  • Installation Instructions for for CbmRoot

    1. Dependencies

    1.1 Compiler

    To be able to compile CbmRoot a compiler with full C++11 support is needed. GCC since version 4.8 and clang since version 3.4 are known to work without problems.

    1.2 FairSoft

    To install, compile, and run CbmRoot several external programs are required. This are for example Root, Geant3 or Geant4. The complete list can be found on the FairRoot webpage (fairroot.gsi.de). Since most of these programs can't be installed using the package manager of the used Linux distribution, or at least can't be installed in the required version, the FairRoot team provides a GIT repository with all needed packages and some scripts to automatically build and install these so called external packages.

    Detailed instructions how to get and compile FairSoft (aka external packages) can be found at the following webpage

    https://redmine.cbm.gsi.de/projects/cbmroot/wiki/Install_External_Packages

    Please make sure SQLite is installed on your system before compiling FairSoft, as this is required by CbmRoot. Failing compile FairSoft with SQLite support will lead to a crash during the CbmRoot compilation. To install SQLite on Debian/Ubuntu and OpenSuse use

    Debian/Ubuntu:

    sudo apt install sqlite3 libsqlite3-dev

    OpenSuse:

    sudo zypper install sqlite3 sqlite3-devel

    It is currently not recommended to install FairSoft (and likewise FairRoot and CbmRoot) with administrator privileges, as this may create conflicts with existing software. For an installation which is to be shared between users on a MacOS or linux system it is recommended to use the opt/ folder. Consider also using the auto installer (see section 3).

    If you are working at GSI there are always ready-to-use versions of FairSoft available. For detailed information please check the following wiki page

    https://redmine.cbm.gsi.de/projects/cbmroot/wiki/RunCbmGSI

    1.3 FairRoot

    CbmRoot is based on FairRoot, a package which meanwhile serves several experiments as base for their developments. Beside FairSoft you need also to install FairRoot to be able to compile CbmRoot

    Detailed instructions how to get and compile FairRoot can be found at the following webpage

    https://redmine.cbm.gsi.de/projects/cbmroot/wiki/InstallFairRoot

    2. Recommended versions

    GCC : >= 4.8 or Clang: >= 3.4

    FairSoft: jun19p2

    FairRoot: v18.2.1

    3. Automatic installation

    To make the installation more easy we provide a script which automatically gets and installs FairSoft, FairRoot, and CbmRoot in one go. The script always take the correct FairSoft and FairRoot versions. The full description of this process is at

    https://redmine.cbm.gsi.de/projects/cbmroot/wiki/InstallCbmRootAuto

    The one line command which has to be executed inside the CbmRoot source directory is

    ./autoinstall_framework.sh 1 1 1

    4. Further remarks

    Compiling CbmRoot with multicore support using "make -j", without specifying the number of threads is known to cause MacOS and Ubuntu 20.04 LTS systems to freeze. Please explicitly choose a number of cores which is suitable for your system.
