Before installing FairRoot many other packages are necessary. Some of them can be installed using the package manager of the used Linux distribution, but many others have to be installed from sources. This is necessary because many of these programs can't be installed using the package manager or FairSoft need the programs compiled with special settings.

To make the installation procedure as easy as possible we provide an additional package called FairSoft (sometimes also called "external packages") which takes care of the installation of all needed programs in the right order and with the right compilation flags. In the end all additional software is installed in one directory.

The FairSoft package contains a configuration scripts which checks if all the needed system packages are installed. If some of the system packages are missing the configuration script will stop with a detailed error message. The complete list of needed system packages can be found in the DEPENDENCIES file. This file contain also complete command lines to install the needed packages on the most common Linux systems.

The main prerequisite for the FairSoft installation on Linux or Mac OSX systems is CMake which has either to be installed using the package manager or from the sources which can be downloaded from here.

The instructions how to install FairSoft can be found here.

To install FairSoft on your computer make sure that the following prerequisites are fulfilled on your system. It is no problem if you miss some package since the installation script will check for the existence of the needed packages and prints an error message if not all packages are detected. If you are unsure about the package names on your Linux system check the DEPENDENCIES file. There you will find a list of the dependencies which are needed to be able to compile FairSoft. In this file you can also find complete comand lines for different Linux distributions which will instruct the package manager to install all needed software packages.

After downloading FairSoft from our github repository (see bellow) call the "./configure.sh" script in the downloaded directory and folow the instructions on the screen. A detailed description and a complete list of contained software packages can be found in the file README.md (either in the source directory or here)
The new version of the configure script needs CMake as prerequisite. This package should be installed using the package manager of the used Linux distribution. If this is not possible the source code can be downloaded from here and installed using the instructions given on the web page. The configure script will then check if all other prerequisites are installed on the system.

• The external packages are moved to GitHub. New releases are available from:
  https://github.com/FairRootGroup/FairSoft

• A complete list of releases are available from:
  https://github.com/FairRootGroup/FairSoft/releases

• Install the external packages in a directory of your choice
• set the variable SIMPATH to your external packages directory
• Get FairRoot source code from GitHub
  > git clone https://github.com/FairRootGroup/FairRoot.git
• Create a build directory (build in source is not allowd)
  > mkdir build
  > cd build
• Call cmake to create your make files or project files for Xcode. Eclipse, KDeveloper, etc.
  >cmake -DCMAKE_INSTALL_PREFIX="Specify an installation directory" "Path to FairRoot source"
• In case of creating standard makefiles, call make
  > make (make install)
• FairRoot is now compiled and installed you can go to the example directory and run the tutorials
