Download and install Lazarus release version
Binary releases for various platforms are available via the Lazarus Sourceforge download area.
For people who are blocked by SF, the Lazarus releases from Sourceforge are mirrored at:
- and later at (after some time for synchronization) http://michael-ep3.physik.uni-halle.de/Lazarus/releases/
- and http://mirrors.iwi.me/lazarus/
Specific for platform
Get Lazarus for Windows - use the Sourceforge link above.
Getting SVN client
TortoiseSVN Client is for Windows only. You may download it from http://tortoisesvn.tigris.org/.
This page demonstrates how to download and update Lazarus SVN source, but it can be used for FPC source in the same way.
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
Getting Lazarus SVN development version
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:
For compiling see here.
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 repository is mirrored on sourceforge with a delay of 3 minutes using svnsync. 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://lazarus.svn.sourceforge.net/svnroot/lazarus/trunk lazarus
The FPC and Lazarus svn repositories 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).
There are scripts for Windows and Linux to automate downloading and building Lazarus: Scripts for Lazarus
There is also a tool built with FPC/Lazarus that does this for you; see fpcup
Compiling and running Lazarus
Using the command-line
Lazarus is shipped with Makefile for gnu "make" utility.
The tool allows you to compile Lazarus from command-line easily. You need to have fpc and fpc-packages installed and configured first.
To compile go to Lazarus directory in your terminal and type
This should rebuild LCL and Lazarus IDE with basic packages installed. Another useful command is
which adds the same packages that the release version has.
Then you can run Lazarus from the same source directory with command "lazarus" (in Unix systems "./lazarus"). If the plan is to run many versions, you can use different configuration directories with --pcp option, thus "lazarus --pcp=configdir".
To see a list of available targets for make type make help. Note: "make help" exists since 1.0. Here is the output of "make help":
Main targets Without any target, target 'all' will be invoked. all build minimal IDE, lazbuild, startlazarus. clean deletes files that 'all' creates lazbuild build lazbuild and lcl with nogui widgetset bigide as all, except that the IDE is built with a lot of extra packages useride calls lazbuild to build an IDE with your active profile, requires lazbuild Sub targets registration build package FCL lazutils build package LazUtils, requires registration codetools build package CodeTools, requires lazutils lcl build package LCL, requires lazutils tools build lazres, svn2revisioninc, updatepofiles, lrstolfm, requires LCL with nogui widgetset ideintf build package IDEIntf, requires lcl basecomponents build synedit and lazcontrols for the LCL_PLATFORM, requires ideintf bigidecomponents build many extra packages for the LCL_PLATFORM, requires basecomponents starter build startlazarus, requires basecomponents examples build basic examples, requires basecomponents Note: There are more examples having their own directory Usage examples: Updating svn and build a minimal IDE, startlazarus and lazbuild: make clean svn up make clean all Note: You can start lazarus with 'startlazarus' Note: Use the IDE or lazbuild to compile your projects/packages. Updating svn and build an IDE with your last set of packages: make clean svn up make clean lazbuild useride Clean up: There is no command to clean up a svn repository completely, but you can use the following command under Linux/OS X: svn status | grep '\?' | sed -e 's/\? *//' | xargs rm -r
There're also additional parameters, can be used for 'making' Lazarus.
the %compiler_switches is passed to each fpc call. The option is useful for specifying defines
make bigide OPT="-dNoGdkPixBufLib -gw2"
makes LCL and ide with NoGdkPixBufLib defined and dwarf2 debug info.
%platform is the target widgetset. It can be win32,wince,gtk,gtk2,qt,carbon,cocoa,customdrawn.
Rebuilds LCL and IDE for gtk2 widgetset
%compiler_path is the path to a custom compiler binary you want to build the target with.
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.
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.
There are some unofficial sites where you can find Lazarus and Free Pascal too:
- FreeSparta is a commercial distribution of Lazarus for Windows.
- 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.
- The CodeTyphon distribution bundles Lazarus with additional packages and components.
- LiteZarus is a Lazarus distro intended for designing creating non-LCL projects.
- Lazarus is available on CDs and USB sticks from the Blaise Pascal Magazine store.
