Debuggers on Research Computing's Linux systems

Details

In general, you should use either the debugger that is supplied with each type of compiler or a general purpose debugger like TotalView. The table below provides the compilers and their associated debuggers for the compilers installed on Research Computing Linux computers.

Notes on Debuggers

  • All of the compilers can be used in three different modes: To interactively run and debug a program, to debug a core file that was created by a program, or to connect to a running process. The documentation for each debugger provides information about how to run them.
  • gdb is the debugger used for code compiled with the GNU compilers gcc and g++. It can be run from the command line, from emacs, or xemacs, from ddd or from eclipse.
  • pgdb is the debugger for the Portland Group compilers. If you are running X windows, pgdb has a graphical user interface; otherwise, it has a command-based interface.
  • idb is the debugger for the intel compilers. It can be configured to run using the gdb or dbx commands. It can be run with a command-based interface, from emacs, xemacs, or ddd.
  • jdb is the command line debugger for java.
  • TotalView is a powerful GUI-based debugger that works with several compilers, including GNU, Portland Group and Intel compilers. It can debug MPI, openMP, and other threaded C/C++ or Fortran programs.
