Resumen

Para aquellos que simplemente quieran instalar Lazarus y empezar a usarlo para programar, la forma más sencilla es descargar e instalar una versión binaria reciente y razonablemente estable (como un paquete ".rpm" en Linux o un paquete ".exe" en Windows). Puede leer las secciones que hay a continuación para Linux o Windows llamadas "binarios de fpc" o los primeros párrafos de las secciones sobre instalación de Lazrus en Linux o Windows; la mayor parte del resto de la información puede ignorarla.

Quienes deseen participar en el desarrollo del compilador o del IDE, o para quienes deseen las herramientas más actualizadas, necesitarán una instalación de archivos fuente, y la mayor parte del resto de esta información es relevante.


Lazarus cuenta con dos elementos principales:

  • LCL - Lazarus Component Library (Librería de componentes de Lazarus)
  • IDE - la herramienta de RAD (Rapid Application Development=Desarrollo rápido de aplicaciones)

Éstos a su vez dependen de:

  • FPC - el compilador de FreePascal
  • FCL - la librería de componentes de FreePascal, que contiene la mayor parte de los componentes no gráficos que usa Lazarus.


Requisitos del sistema para Lazarus

  1. El compilador, los paquetes, y las fuentes de FreePascal (* importante *: de la misma versión y fecha)
  2. Soporte del juego de herramientas Widget
    Win32
    Se puede utilizar el API nativo de Win32
    Linux/xxxBSD
    GTK+ 1.2.x: La mayoría de las distribuciones de Linux y *BSDs ya instalan las librerías de GTK+ 1.2.x. Puede también encontrarlos en http://www.gtk.org. También necesitará el gdk-pixbuf, 0.13 o posterior (preferiblemente 0.18 o posterior), que también se encuentra en la mayoría de las distribuciones recientes desde hace 2 años. La fuente está disponible de ftp://ftp.gnome.org/pub/GNOME/sources/gdk-pixbuf/
  3. :;Mac OS X: GTK+ 1.2.x: Necesita las herramientas de desarrollador de Apple, X11 y GTK1.2. Vea debajo Instalación en Mac OS X.
    GTK+ 2.x
    ADVERTENCIA: El interfaz GTK2 no está todavía completo y solamente para pruebas.

Se encuentra en la mayoría de las distribuciones recientes. Para la fuente vea http://www.gtk.org.

El FAQ - El archivo con preguntas realizadas a menudo está disponible en http://www.lazarus.freepascal.org. Algunas de las preguntas se pueden encontrar en el archivo local ' FAQ '. Las secciones siguientes describirán cómo conseguir FreePascal y cómo instalar Lazarus correctamente.

Instalación del compilador de Free Pascal

Hay un amplio debate sobre como instalar y construir compiladores de Free Pascal disponible en http://www.stack.nl/~marcov/buildfaq.pdf - quizá con demasiados detalles para algunos usuarios, pero fácil de comprender.

Lazarus necesita la versión de fpc (FreePascal) 1.9.x y tanto los binarios de fpc compilados como las fuentes de fpc, y ambas de la misma versión. La versión de fpc 1.0.6 tiene demasiados errores y la 1.0.10 tiene problemas al abrir formularios creados con la versión 1.9.x. Ha aparecido la versión 2.0.0 y es el compilador preferido (fpc-2.0.0).


Instalación de Free Pascal en Linux

Binarios de FPC

La última versión de FreePascal, la 2.0.1, se puede obtener desde el sitio web de FreePascal (http://www.freepascal.org/download.html, elija lugar desde donde descargar) o desde sourceforge (http://sourceforge.net/projects/lazarus).

En la sección de descargas de lazarus (http://www.lazarus.freepascal.org ) puede obtener los archivos RPM del compilador de Free Pascal (compilador / Linux) y sus paquetes. Si no tiene una distribución con sistema de archivos RPM, puede descargar e instalar los archivos tar desde http://www.freepascal.org. Si desea compilar los binarios usted mismo, vea la sección sobre BSD.

