus directory to /usr/share/lazarus.bu To adapt the script to your system you only need to alter the constants defined at the start of the script. But without further ado, here is the script. But (big but) it is given without any guarantee. :) If things break you are on your own.

#!/bin/bash

# before you can use this script you have to checkout all files
# so first do a
# svn checkout http://svn.freepascal.org/svn/lazarus/trunk lazarus

#Define some directories
BASEDIR=/usr/share/
LAZCVSDIR=~/cvsroot/lazarus/
LAZDIR=/usr/share/lazarus/
LAZBACKUP=/usr/share/lazarus.bu

#Remove old backup if it exists
date +"%T %tStart"
if [ -d $LAZBACKUP ]
then 
  date +"%T %tRemoving old backup"
  rm $LAZBACKUP -fr
else
  date +"%T %tNo backup to remove"
fi

date +"%T %tCreating copy of lazarus dir"
cp -R $LAZDIR $LAZBACKUP

#Getting stuff from svn
date +"%T %tUpdate lazarus"
svn update lazarus > ~/cvs_update.log

#Copying cvs-files to our laz dir.
date +"%T %tcopying files"
cp -Rf $LAZCVSDIR $BASEDIR --reply=yes

#Make and building of lazarus
date +"%T %tmake lazarus" 
cd $LAZDIR
make > /dev/null
date +"%T %tmake the packages"
make idepkg > /dev/null
date +"%T %tFinished"

svn trunk version of fpc

Here are some hints how to install the development version of fpc (at the moment 2.5.1), which contains new features, bug fixes but is less stable and contains new bugs. The compiler is not included in the Lazarus SVN, but has its own FPC SVN. You must install first the latest released fpc. See here: Installing the Free Pascal Compiler.

Create a directory and download fpc from svn:

mkdir -p ~/freepascal
cd ~/freepascal
svn co http://svn.freepascal.org/svn/fpc/trunk fpc

This will take some time.

There are many ways to compile and install FPC. You can use plain make (see below), but it is recommended to build a fpc package for your distribution (.deb or .rpm file). A fpc package allows to easily uninstall, upgrade and downgrade it and a package makes sure that all files are installed at the common places. So if something goes wrong, other users know how to help you.

Building and installing the svn version of fpc

On command line, go to fpc source root directory, loaded from svn server (~/freepascal/fpc). Run:

 make all

It compiles the compiler in 3 cycles, first using the already installed compiler and then using the newly compiled compiler. After successful compilation, run:

 make install INSTALL_PREFIX=~

It install all needed files under your home directory. You can install to any other directory if needed. You just have to use the root account if the directory does not allow writing with your normal user account. Then create a file

 ~/.fpc.cfg

It is a hidden file (note the first dot). Enter the following contents to the file, replacing "/home/myself" with your actual home directory name (if you installed to another directory, use that instead).

 #include /etc/fpc.cfg
 -Fu/home/myself/lib/fpc/$fpcversion/units/$fpctarget
 -Fu/home/myself/lib/fpc/$fpcversion/units/$fpctarget/*
 -Fu/home/myself/lib/fpc/$fpcversion/units/$fpctarget/rtl

This allows installing any future fpc versions into PREFIX=~ without editing the config file.

Later when Lazarus is installed, you need to set its Environment -> Options -> Files. Assuming the paths given above:

 Compiler path = /home/myself/bin/fpc
 FPC source directory = /home/myself/freepascal/fpc

Building a fpc debian/ubuntu package from svn version of fpc

Important: This script does not create the official debian/ubuntu packages. It creates a fpc package that contains the compiler and all packages.

To build the package you need to install some packages:

sudo apt-get install libgpmg1-dev fakeroot libncurses5-dev build-essential

Go into your lazarus source directory. The directory must be writable.

cd ~/freepascal/lazarus/tools/install
./create_fpc_deb.sh fpc ~/freepascal/fpc

If you get an error about a missing file or tool you may have to install a missing package. If you get a compilation error your installed fpc is not the released compiler or you were unlucky and fetched a fpc svn reversion that contains a bug. Search help on the mailing list, forum or chat. If it ran through you now have a deb file, which you can install:

 sudo dpkg -i fpc_2.5.1-091121_i386.deb

The file name is different for you. The next step is to compile the lazarus svn with this new compiler and tell the IDE to use the directory /home/username/freepascal/fpc as FPC source directory.

