Overview

For people who simply want to install Lazarus and start using it for programming, the easiest approach is to download and install a recent, reasonably stable binary release (such as a Linux ".rpm" package, a Windows ".exe" installer, or a Mac OS X ".dmg" package). You can read the sections under Linux or Windows entitled "fpc binaries" or the first paragraphs in the sections on installing Lazarus in Linux or Windows; most of the remaining information can be safely ignored.

For those who want to participate in the development of the compiler or the IDE, or for those who want the most up-to-date tools, an installation from source files is necessary, and much of the rest of this information is relevant.

Lazarus provides two main parts:

  • LCL - the Lazarus Component Library
  • IDE - the RAD tool

These in turn are dependent on:

  • FPC - the FreePascal compiler
  • FCL - the FreePascal Component library, containing most of the non-graphic components used by Lazarus

Lazarus System Requirements

  1. FreePascal compiler, packages, and sources. (*important*: of the same version/date)
  2. A supported widget tool-kit
    Win32
    The native Win32 API can be used
    Linux/xxxBSD
    GTK+ 1.2.x : Most Linux distributions and *BSDs already install the GTK+ 1.2.x libraries. You can also find them at http://www.gtk.org.
    You'll also want gdk-pixbuf, 0.13 or newer (preferably 0.18 or newer), which is also found in most recent distributions from the past 2 years. The source is available from ftp://ftp.gnome.org/pub/GNOME/sources/gdk-pixbuf/
    Mac OS X
    GTK+ 1.2.x : You need the Apple developer tools, X11, and GTK1.2. See Installing under Mac OS X below.
    GTK+ 2.x
    WARNING : The GTK2 interface is not yet complete and is only for testing purposes.
    It's found in most recent distributions. For the source see http://www.gtk.org.

The FAQ - Frequently Asked Questions file is available at http://www.lazarus.freepascal.org . Some of the questions can be found in the local file 'FAQ'.

The following sections describe how to get FreePascal and how to install Lazarus properly.

Installing The Free Pascal Compiler

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 is very comprehensive.

Lazarus requires fpc (FreePascal) version 2.0.2 or higher and it requires both the compiled fpc libs (binaries) and the fpc sources and of the same version.


Installing Free Pascal under Linux

FPC Binaries

The latest release of FreePascal, version 2.0.2, can be obtained from the FreePascal website (http://www.freepascal.org/download.html, then choose a mirror) or from sourceforge (http://sourceforge.net/projects/lazarus).

At the lazarus downloads section (http://www.lazarus.freepascal.org ) you can get the RPM of the Free Pascal compiler (compiler / linux) and its packages. If you don't have an RPM-based distribution, you can download and install the tarballs from http://www.freepascal.org. If you want to compile the binaries for yourself, see the BSD section.

Instructions:

WARNING: if you're not using RPMs (even if you plan to use alien) it's best to get latest stable fpc (2.0.2 as of now) and install Lazarus from source.

Start linux and login as ROOT.

Download lastest files from http://sourceforge.net/project/showfiles.php?group_id=89339. As example:

  • fpc-2.0.2-0.i386.rpm
  • fpcsrc-2.0.2-0.i386.rpm
  • lazarus-0.9.14-1.i386.rpm

and install them with:

  • rpm -Uvh fpc-2.0.2-0.i386.rpm
  • rpm -Uvh fpcsrc-2.0.2-0.i386.rpm
  • rpm -Uvh lazarus-0.9.14-1.i386.rpm

Debian users will need to resort to either alien (warning, it doesn't generate fpc.cfg) or the tarball install.

FPC Sources

Since the version 2.0 release, FPC has migrated to Subversion (SVN). There is currently no CVS mirror, so you will have to use SVN to get the FPC sources.

Download Daily Source Snapshot of Development Tree (version 2.1.x)

You can download today's development (v 2.1.x) sources in the form of a packed snapshot from the SVN source repository: these snapshots are updated on a daily basis, and reflect the state of the source repository. The files are kept at the site which has the SVN archive. Entire public sources archive of v2.1.x: fpc.zip (24 MB)

Download Daily Source Snapshot of Release Tree (version 2.0.x)

You can download today's development (v 2.0.x) sources that will lead to the next stable release in form of a packed snapshot from the SVN source repository: these snapshots are updated on a daily basis, and reflect the state of the source repository. The files are kept at the site which has the SVN archive. Entire public sources archive of v2.0.x: fpc.zip (24 MB)


Connect to Source Repository with SVN (replaces section on connection to CVS)

As an alternative to the daily zip files of the SVN sources, the SVN 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).