Instrucciones:

Descargue los últimos archivos desde http://sourceforge.net/project/showfiles.php?group_id=89339. Por ejemplo:

  • fpc-2.0.1-050923.i386.rpm
  • fpcsrc-2.0.1-050923.i386.rpm
  • lazarus-0.9.10-0.i386.rpm

e instálelos con:

  • rpm -Uvh fpc-2.0.1-050923.i386.rpm
  • rpm -Uvh fpcsrc-2.0.1-050923.i386.rpm
  • rpm -Uvh lazarus-0.9.10-0.i386.rpm

A diario se pueden descargar paquetes actualizados para Debian desde http://cYcnus.de/deb/. En la actualidad, contiene solamente los componentes de fpc compilados, pero no sus fuentes, lo que necesitarían la mayoría de los programadores de Lazarus.

Fuentes de FPC

Desde la versión 2.0, FPC no usa ya CVS, sino que ha migrado a Subversion (SVN). Por ahora, no hay mirror CVS, así que tiene que usar SVN para obtener las fuentes de FPC.

Descarga diaria de la instantánea de fuentes del árbol de desarrollo (version 2.1.x)

Puede descargar el desarrollo de las fuentes actual (v 2.1.x) en forma de una instantánea empaquetada del repositorio de fuentes SVN: estas instantáneas se actualizan a diario, y reflejan el estado del repositorio de fuentes. Los ficheros se mantienen en el sitio web que tiene el archivo SVN. Archivo de fuentes públicas completo de v2.1.x: fpc.zip (24 MB)

Descarga diaria de la instantánea del árbol de la edición (version 2.0.x)

Puede descarga el desarrollo de las fuentes actual (v 2.0.x) que llevará a la próxima edición estabale en forma de una instantánea empaquetada desde el repositorio de fuentes SVN: estas instantáneasa se actualizan a diario, y reflejan el estado del repositorio de fuentes. Los ficheros se mantienen en el sitio web que tiene el archivo SVN.

Archivo de fuentes públicas completo de v2.0.x: fpc.zip (24 MB)


Conectar un repositorio de fuentes con SVN (sustituye a la sección sobre conexión con CVS)

Como alternativa a los archivos zip diarios de las fuentes de SVN, el repositorio SVN se ha hecho accesible para cualquiera, con acceso de sólo lectura. Esto significa que puede acceder directamente al código, y tendrá verdaderamente a su disposición las fuentes de última hora. Es también un método que requiere menos ancho de banda una vez que ha hecho la primera descarga ( It is also a method which requires less bandwidth once you have done the first download (checkout en el lenguaje de SVN).

Instantáneas del desarrollo

¿Cómo se hace esto? (Necesita tener instalado SVN, claro. Busque en here las instrucciones sobre como se hace.)

Cambie de carpeta (cd) a la carpeta superior de su zona de desarrollo, por ejemplo 

[]$ cd /home/username/FreePascal

Para recibir el repositorio de fuentes completo, todos los módulos disponibles públicamente, teclee 

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

Normalmente, ejecutaría este paso sólo una vez.

Para actualizar las fuentes que se descargaron (checkout) anteriormente 

[]$svn update fpc


Fixes para 2.0.x

Los fixes necesitan una carpeta aparte, cree una carpeta aparte 'fixes', acceda a ella, y repita el comando checkout citado anteriormente con la 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

y para actualizar: 

[]$ svn update fpc

Las fuentes de documentos están en un repositorio aparte llamado fpcdocs, por lo que el comando para obtenerlos es 

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

Si quiere aprender más acerca de Subversion, lea este excelente Subversion book que también está disponible gratis en línea en diferentes formatos.

Para los curiosos: Se tiene acceso de sólo lectura, así que no intente hacer nada raro :-)

Instalación de Free Pascal en Windows

Binarios de FPC para Windows

La manera, en gran medida más fácil, de conseguir una instalación que funcione de Free Pascal es descargar la versión actual del binario Windows de Lazarus del repositorio de SourceForge - la edición contiene las versiones actuales del compilador de FreePascal y de las librería de FreePascal así como el IDE de Lazarus. ¡Si quiere instalar desde fuentes, continúe leyendo!

