How to use valgrind

1. Check you run in debug mode
   % echo $NODEBUG
   should give:
   NODEBUG: Undefined variable.
   If not do
   % unsetenv NODEBUG
   % stardev

    

2. Compile your code using cons
   ex: % cons +Hbt

    

3. Run valgrind by default. There are 2 cases
   
   1. Version valgrind-20030725 on RedHat 7.2
      % valgrind `which root4star` -b -q 'macros.C()'
   2. Version valgrind-2.1.1 on RedHat 8.0 greater
      % valgrind --tool=memcheck `which root4star` -b -q 'macros.C()'
   We do not intend to upgrade the infrastructure on Redhat 7.2.
4. You can add some options, for example
   • To redirect outputs in a file:  --log-file=Valgrind.log
   • To check memory leaks   :  --leak-check=yes