Development snapshots

How to do this? (You need to have SVN installed, of course. Look here for instructions on how to do that.)

Change Directory (cd) to the parent directory of your development area, eg

[]$ cd /home/username/FreePascal

To retrieve the full source repository, all publicly available modules, type

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

Normally, you should perform this step just once.

To update the sources which were downloaded (checkout) above

[]$svn update fpc


Fixes to 2.0.x

The fixes need a separate directory, create a separate directory 'fixes', enter it, and repeat the above checkout command with the URL http://svn.freepascal.org/svn/fpc/branches/fixes_2_0:

[]$ cd mysvn/fixes
[]$ svn checkout http://svn.freepascal.org/svn/fpc/branches/fixes_2_0 fpc

and to update:

[]$ svn update fpc

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

[]$ svn checkout http://svn.freepascal.org/svn/fpcdocs/trunk fpcdocs

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

For the curious: You have only read-only access, so don't try to commit anything :-)

For more information, see the FreePascal website

Installing Free Pascal under Windows

FPC Binaries for Windows

By far the easiest way to get a working installation of Free Pascal is to download the current binary Windows release of Lazarus from the SourceForge repository - the release contains the current versions of the FreePascal compiler and the FreePascal libraries as well as the lazarus IDE. If you want to install from sources, read on!

You can get the installer zip for fpc 2.0.2 at Free Pascal's download section http://www.freepascal.org/download.html, then choose a mirror). Installing from the sources -- see the next section to know how to get them -- is not for novices, since you need a starting compiler as well.

FPC Sources for Windows

<<<< See section above under FPC Sources for Linux, where the use of SVN is described >>>>

The easiest way to get the Free Pascal sources is via SVN; see the next section for more on that. You can also download the package as a whole -- see http://www.freepascal.org/develop.html for the daily snapshot of the 2.1.x release tree.

Windows FPC Sources via SVN ()

You will need to have a SVN client such as TortoiseSVN installed in order to perform the steps below. The exact commands vary between SVN clients; the ones given below are to be used under SVN home's client, which is available for download here.

First create a directory in which you'd like to put the sources. Any normal user can do this. Create a directory for fpc (e.g. C:\Source), then do the following at the command prompt:

 C:\Source> svn co http://svn.freepascal.org/svn/svn/trunk fpc

Hint: To download/update the latest changes you can simply do

 C:\> cd Source\FPC
 C:\Source\FPC> svn up

ToDo: Write me.

See: http://www.freepascal.org/down-win32.html . You can find a list of mirrors at http://www.freepascal.org/sdown.html. Download FPC as one big file, unzip it and run the install.exe.

Extending your PATH variable to the fpc directory:

  • Win98: Edit autoexec.bat and add the line: PATH=%PATH%;C:\pp\bin\bin\win32
  • WinXP/2k: My Computer (Right Click) -> Properties -> Advanced (Page) -> Enviroment Variables -> System Variables -> Edit "PATH", Add "C:\pp\bin\bin\win32" there.

Then restart windows.

ToDo: Explain how to download fpc sources and build the compiler

Installing Free Pascal under FreeBSD/auto

Latest FreeBSD ports collection has 2.0.2 (and soon 2.0.4) stable version in ports/lang/fpc2. All you have to do is install the port. If you want to use Lazarus you need to install "gtk" from ports first tho.

This can be done manualy as root.

[]# cd /usr/ports/lang/fpc2 && make install && make clean

Other possibility is to use portinstall.

[]# portinstall fpc2

Once fpc is installed you can check if it's working by simply running

[]$ fpc

There's one problem with FreeBSD and FPC however. The port installs all packages and FCL, but the latest glib and gtk from ports tree (which is required for Lazarus) has been renamed. This means that you'll get a "cannot find library -lglib" when linking Lazarus. You can fix this in one of two ways.

