Installation hints for lazarus ============================== Lazarus provides two main parts: - LCL - the Lazarus Component Library - IDE - the RAD tool (editor, form designer, GUI for debugger and compiler, ...) What is required for Lazarus: - FreePascal - the FreePascal Compiler plus packages plus FPC sources. IMPORTANT: try to get the same version of the compiler sources as the installed compiler. - Under Linux/xxxBSD: gtk2 libaries - Most distributions already install them. See www.gtk.org. The FAQ - Frequently Asked Question is available at www.lazarus.freepascal.org and some can be found in the file 'FAQ'. The following will describe how to get FreePascal and how to install Lazarus properly: ================================================================================ 1. Quick installation guide -------------------------------------------------------------------------------- 1.1 This is the short version. For more details, see the following sections. Lazarus is intended to be a development tool. Therefore it is designed, that any normal user can easily install his local copy. This means Lazarus does not need to be installed as root and it does not create any symlinks or configuration entries. You can literally just unpack it into a directory of your choice and compile it. 1.2 Under Linux/BSD: Make sure that you have installed X, gtk2 and gtk2-devel. Fedora: yum install gtk2 gtk2-devel Debian/Ubuntu: apt-get install lazarus #will pull in required gtk dependencies Download and install FreePascal. Either the rpm, tgz or the daily snapshot. You need at least FPC 3.2.0 (3.2.2 is the stable version of FPC; uneven versions like 3.3.1 are development versions). To compile Lazarus (LCL + IDE) go to your unpacked Lazarus source and do: []$ make clean all You don't need "./configure" and you don't need "make install". You now already have a complete Lazarus. You can start the IDE with "./lazarus". The "make install" as root will just copy the files and set some nice symlinks and desktop entries. 1.3 Under Mac OS X: What you need: Apple Developer tools The Developer tools are included on the original OSX installation CDs, or can be downloaded at ADC (free registration required) http://developer.apple.com/. Download and install FreePascal. Either the dmg or the daily snapshot. You need at least FPC 3.2.0 (3.2.2 is the stable version of FPC; uneven versions like 3.3.1 are development versions). To compile Lazarus (LCL + IDE) go to your unpacked Lazarus source and do: []$ make clean all You don't need "./configure" and you don't need "make install". You now have already a complete lazarus. You can start the IDE with "./lazarus". The "make install" as root will just copy the files and set some nice symlinks and desktop entries. ================================================================================ 2. Installing FreePascal -------------------------------------------------------------------------------- 2.1 Installing FreePascal under Linux: Lazarus requires FPC (Free Pascal) version 3.2.0 (or newer) and it requires both the compiled FPC libs (binaries) and the FPC sources. Most of the Linux distributions contain packages for FreePascal (look for FPC). Use your package manager to install them. The FPC binaries: At the Lazarus downloads section (www.lazarus.freepascal.org or http://sourceforge.net/project/showfiles.php?group_id=89339) you can get the rpm/deb of the Free Pascal compiler(compiler / linux) and its packages. Alternatively, if you don't have a rpm system, you can download and install the tars from www.freepascal.org. If you want to compile the binaries for yourself see the BSD section. The FPC sources: The easiest way to get the Free Pascal sources is via git. Of course you can also download it as whole, see http://www.freepascal.org/develop.html for the daily snapshot of the release tree (3.3.x). The FPC sources via git: Create a directory where you would like to put the sources. You don't need to be root to do this. First create a directory for fpc (e.g. /home/username/freepascal) then do the following: []$ bash []$ git clone https://gitlab.com/freepascal.org/fpc/source.git []$ git switch main This will create a directory fpc, which can later be used in the IDE. Hint: To download/update the latest changes you can simply do []$ cd /home/username/freepascal/fpc []$ git pull -------------------------------------------------------------------------------- 2.2 Installing FreePascal under Windows: If you