Installation

The T49DST and T49ANA libraries are part of the local-branch of the NA49-library and can be used on the NA49-Linux-PCs (na49i01-10).

To do so, you should add the following to your .rootrc:

       # Path used by dynamic loader to find shared libraries
       *.Root.DynamicPath:    .:$ROOTSYS/lib:$NA49/local/lib

Make sure the that the NA49-environmentals are all set:

       setenv NA49_LEVEL new
       source $NA49/etc/na49_env.csh

And define the T49-environment:

       source $NA49/local/T49/macro/T49_env.csh

If you want to install the libraries on your own machines away from CERN, please follow this procedure:

Make sure that ROOT is installed properly on your machine

Create a top-directory (e.g. T49) on your machine

Add the following lines to your .(t)cshrc:

       setenv NA49_ARCH   Linux
       setenv T49DST     <your topdirectory>/T49DST
       setenv T49DST_LIB "$T49DST/lib"
       setenv T49ANA     <your topdirectory>/T49ANA
       setenv T49ANA_LIB "$T49ANA/lib"
       setenv NEW_PATH        "$T49DST_LIB":"$T49ANA_LIB"
       setenv LD_LIBRARY_PATH "$NEW_PATH":"$LD_LIBRARY_PATH"

In the T49/dist-directory of the NA49-library (local-branch) you can find the file T49.tar.gz. (Or simply download it here.)
Copy this file to your top-directory and unpack it with the command

       tar -xvzf T49.tar.gz

This will create the directory tree and write out the source- and header-files.

Create the following underdirectories:

       <your topdirectory>/bin

and

       <your topdirectory>/T49DST/lib
       <your topdirectory>/T49ANA/lib

Create the libraries by executing

       make nods <your topdirectory>/bin
       make nods <your topdirectory>/T49DST/lib                 
       make nods <your topdirectory>/T49ANA/lib

If everything went fine, you should find libT49DST.so in T49DST/lib and libT49ANA.so in T49ANA/lib as well as root49 (without TRootDS).
Note, that creating the root49-executable is only possible when you have installed DSPACK properly on your machine.

Add the following to your .rootrc:

       # Path used by dynamic loader to find shared libraries
       *.Root.DynamicPath:    .:$ROOTSYS/lib:$T49DST_LIB:$T49ANA_LIB

If you are using mini-DST copies somewhere else than at CERN, you have to define ROOT49 accordingly:

       setenv ROOT49     <your directory containing .root49dsts>