1. You can change the names in fpc sources and recompile [not recommended]
2. You can soft-link the new glib/gtk libnames to old ones.

2. can be done like this:

[]$ cd /usr/local/lib && ln -s libglib-12.so libglib12.so
[]$ cd /usr/X11R6/lib && ln -s libgtk-12.so libgtk12.so

Lazarus should compile and link after these changes.

Installing Free Pascal under BSD/manually

Effectively, you need

A file with all sources, or two (fpc and lazarus)

1. e.g. for fpc ftp://ftp.freepascal.org/fpc/dist/Linux/separate/sources.tar preferably an export (no CVS/ dirs). The above file misses this. 2. Lazarus source snapshot.

  • _any_ starting compiler from the 2.0.2 branch) You can do a check by parsing the output of ppc386 -i if it is 2.0.2 .. 2.1.x it is ok.
  • - dependant packages. (for FreeBSD that is gtk12, glib12 and gdk_pixbuf and GNU make, iconv and gettext)

FPC build:

1. (fetch) necessary files (FPC source, starting compiler) 2. (extract) Then de-tgz in work directory, 3. (build) enter work/fpc/ and run

 $MAKE all OPT='-gl -O3p3'  PP=/path/to/startingcompiler-name-ppc386
(/path/to/ can be omitted when ppc386 is in the path)
($MAKE is make on linux and gmake on BSD)

4. (install) then, again in work/fpc, run

$MAKE install PP=compiler/ppc386 PREFIX=$THEPREFIX
(THEPREFIX= usually is /usr/lcoal, but e.g. on NetBSD it is /usr/pkg for ports)
Create a symlink:
  ln -s $THEPREFIX/lib/fpc/2.0.2/ppc386 $THEPREFIX/bin/ppc386
     install sourceinstall PREFIX=$THEPREFIX

5. (configure) run compiler/utils/samplecfg $THEPREFIX/lib/fpc/2.0.1 $ETCDIR 6. (optional, test), see if ppc386 -i gives output, else give a warning that user need to add $PREFIX/bin to his current path. Try to compiler a program with -viwn, and see if that gives errors. Notes:

  • 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 find . >ll
  • $THEPREFIX and $ETCDIR should be user configurable. Otherwise local installs aren't possible.
  • BSDHIER=1 on all make commands forces BSD hierarchy conventions.

Installing Free Pascal under Mac OS X

You also need the Apple Developer tools, X11, and GTK 1.2:

Developer-tools: Are included on the original OSX installation CDs, or download at ADC (free registration required):

http://developer.apple.com/.

Apple X11: On a new system: choose "Customize" in the install dialog, check "X11".

On an already installed system:

MacOSX 10.3: download at:

http://www.apple.com/downloads/macosx/apple/x11formacosx.html

MacOSX 10.4: install X11 from the DVD.

GTK 1.2: Downloading the GTK packages and installing them properly can be a time consuming task. Therefore there are various package managers. One of them is fink:

Download fink from http://fink.sourceforge.net/download/index.php?phpLang=en; follow the install instructions.

In the Terminal, run

       sudo /sw/bin/apt-get install gdk-pixbuf gtk+ gtk+-data gtk+-shlibs gtk-doc gtk-engines

The X11 application is in /Applications/Utilities/X11. You can drag and drop it on the dock so you can start it with one click.

Tip: Most X11 programs, including Lazarus, expect to receive focus when the user clicks on a window. Under MacOSX this is deactivated. You can activate it for all X11 applications by typing in the terminal:

       defaults write com.apple.x11 wm_click_through -bool true
Free Pascal Compiler

Then download and install the Free Pascal Compiler (at least 2.0.2) from:

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

When compiling GTK-related software, you need to add two lines to the fpc.cfg file, to enable use of libraries:

-Fl/sw/lib
-Fl/usr/X11R6/lib

For Lazarus you need the FPC sources as well:

  • Install SVN for MacOS X: A good package is provided by Martin Ott.

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/svn/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

Installing Lazarus

Installing Lazarus under Linux

Installing using rpms

The easiest way to get a current working installation of Lazarus is to download the RPMs for FreePascal and Lazarus from the SourceForge repository.

