Compiling Event Generator Software

Introductory Topics

The code was developed using the latest cygwin installation on Windows NT, then tested on Windows 2000 and the SLAC Redhat Linux cluster. The procedures are listed here as reference for individuals attempting to compile their own, customized installation. If you're reading this page you've either encountered problems installing the existing libraries, or you are interested in making changes of your own to the provided software, or you're porting the code to another platform. 

Linux

• First, ensure that you are running Java 2.

  > java -version  

  should give something like "Java(TM) 2 Runtime Environment"

   

• Make sure you are running at least version 2.95 of the Gnu Compiler Collection.

  >gcc -v

  should give something like "gcc version 2.95.2 19991024 (release)"

• Set your shell, e.g.

  >tcsh

   

• Locate your Java installation, e.g.

  >setenv JDK_ROOT myinstalldir/jdk1.3.1

   

• Navigate to the generator XX source directory in your working area (under Software/EvtGen).

  >cd XX

   

• Compile and build the shared object library for generator XX

  >gcc-2.95 -shared -I$JDK_ROOT/include -I$JDK_ROOT/include/linux *.cpp *.f -lg2c -o libXXevtgen.so

   

• Copy this to your working area 

  >mv libXXevtgen.so ../.

   

• Go to your working area and generate events!

  >cd ..

  >java EvtGen 1 XX

Windows

• Ensure you have the latest version of cygwin.
• Start cygwin by clicking on the desktop icon.
• Ensure that you are running Java 2 

  >java -version  

  should give something like "Java(TM) 2 Runtime Environment".

   

• Navigate into the generator XX source directory in your working area (under Software/EvtGen).

  >cd XX

   

• Makefiles "MakeEvtGen" are provided which you will have to customize to your individual environments.

  The only thing you should have to change is the location of JDK_ROOT!

   

• Compile the code and build the necessary dynamic link library.

  >make -f MakeEvtGen

   

• Copy  XXevtgen.dll up to your working area.

  >mv XXevtgen.dll ../.

   

• Go to your working area and generate events!

  >cd ..

  >java EvtGen 1 XX