If you have not yet downloaded the lazarus svn, do it now: Development versions from SVN. For example:

cd ~/freepascal
svn co http://svn.freepascal.org/svn/lazarus/trunk lazarus

This will take some time, continue with:

cd ~/freepascal/lazarus
make clean all

If this gives linker errors, you have to install some packages (build-essential, libgtk2.0-dev,libgdk-pixbuf-dev). Start the IDE:

cd ~/freepascal/lazarus
./lazarus

This is a minimal IDE without any extra packages. Now the IDE must be setup and can be built with packages:

Go to Environment / Options / Environment
Set lazarus directory to /home/username/freepascal/lazarus
Set FPC source directory to /home/username/freepascal/fpc
Click Ok to close the dialog
Tools / Configure Build Lazarus / Quick Build Options / Build IDE with packages
Click Build.
Restart the IDE
Now you have the latest and greatest IDE built with the latest and greatest FPC.

Development versions from Git

There is a Git mirror of the official SubVersion repository being maintained on GitHub. This mirror gets sync'ed every 15 minutes with the SubVersion repository. For more information on getting Git and cloning the Lazarus repository, follow this link: Git Mirrors. You can also use git directly with SubVersion server using git-svn link. See Lazarus git-svn for details.

Development versions from Mercurial

~~There is a Hg mirror of the official SubVersion repository being maintained on florianklaempfl.de.~~

This mirror does not exist any more. See the message from Florian Klämpfl.

Daily Snapshot method

If you don't want to use svn directly, you can try a daily snapshot. For a list of mirrors see the Lazarus Snapshots Downloads page.

Browse the Source Repository with a Web Browser

The contents of the SVN archive can also be browsed with your web-browser through this viewcvs interface.

Lazarus Distributions

There are some unofficial sites where you can find Lazarus and Free Pascal too:

You can get a Ubuntu LiveCD from Austrian University of Applied Sciences hosting

http://www.sigma-server.com/liveCD/Ubuntu-7.10-NTC-Lazarus.iso and md5sum file is here http://www.sigma-server.com/liveCD/Ubuntu-7.10-NTC-Lazarus.iso.md5.

Compiling and installing Lazarus

See Installing Lazarus - An installation guide.

Building from command-line

Lazarus is shipped with Makefile for gnu make util. (Be warn, if you're also have Codegear(or Borland) tools installed, it might conflict with gnu "make" util).

The tool allows you to compile the lazarus from command-line easily. You need to have fpc and fpc-packages installed and configured first.

To compile the goto Lazarus directory in your terminal and type

 make

This should rebuild LCL and Lazarus IDE (with basic packages installed).

Make targets

Following compiling targets can be specified for the make tool:

clean

The command will clean all compiled LCL and IDE units. Warning, this might make your project uncompilable (even though IDE still run, since binary is not deleted)

For example:

 make clean

bigide - the command rebuilds LCL and IDE with additional packages.

For example:

 make bigide

lcl - the command rebuild LCL only. IDE is left untouched. The command is very useful if you're making changes to LCL and need to test the changes on your project without breaking Lazarus. Rebuild LCL only is faster than rebuilding both LCL and IDE

For example:

 make lcl

components
packager/registration
ideintf
packager
bigidecomponents
ide
idepkg
idebig
bigide
starter - the command rebuilds startlazarus binary.
lazbuilder
tools
all
cleanide
purge
examples - the command rebuilds examples lazarus
install
lazbuild

If no target is specified LCL and IDE Lazarus (with basic set of components) is rebuilt.

Make parameters

There're also additional parameters, can be used for 'making' Lazarus.

OPT=%compiler_switches

the %compiler_switches is passed to each fpc call. The option is useful for specifying defines

For example:

 make bigide OPT="-dNoGdkPixBufLib -gw2"

makes LCL and ide with NoGdkPixBufLib defined and dwarf2 debug info.

LCL_PLATFORM=%platform

%platform is the target Widgetset. It can be win32,gtk,gtk2,qt,carbon or cocoa.

For example:

 make LCL_PLATFORM=gtk2

Rebuilds LCL and IDE for gtk2 widgetset

FPC=%compiler_path

%compiler_path is the path to a custom compiler binary you want to build the target with.