You need to download the selected version of

  • the compiler (eg fpc-2.0.4-0.i586.rpm)
  • the pascal source library (eg fpc-src-2.0.4-0.i386.rpm)
  • the Lazarus package (eg lazarus-0.9.18-0.i386.rpm).

Here is an example of a script to install or update to ver.0.9.18 from a mirror, nchc. Save it as something like "InstallLazarus.sh", give it execute permission, and run after getting root privileges using su. Don't mind if you get "not installed" message.

 #!/bin/sh
 URL=http://nchc.dl.sourceforge.net/sourceforge/lazarus
 wget $URL/fpc-2.0.4-0.i586.rpm
 wget $URL/fpc-src-2.0.4-0.i386.rpm
 wget $URL/lazarus-0.9.18-0.i386.rpm
 rpm -ev lazarus
 rpm -ev fpc
 rpm -ev fpc-src
 rpm -ivh fpc-*
 rpm -ivh lazarus-*

Installing on Mandriva

Lazarus 0.9.18 on Mandriva 2007 (2007.0) (i386) (GTK-1)

Instalation in Mandriva is very easy. However, there are a few points to check as the installation proceeds. Here is a typical installation using the .tar modules:

- During the Mandriva instalation, select the "Gnome desktop" group. Although you will use lazarus in KDE or other desktop, this will install some GTK modules needed by the lazarus environment.

- Install the FPC 2.0.4 compiler using either the .rpm or .tar, modules. Using the .tar modules you would type: "sh install.sh" then RETURN many times. I do this in superuser mode.

- Install the compiler source code. just untar the file "fpc-src-2.0.4.source.tgz" in the folder /usr/local/src/fpc/ then rename the created folder "fpc" to "2.0.4" . When complete, you have the folder /usr/local/src/fpc/2.0.4/ that contains all the source code. The source code is only needed by lazarus editor, but you can recompile FPC and have an optimized version of the libraries, and show that everything is working well:

- If you want to compile FPC (optional), then go to the FPC source directory (/usr/local/src/fpc/2.0.4/) and type "./configure", "make clean","make all","make install","make clean". FPC is now installed. Check the content of "/etc/fpc.cfg". This file has to be modified when the make fails.

- Lazarus can be installed in user mode: just unzip/untar the file "lazarus-0.9.18.0.tar.gz" in your user directory. Then just type "make clean all" in the user mode. The last phase of the process (link) usually fails due to missing lbrary files:

- Check in the directory /usr/lib/ for the following symbolic links:

libglib.so -> libglib-1.2.so.0

libgtk.so -> libgtk-1.2.so.0.9.1

libgdk_pixbuf.so -> libgdkpixbuf.so.2.0.0

The file "libgdk_pixbuf.so.2.0.0" is included in the module "libgdk_pixbuf-2.0.22.0-10mdv2007.0.rpm" This file name is critical. I have tried using a very similar file name, but it failed. After all the links have been fixed, the "./lazarus" command should start the program!

- Go to the "environment/environment options" menu and change the "FPC source directory" to /user/local/src/fpc/2.0.4

- The last step is to fix the theme. The package "galaxy-gnome-1.0.4-3mdv2007.0" is available in the mandriva control center. Install it.

- The package "gtk-theme-switch-1.0.1-4mdv2007.0.i586.rpm" is available on the web! (strangely it did not show in the control center) Install it manually by typing "rpm -iv --test gtk-theme-switch-1.0.1-4mdv2007.0.i586.rpm" then retype the line without the "--test" in my case there was a warning message related to the signature. I decided to ignore it!

- in the user mode, type "switch", then chose "galaxy" theme.

the Lazarus / FPC tool is now installed!

Lazarus 0.9.20 on Mandriva 2007 32 bit
  • Write this urpmi command as root:
urpmi http://surfnet.dl.sourceforge.net/sourceforge/lazarus/lazarus-0.9.20-0.i386.rpm http://surfnet.dl.sourceforge.net/sourceforge/lazarus/fpc-2.0.4-0.i586.rpm http://surfnet.dl.sourceforge.net/sourceforge/lazarus/fpc-docs-2.0.4-0.i586.rpm http://surfnet.dl.sourceforge.net/sourceforge/lazarus/fpc-src-2.0.4-0.i386.rpm

It seems like Lazarus 0.9.20 depends on fpc 2.0.4, and Mandriva 2007 is shipped with fpc-2.1.1-0.2mdk.i586. To prevent your system to upgrade to fpc-2.1.1 or newer in the future, when you run commands as urpmi --auto-select, you can write fpc in /etc/urpmi/skip.list.

