Here's how I set-up an analyzer on my Debian 'Lenny' distribution
I use bash and vim like all right-minded people :-p The Transversity wiki also has lots of good info: Off Line Analysis for transversity
- Install ROOT (if you haven't already)
% apt-get install root-system
- Download and build the analyzer and the d2n replay code
% mkdir d2n_analysis % cd d2n_analysis % wget -nd http://www.jlab.org/~brads/hacks/pull_cvs % chmod a+x pull_cvs
- This script sets the appropriate CVS variables and pulls the d2n/ and analyzer/ branches
% ./pull_cvs
- You should now have two new directories
% ls -F analyzer/ d2n/ pull_cvs*
- Copy and edit the root-setup.sh file. You should update the 'd2n' path at least. 'd2n' needs to point to the directory that you called ./pull_cvs from (ie. which contains the 'analyzer/' and 'd2n/' directories.
% cp d2n/root-setup.sh . % vim setup.sh
- Source the file to set the environment variables
% source root-setup.sh
- Build the base analyzer
% (cd analyzer && make)
- Build the BigBite and replay code
% (cd d2n && ./makeall)
- Now move into the default replay directory
% cd d2n/replay/
- Set up symlinks
The following directories should all be replaced with symlinks summaryfiles/ ScratchROOTfiles/ ROOTfiles/ that all point to an appropriate work disk that is NOT in your $HOME directory. (Your sys-admin and backup software will thank you for it.)
- Now you should be able to run the analyzer as you normally would
NOTE: The environment variables in 'root-setup.sh' need to be
set properly or the analyzer will not work. I put the
script in $HOME/bin and then source it in my .bashrc.
Some Miscellaneous config instructions
- Configure env variables to point to ROOT, etc
If you're not on a JLab CUE system, you may need to edit and source the the 'root-setup.sh' file. The settings in the file work for my debian 'lenny' distribution. YMMV.
- Problem building the BigBite specific libraries in the transversity/ branch
If you see a 'atoi' undefined error when compiling bigbitelib then add the following line to the include list in 'BBDecData.cxx' and recompile. #include <stdlib.h> This fix is in the 'd2n' CVS branch. (22 June 2009, BDS)
