1. If you're using Windows, please download cygwin from
     http://www.cygwin.com/. This is not required for Linux.

  2. JDK 1.4 (or above) from http://java.sun.org/ (For development
     with SVMDCP, JDK 1.4 or higher is required; for execution of
     binary release, JRE 1.3 is enough, provided that "-target 1.3"
     flag is specified while compiling.)

  3. AspectJ 1.1 (or above) from http://aspectj.org/.

  4. JavaCC 3.2 (or above) from https://javacc.dev.java.net/.

  5. Make sure the following programs are in your PATH:
       java and javac (Java tools)
       ajc (AspectJ compiler)
       javacc (JavaCC compiler)

INSTRUCTIONS:

  1. Obtain SVMDCP from CVS:
     $ export CVS_RSH="ssh"
     $ cvs -z3 -d:ext:anoncvs@savannah.nongnu.org:/cvsroot/svm co svmdcp

  2. Build SVMDCP from source:
     $ export CLASSPATH=`pwd`:$CLASSPATH
       (add the parent directory of svmdcp to CLASSPATH)
     $ export ASPECTJ_HOME=$HOME/aspectj1.1 && export CLASSPATH=$ASPECTJ_HOME/lib/aspectjrt.jar:$CLASSPATH
       (add the AdpectJ runtime package to CLASSPATH, ASPECTJ_HOME might be different for your case)
     $ cd svmdcp
     $ LANG=C make
       (make SVMDCP, set LANG=C because JavaCC has a bug for non-European systems)

  3. Build Ptolemy II:
     $ cd ..
     get Ptolemy source from http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII3.0/ptII3.0.2.src.tar.gz
     $ tar -zxvf ptII3.0.2.src.tar.gz
     $ cd ptII3.0.2
     $ export PTII=`pwd`
       (set PTII to the current path)
     $ ./configure && make
     go to have a cup of coffee or two; when back,
     $ bin/vergil
       (try to see if Ptolemy works, especially, if its Expression demo works)

  4. Add rollback support to Ptolemy Expression model:
     get the dependency list from http://msdl.cs.mcgill.ca/people/tfeng/uml/svmdcp/aspects.new.lst
     $ java svmdcp.DCPGenerator.DCPGenerator `cat aspects.new.lst`
       (generate aspects for every file listed in aspects.new.lst)
     get http://msdl.cs.mcgill.ca/people/tfeng/uml/svmdcp/VergilApplication.java and save it to ptolemy/vergil/
       (overwrite the old one)
     $ rm -f ptolemy/vergil/VergilApplication*.class
       (remove the old class file, otherwise vergil might not be correctly re-built)
     $ JAVAC_FILE=`which javac`
     $ mv $JAVAC_FILE `dirname $JAVAC_FILE`/javac.bak
     $ pico $JAVAC_FILE
     input the following to the file and save it (modify SVMDCP_PATH and ASPECTJ_PATH):

       #!/bin/bash
       # -- change these variables according to your system
       SVMDCP_PATH=$HOME/projects/svmdcp
       ASPECTJ_PATH=$HOME/aspectj1.1
       # --
       osys=`uname -s`
       nsys=${osys/CYGWIN/}
       if [[ $osys != $nsys ]]; then
         PATHSEP=";"
       else
         PATHSEP=":"
       fi
       CLASSPATH="${SVMDCP_PATH}/..${PATHSEP}${ASPECTJ_PATH}/lib/aspectjrt.jar${PATHSEP}$CLASSPATH"
       param=${@/-O/}
       ajc -classpath $CLASSPATH $param

     $ chmod +x $JAVAC_FILE
     $ make -C ptolemy
       (re-build Ptolemy, Good Luck!)
     $ mv `dirname $JAVAC_FILE`/javac.bak $JAVAC_FILE
     $ bin/vergil
       (re-start vergil, and test the new Expression demo)

  Up to this point, the building is finished, for more information on
  the SVMDCP project, please go to its homepage
  (http://msdl.cs.mcgill.ca/people/tfeng/?research=svmdcp).

  Enjoy! -- Thomas Feng