Lasaruz snapshot on Mandriva 2007 32 bit
urpmi $(for RPM in $(lynx --source http://michael-ep3.physik.uni-halle.de/Lazarus/ | grep i386.rpm | cut -d '"' -f 4-4) ; do echo -n http://michael-ep3.physik.uni-halle.de/Lazarus/$RPM ' '; done )
Installing Lazarus + fpc For Mandriva 2007 X86_64

This has worked for Mandriva 2007.0 X86_64 (AMD X2 4800+)

fpc-2.0.4-20061006.x86_64.rpm
fpc-src-2.0.4-20061006.x86_64.rpm
lazarus-0.9.19-20061006.x86_64.rpm
  • To install the current snapshot:
urpmi $(for RPM in $(lynx --source http://michael-ep3.physik.uni-halle.de/Lazarus/ | grep 64.rpm | cut -d '"' -f 4-4) ; do echo -n http://michael-ep3.physik.uni-halle.de/Lazarus/$RPM ' '; done )
  • Once the RPMs have been installed. Run lazarus for the first time. It will pop up a dialog complaining that the "/usr/bin/ppc386" and "/usr/lib/lazarus" are not valid. Accept ("OK") the alternate choices it suggests.
  • When compiling your first project, you may find that lazarus complains of missing libs (e.g. gdk, glib, etc.). Install the necessary libs as needed, I installed these (that I recall, YMMV):
glib-devel
lib64gtk+1.2-devel
lib64gtk+2.0_0-devel
lib64gdk-pixbuf2
lib64gdk-pixbuf2-devel

Installing on Suse

Installing Lazarus 0.9.18. For Suse 10.1 users

This have worked on SUSE10.0 and FC5.

Start Linux and login as "Root"

Free Pascal Compiler requires:
- Gnu binutils (gnu as, gnu ld, gnu make) - check it out with "YAST"

Download these binary files (RPM)

  • fpc-2.0.4-0.i586.rpm (yes i586 and not i386)
  • fpc-src-2.0.4-0.i386.rpm

install them opening a terminal session (mouse's rigth button -> Menu: Open in terminal)

  • rpm -Uvh fpc-2.0.4-0.i586.rpm
  • rpm -Uvh fpc-src-2.0.4-0.i386.rpm

Lazarus requires these components: 1) glib devel 2) gtk devel 3) gdk-pixbuf-devel 4) gtk+-devel.
The last component seems does not work with Suse, then once we have installed the first three components we can force installation with -nodeps option:

  • rpm -Uvh --nodeps lazarus-0.9.18-0.i386.rpm

Installing from source

If you prefer to install from source and compile the files yourself, follow these instructions. Because the whole lazarus stuff is installed into one directory, uninstall is very easy and you don't need to be root to install lazarus. You can get tgz files for fpc, fpcsrc and lazarus from the downloads section or you can download it directly via svn.

Here is an example of installing 0.9.18 to Ubuntu 6.06. If you understand Linux commands and bash script, you can get what steps are needed. Just copy the script (change the version number when new version has been released), paste it into a text editor, and save it as something like "install_lazarus.sh". Give it execute permission, and run it in a console. Note: In this example, fpc is installed in /opt. So when prompted 'Install prefix', enter '/opt/fpc'.

 #!/bin/sh
 
 #installing required packages
 sudo apt-get install build-essential
 sudo apt-get install libgtk2.0-dev
 sudo apt-get install libgdk-pixbuf-dev
 
 #installing FreePascal source

 sudo sh install.sh

 PATH=/opt/fpc/bin:"${PATH}"
 sudo chmod -R 777 lazarus
 cd lazarus
 make clean all
 ./lazarus

Note: You have to manually set fpc-src path in the Environmental Options.

