Debuggers

• GNU/Linux debugger: gdb
• Graphical front-end: ddd
• Designed for Fortran/C, not C++
• Can debug C++ programs but has troubles on complex objects (use the ``insert a print statement'' technique when gdb fails)
• Memory debugger: valgrind (to track pointer bugs)
• In order to debug, compile with -g flag: c++ -g -o helloworld helloworld.cxx