Puede conseguir el instalador zip para fpc 2.0.0 en la sección de descargas de Free Pascal http://www.freepascal.org/download.html , entonces elige un espejo). Instalación de las fuentes -- vea la sección siguiente para saber cómo conseguirlas -- no es para principiantes, puesto que necesita un compilador de inicio también. You can get the installer zip for fpc 2.0.0 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.

Fuentes de FPC para Windows

<<<< Vea la sección FPC Sources para Linux, donde se describe el uso de SVN >>>>

La manera más fácil de conseguir las fuentes de Free Pascal es vía CVS; vea la sección siguiente para más detalles. También puede descargar el paquete en su totalidad -- vea http://www.freepascal.org/develop.html para la instantánea diaria del árbol de la edición 2.1.x.

Fuentes de FPC para Windows mediante CVS ()

Necesitará tener un cliente de CVS como TortoiseCVS o WinCVS instalado para realizar los pasos indicados más abajo. Los comandos exactos varían entre los clientes de CVS; los que aparecen abajo deben ser utilizados bajo el cliente propio de CVS, que está disponible para la descarga aquí.

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> set CVSROOT=:pserver:cvs@cvs.freepascal.org:/FPC/CVS
 C:\Source> cvs login      // password is 'cvs' without the commas
 C:\source> cvs -z3 co fpc // This will create a directory fpc, which can be later used in the IDE.

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

 C:\> cd Source\FPC
 C:\Source\FPC> cvs -z3 update -dP

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

Instalación de Free Pascal en BSD/manualmente

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 1.9 branch) You can do a check by parsing the output of ppc386 -i if it is 1.9.3 .. 2.0.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/2.0.1/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.

Instalación de Free Pascal en Mac OS X

You need the Apple Developer-tools, X11, gtk1.2:

Downloading 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.

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 fresh system: choose "Customize" in the install-dialogue, check "X11".

On an already installed system: download at

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

In the Terminal, run 

       sudo fink install gdk-pixbuf gtk+ gtk+-data gtk+-shlibs gtk-doc gtkglarea gtk-engines

The X11-Application is in /Applications/Utilities/X11.

Hint: Most X11 programs, including lazarus expect to receive focus, when the users 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 1.9.5 from 16th August 2004) 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 (obsolete: use svn): 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: 

[]$ bash
[]$ export CVSROOT=:pserver:cvs@cvs.freepascal.org:/FPC/CVS
[]$ cvs login

password is 'cvs' without the 'quotes' 

[]$ cvs -z3 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
[]$ cvs -z3 update -dP

Instalación de Lazarus

Instalación de Lazarus en Linux

Instalación usando 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-1.9.5-041207.i386.rpm)
  • the pascal source library (eg fpcsrc-1.9.5-041207.i386.rpm)
  • the Lazarus package (eg lazarus-0.9.2.4-fpc_1.9.5_041207.i386.rpm).

You then issue the following commands (you need to have root privileges - use su or sudo) 

rpm -Uvh fpc-1.9.5-041207.i386.rpm
rpm -Uvh fpcsrc-1.9.5-041207.i386.rpm
rpm -Uvh lazarus-0.9.2.4-fpc_1.9.5_041207.i386.rpm

Instalación desde archivo fuente

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.

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.

Compilando y ejecuntado

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

Instalando Lazarus en Debian GNU/Linux

There are preliminary Debian packages for lazarus available for download. 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>.

Another (?easier) 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 fpc*     //this will convert both the fpc and fpcsrc files to debian format
alien 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.

Note, if you do not have alien type: 

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 need to install first the apple developer tools and X11.

Snapshots are available at http://www.de.freepascal.org/lazarus/.

If you want to experiment and develop the carbon widgetset interface, look at Installing Carbon on OSX.

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-0.9.6-20050225-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 get a Lazarus Snapshot for Windows at: http://www.de.freepascal.org/lazarus/

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:

http://www.de.freepascal.org/lazarus/

Then unzip it to c:\lazarus for example. You have to install at least fpc-2.0.0, but a fpc-2.0.1 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.