Downloading Lazarus SVN

The lazarus repository has moved from cvs to svn (Subversion). SVN provides an easy way to update your sources by only downloading the changes. This is the recommended way and saves you a lot of time. A connection to the internet is needed for this: you don't need to be root. Lazarus does not need any special permissions, neither during installation nor at runtime.

With the move we also changed the directory layout of the lazarus sources. The main difference is that all ide sources are moved from the root to a separate ide subdir. As anybody might understand, this has an impact on the Makefiles, the searchpaths etc. We are in progress of fixing things, so if something doesn't work, please let us know.

Now the most important thing.... getting the sources
 []$ svn checkout http://svn.freepascal.org/svn/lazarus/trunk/ lazarus

(or any other dir where you want to place your sources)

On subsequent occasions, to update simply type

 []$ svn update lazarus

For more information on Subversion, see: http://subversion.tigris.org/

Note: the CVS is still accessable, but it frozen. This means that no new updates are comitted.

Compiling and running

Whether you checkout from cvs or svn, the next step is:

compile lazarus
[]$ cd lazarus
[]$ make  (gmake on BSD)


If fpc is installed correctly, the compilation should work without problems. If not, see FAQ.

Start lazarus
[]$ ./lazarus

The IDE should start. If you started lazarus in a terminal, you can see some notes about missing settings. This is normal at first start. The IDE automatically tries to find out where the freepascal compiler and its sources are installed by searching in the most common directories.

Check the paths
Use the IDE menu to go to
Environment -> Environment Options -> Files

The 'FPC Source directory' should point to your fpc source directory. This directory normally ends with /fpc/ or /fpcsrc/ (e.g. /usr/src/fpcsrc or /home/username/freepascal/fpc) and contains directories like 'compiler', 'docs', 'fcl', 'rtl' and 'packages'.

ToDo: explain the other paths

Hint

To update lazarus you can use

[]$ svn update lazarus

then for either update pathway:

[]$ make clean all   (gmake on BSD)

This will rebuild lazarus and create an IDE without lazarus packages. To link your installed packages do after the above:

[]$ make idepkg

Installing Lazarus under Debian GNU/Linux

There are preliminary Debian packages for lazarus available for download. They are not the latest versions, however. Make sure you read /usr/share/doc/lazarus/README.Debian carefully before you start using it. Feedback is needed and appreciated; please send your comments to Carlos Laviola <claviola@debian.org>.

Note that for a fully working Lazarus install, no older or incompatible versions of, for example, the fpc source or fpc compiler must be installed. Remove them by typing

 dpkg -r <package name>   

without .deb extension. And then install the newest versions as described.

Another way to install Lazarus under Debian

Added by User:Kirkpatc.

Simple Lazarus Installation in Debian

(assume new Debian installation, without development libraries loaded)

From sourceforge repository, download latest fpc, fpclib and lazarus releases; follow links from http://lazarus.freepascal.org, click the "downloads" button on the left, then click on "binaries" then "linux" then "Current Lazarus RPM". This will bring you to

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

then download the following files (or more recent, if available)

  • fpc-2.0.0-0.i586.rpm
  • fpcsrc-2.0.0-0.i386.rpm
  • lazarus-0.9.8-fpc_2.0.0_0.i386.rpm

cd to the directory where these files are stored, then become root (su) and type:

alien -c fpc*     //this will convert both the fpc and fpcsrc files to debian format and convert the install scripts
alien -c laz*

then install the generated Debian (.deb) packages by (as root):

dpkg -i fpc*.deb laz*.deb

or use kpackage or a similar utility to install the generated fpc, fpcsrc and lazarus .deb files.

And if you do not have alien type:

apt-get install alien 

Please note that, on Linux distributions like Ubuntu, you'll have to add 'sudo' in front of all commands. In Ubuntu previous command would be

sudo apt-get install alien

You need to produce a configuration file, which will reside in /etc/fpc.cfg. Still as root, cd to the main fpc directory /usr/lib/fpc/2.0.0 and then type

sh ./samplecfg /usr/lib/fpc/2.0.0 /etc

Check the contents of your new configuration file (cat /etc/fpc.cfg) and make any changes you want using vi or another text editor. Also make sure that there are no old configuration files in for example your home directory (~/.fpc.cfg).

