Installing and Testing MarlinReco on Linux

Overview

The MarlinReco package provides a suite of reconstruction software including an event processor and event display.

These are step-by-step instructions for installing on Linux.

Procedure

1. Create a working directory

   mkdir MarlinReco
   cd MarlinReco
   

2. Obtain and unpack the installation files

   wget http://www-flc.desy.de/software/MarlinReco/MarlinReco_Linux_install.tar.gz
   tar -zxvf MarlinReco_Linux_install.tar.gz
   cd linux
   tar -zxvf ilcsoft.tar.gz
   

3. Update the hardcoded /opt/products path for your installation

   chmod 755 update_path.sh
   . update_path.sh marlin/0.9.1/env.sh
   . update_path.sh marlin/0.9.1/userlib.gmk
   

4. Setup ROOT (OPTIONAL)

   source setup-root.sh # specific to my environment
   

5. Set the Marlin environment

   cd marlin/0.9.1
   source env.sh_ORG
   

6. Rebuild Marlin and the MarlinReco packages (OPTIONAL)

   gmake clean
   gmake
   

7. Reconfigure CED event display (if necessary)

   cd ../..
   cd CED
   

   At my Linux site, libglut.so.3 was not in the standard location, so I moved it to the CED area for convenience. Skip this step if you have the Mesa GLUT library properly installed.

   cp /path/to/libglut.so.3 . # only if not in standard location
   export LD_LIBRARY_PATH=$(pwd)
   

8. Start the event display

   glced &
   

   No you should see glced in the process list.

   [1206 $] ps
     PID TTY          TIME CMD
    4853 pts/9    00:00:00 glced
   

9. Run an example

   cd $MARLIN/packages/MarlinReco/examples/LDC
   $MARLIN/bin/Marlin steer_ldc.xml
   

Now, you should have MarlinReco running with CED displaying events.

Enjoy.
