GDB, the GNU debugger, allows you to debug programs written in C, C++, and other languages, by executing them in a controlled fashion, printing their data, etc., on a wide variety of UNIX and non-UNIX systems. hot
cgdb is a curses-based interface to the GNU Debugger (GDB). The goal of cgdb is to be lightweight and responsive; not encumbered with unnecessary features. The interface is designed to deliver the familiar GDB text interface, with a split screen showing the source as it executes. The UI is modeled on the classic Unix text editor, vi. Those familiar with vi should feel right at home using CGDB.
Code Medic provides an elegant graphical interface to gdb's most important features.
GNU DDD is a graphical front-end for command-line debuggers such as GDB, DBX, WDB, Ladebug, JDB, XDB, the Perl debugger, the bash debugger, or the Python debugger. Besides 'usual' front-end features such as viewing source texts, DDD has become famous through its interactive graphical data display, where data structures are displayed as graphs.
Insight is a graphical user interface to GDB, the GNU Debugger written in Tcl/Tk.
KDbg is a graphical user interface to gdb, the GNU debugger. It provides an intuitive interface for setting breakpoints, inspecting variables, and stepping through code. KDbg requires KDE, the K Desktop Environment, but you can of course debug any program.
RTL-check is a framework for static analysis of programs from a safety and security perspective. It performs analysis on RTL, which is the low-level intermediate representation generated by GCC.
vidbg is a full screen, text mode wrapper around gdb. It is intended to be a very lightweight source level debugger. All interaction with gdb is through vi-like keystrokes.
