Subject:  Howto use valgrind on full screen kiosk app.



I had to test a full screen application with valgrind.

#----------------------------------------
SSH into remote host as regular user.

#----------------------------------------
Since we don't start fluxbox with the command startfluxbox,
we can't start the app with a line in ~/.fluxbox/startup:
  ~/.fluxbox/autostart.sh &

#----------------------------------------
Insted add the following line to ~/.fluxbox/init:
  
  session.screen0.rootCommand:             ~/.fluxbox/autostart.sh

#----------------------------------------
Add the follwing to  ~/.fluxbox/autostart.sh:

  #!/bin/bash
  cd /sim3/;
  ~/bin/my_app.sh &

#----------------------------------------
My ~/bin/my_app.sh file looks liek this:

  #!/bin/bash
  cd /app_directory/

  export LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH
  export PATH=./$PATH:/usr/sbin:/sbin

  Debug="1"
  if [ $Debug == "1" ]; then
    # Debug with Valgrind
    valgrind -v --tool=memcheck --leak-check=yes  --num-callers=10  --gen-suppressions=yes --suppressions=/sim3_valgrind_suppression.supp  --db-attach=yes ./my_app
  elif [ $Debug == "2" ]; then
    # Debug with strace
    /usr/bin/strace -f -s100 -q -o /tmp/strace.txt ./my_app
  else
    # No Debug
    ./my_app
  fi

#----------------------------------------
SSH to the remote host, and type:
  xinit /usr/bin/fluxbox