You need to install the development packages of the GTK and pixbuf libraries, so

apt-get install libgtk2.0-dev
apt-get install libgdk-pixbuf-dev

Then you should be ready to start programming!

Installing Lazarus under Mac OS X

Works pretty much the same as under Linux. But you first need to install the Apple developer tools, X11, and GTK 1.2.

Easy-to-install snapshots are also from the snaphot servers.

If you install all 3 .dmg snapshot files, this also installs the FPC compiler and the FPC and Lazarus source too. If you only need to run Lazarus to develop and compile your own apps, you don't need to install the FPC and Lazarus sources as described above. If you need to rebuild Lazarus or want to help with its development, then you should to install the Lazarus source to a folder where you have read-write permission, as described above.

If you want to experiment and develop the Carbon widgetset interface, look at Carbon Interface.

There are at least two ways to start Lazarus under OS X:

Start X11. In the terminal window, type:

cd /usr/local/share/lazarus
./lazarus

You can also run Lazarus from the X11 menu. Choose Applications | Customize, click Add Item, then under Name enter Lazarus and under Command enter:

open -a /usr/local/share/lazarus/lazarus

Click Done. Now you can start Lazarus by choosing Applications | Lazarus.

Installing Lazarus under Windows

The current releases of the Windows Lazarus binary packages install very easily, and should work 'out-of-the-box'.

It is even possible to install the whole Lazarus/FPC package on a portable USB drive (capacity at least 256 MB), for use in environments where you are not allowed to install software on your Windows workstation or where you haven't got administrator privileges. You do have to be a little careful about adjusting the paths in the compiler and environment options and the fpc.cfg file. It may also be necessary to keep the directory for test compilation on your portable drive. << DOES ANYONE KNOW HOW TO SET UP RELATIVE PATHS IN THESE TAGS AND FILES, SO THAT THE ADDRESSING WORKS WHEN YOU MOVE THE USB DEVICE TO ANOTHER MACHINE WHERE IT HAS A DIFFERENT DRIVE LETTER? >>

The binary package is available for Linux and Windows from

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

Download the latest release (currently Lazarus-0.9.15-20060415-win32.exe) and launch the application. You will be taken through a typical Windows installation, in which the FPC compiler and source libraries are installed within the same directory structure as Lazarus, and the IDE should launch and operate without significant problems, provided you have uninstalled any previous version of Lazarus and/or FPC (often found in the C:\pp directory).

You can also use a Lazarus Snapshot. For download locations see Lazarus Snapshots Downloads.

Installing from source

If you prefer to install from sources, then follow these instructions (Thanks to Joe for the initial Step-by-step description)

You have to download the lazarus source from one of the snapshots servers.

Then unzip it to c:\lazarus for example. You have to install at least fpc-2.0.2, but a fpc-2.0.3 or fpc 2.1.1 snapshot is also possible. It compiles for me, and lazarus.exe works. The path to my fpc is: c:\pp\bin\win32. In this directory you can find a lot of exe (make, grep, ppc386, and so on).

Open a command line. Start->Run...>command or choose MS-DOS icon.

Type:

cd c:\lazarus
set path=c:\pp\bin\win32;c:\lazarus  //of course change the first to
                                     //the path of yours
windres -i lazarus.rc -o lazarus.res
make

If you are lucky then you can type: lazarus.exe. The source editor, dialogs and the property editor work, but not perfectly... Look and you will see.

You can compile examples also:

cd examples
make

If you extracted lazarus to another drive, eg.: d:\lazarus. It can happen that you need the gnu utility to make it. If you have it, you can take its path to set path=...;<gmakepath> but it is simpler not to choose drive d:\

That's all.

Additional experiences and advice on installing FPC and Lazarus

On linux, getting Lazarus to work can be complicated. If you have already installed earlier versions of FPC and/or Lazarus, you have to take great care that the PATHS are adjusted so that only your new versions are called.

Pitfalls that I have experienced in various attempts with SuSE linux include:

The rpm versions often install FPC in /bin or /usr/bin, with the libraries in /lib or /usr/lib.

If you perform a make install on a source version or use a .tar.gz, the compiler is usually installed in /usr/local/bin with the libraries in /usr/local/lib.