use the Windows installer for lazarus, then you don't need to install Free Pascal separately, because the installer already contains the necessary files. See http://www.freepascal.org/down-win32.html. You can find a list of mirrors at http://www.freepascal.org/sdown.html. Download for example FPC as one big file, unzip it and run install.exe. Then extend your PATH variable to the FPC directory. For example under Windows 98: Edit autoexec.bat and add the line PATH=%PATH%;C:\pp\bin\bin\win32 Then restart Windows. ToDo: explain how to download fpc sources and build the compiler -------------------------------------------------------------------------------- 2.3 Installing FreePascal under BSD/manually: Read 1.2 first. 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 .git/ dirs). The above file misses this (2) Lazarus source snapshot. - _any_ starting compiler from the 3.2.2 branch) You can do a check by parsing the output of 'fpc -v' if it is 3.2.2, it is ok. - dependant packages. (for FreeBSD that is gtk2, 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/3.2.2/ppc386 $THEPREFIX/bin/ppc386 install sourceinstall PREFIX=$THEPREFIX (5) (configure) run compiler/utils/samplecfg $THEPREFIX/lib/fpc/3.2.2 $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 $ETCDIR should be user configurable. Otherwise local installs aren't possible. - BSDHIER=1 on all make commands forces BSD hierarchy conventions. -------------------------------------------------------------------------------- 2.4 Installing FPC on Mac OSX Read 1.3 first. Information: http://www.freepascal.org/fpcmac.html#TargetDarwin Download the latest Mac OSX dmg package. Since FPC for Mac OSX is under heavy development, it s recommended to use the latest FPC from git. Open a terminal and type (without the []$) []$ git clone https://gitlab.com/freepascal.org/fpc/source.git []$ git switch main This will create a directory fpc, which can also be later used by the IDE. Compile fpc: []$ make clean all Install fpc []$ sudo make install This will install fpc in /usr/local/bin. The compiler is for example /usr/local/bin/fpc. You can add the path to your /Users/username/.profile. Hint: To download/update the latest changes you can simply do []$ cd /Users/username/fpc []$ git pull ================================================================================ 3. Installing Lazarus -------------------------------------------------------------------------------- 3.1 Installing Lazarus under Linux/BSD/Mac OSX: 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/zip files from the downloads section or you can download it directly via git. Hint: Most Linux distributions contain a Lazarus package. Go to your package manager and install it. Downloading Lazarus git: git 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 to be root. Lazarus does not need any special permissions, neither during installation nor at runtime. First create a directory for Lazarus (e.g. /home/username/freepascal) then do the following: connect to the git server (note: Lazarus and Free Pascal use the same server) []$ git clone https://gitlab.com/freepascal.org/lazarus/lazarus.git []$ git switch main compile Lazarus: []$ cd lazarus []$ make (gmake on BSD) If FPC is installed correctly, the compilation should work without problems. If not, see the 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 Free Pascal 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/share/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 []$ cd /home/username/freepascal/lazarus []$ git pull []$ make clean all (gmake on BSD) This will rebuild Lazarus and create a minimal IDE with only the basic packages. []$ make idepkg -------------------------------------------------------------------------------- 3.1 Installing Lazarus under Windows: Just download and install the .exe file. You can get the files from: http://sourceforge.net/project/showfiles.php?group_id=89339 (stable release) Thanks to Joe for this Step-by-step description: You have to download the Lazarus source: ftp://ftp.freepascal.org/pub/fpc/source/lazarus.zip Then unzip it to c:\lazarus for example. You have to install at least FPC 3.2.0, e.g. in c:\pp\bin\win32. In this directory you can find a lot of exes (make, grep, ppc386, and so on). Open a command line. Start->Run...>command or choose MS-DOS icon. Type: cd c:\lazarus rem of course adjust to your path: set path=c:\pp\bin\win32;c:\lazarus make If you are lucky then you can type: lazarus.exe