So if earlier versions have been installed from rpm, make sure all links are changed to reflect the directory structure of your new compiler. The place to make the changes is in /etc/fpc.cfg ; make sure there are no remnant configuration files in your home directory or in your FPC download directory. Typically they are found in ~/.fpc.cfg

Make sure the links in /etc/fpc.cfg point to the correct versions of the libraries (particularly if you have older versions still lurking around).

In /usr/local/bin or /usr/bin there is a file called fpc ; this is the executable that is called when you invoke the compiler. One of the first things it does is to open ppc386 in the same directory. This has to be the same version as the fpc file, or can be a link pointing to the true ppc386 in some other directory (such as a library directory, or the fpc directory in your own development space); be sure to update your link if you install a newer version of the compiler.

Try running the compiler from the command line using one of the simple example programs or one which you wrote yourself.

Turning to Lazarus:

If you use a downloaded snapshot (.tar.gz) or get the source from CVS, enter your lazarus directory and type

make
./lazarus 

and hopefully the IDE should load. There may be a message saying it can't find the sources; if so, go to the menu at the top and select Environment -> Environment options and insert the name of the directory where you expect to find your lazarus files (eg ~/FreePascal/lazarus), your compiler (eg /usr/local/bin/ppc386), the FreePascal source directory (eg /usr/local/lib/fpc/$version/fpc or a directory in your own space eg ~/FreePascal/fpc). Then close the dialog and start programming.

You may find further problems when you start programming or compiling; most of these will be related to PATH selection.

Many of the difficulties are dealt with in the Lazarus FAQ, found either on this WiKi site, or a more complete list on the main Lazarus site

http://www.lazarus.freepascal.org/modules.php?op=modload&name=FAQ&file=index

From the top menu select Run -> Compiler Options (or Project -> Compiler Options in more recent releases of Lazarus) and select the Paths tab on the resulting dialog. There are several boxes for entry of paths for Unit files, Include files, Other source files, Libraries etc. For each of these, it is worth pressing the ... (ellipsis) button on the right, and you will be given a blank window for inserting path information, and a lower window giving some suggestions. Select as many as you like (or ALL!) and press the ADD button to transfer the selections to the upper window. When your selection is complete, press OK and move on to the next box. If you know of other paths which need to be followed, press the Browse button associated with each box, and insert the additional paths.

When you think you have got your paths right, try to compile your application. If there are further path-related errors ('can't find unit .......') then go back and check your paths, both in /etc/fpc.cfg and in your Run -> Compiler Options dialog (or Project -> Compiler Options depending on your version).

Once you have got the environment and PATHS correct, it is worth saving the settings to a file, otherwise you will have to go through this process for each new project. In the Run -> Compiler options dialog there is a Load/Save button; select this and then save the setings to the filename of your choice: mine is ~/FreePascal/default.cfg. Then each time I start a new project, I can go to the Run -> Compiler Options dialog (or Project -> Compiler Options), select Load/Save, and load my default.cfg file to the new project. You can, of course, modify the options for each new project if you so desire.

Installing Lazarus under BSD

FreeBSD 4.10+

As the text above says, you must have GTK+ 1.2 installed. I did not, so I installed that first as root:

> pkg_add -r gtk
> pkg_add -r gdk-pixbuf
> cd /path-to-lazarus
> gmake
> ./startlazarus

If you get the messages about missing source files, go to [menu bar >> Environment >> Environment Options >> Files Tab: FPC source library] and enter the directory of the FPC source files. I got them from SVN as described above.

Good luck, that worked for me. --Jrmarino 21:29, 4 Jan 2006 (CET)

This works on 6.0 too. There were 2 potential problems tho.

1. After start, lazarus source editor seemed to have some broken font. This is due to missing courier. Fix is simple, go to editor options and chose another font (clean works for me).

2. Unlike on Linux you MUST specify path to GMAKE (not make) in environment options if you wish to use packages and lazarus self-build features.

PC-BSD 1.0rc1+

You can install Lazarus on PB-BSD by simply downloading the Lazarus PBI from PBI Dir

Note that you must install glib* port from /usr/port/devel/glib* or glib packages by pkg_add -r glib12 glib20. I will fix this in new PBI releases.
