Open Source Debuggers

MinGW: A native Windows port of the GNU Compiler Collection (GCC), with freely distributable import libraries and header files for building native Windows applications; includes extensions to the MSVC runtime to support C99 functionality. All of MinGW's software will execute on the 64bit Windows platforms.

Code::Blocks is a free, open-source, cross-platform C, C++ and Fortran IDE built to meet the most demanding needs of its users. It is designed to be very extensible and fully configurable. Finally, an IDE with all the features you need, having a consistent look, feel and operation across platforms. Built around a plugin framework, Code::Blocks can be extended with plugins. Any kind of functionality can be added by installing/coding a plugin. For instance, compiling and debugging functionality is already provided by plugins! We hope you enjoy using Code::Blocks! The Code::Blocks Team

WinAVR (tm) is a suite of executable, open source software development tools for the Atmel AVR series of RISC microprocessors hosted on the Windows platform. Includes the GNU GCC compiler for C and C++.

The strace project has been moved to https://strace.io. strace is a diagnostic, debugging and instructional userspace tracer for Linux. It is used to monitor and tamper with interactions between userspace processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state. The operation of strace is made possible by the kernel feature known as ptrace.

HT is a file editor/viewer/analyzer for executables. The goal is to combine the low-level functionality of a debugger and the usability of IDEs. We plan to implement all (hex-)editing features and support of the most important file formats.

Serial line sniffer (slsnif). slsnif is a serial port logging utility. It listens to the specified serial port and logs all data going through this port in both directions.

Daphne is a system tray application for process killing, controlling and debugging. It's development started back in 2005. It was first thought to kill a set of windows process at once. With the time it became a GPL task manager replacement for Windows. You can kill a process by dragging the mouse over the windows, by right-clicking the process in the main process list, or by typing its name with the "Kill all by name" command. You can set a any window to be always on top, to be transparent, to be enable, et cetera. Although Daphne was born just to kill windows process. You can think of Daphne as a task manager replacement. The main window displays a list of currently running process with detailed information about: CPU usage, Process ID, Process name, Full path (and arguments), Priority, Class (Process / Service), Current memory usage, Peek memory usage, Current swap usage, Peek swap usage and Number of threads.

Cinemagoer is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. Platform-independent, it can retrieve data from both the IMDb's web server and a local copy of the whole db.

ptkdb is a debugger for perl using a Perl Tk GUI as its interface.

Tool for iOS crash logs (crash report) symbolicating ( for OS Windows )

The Pajé visualization tool provides interactive and scalable behavioral visualizations of the dynamics of the executions of parallel and distributed applications.

mpatrol is a link library that attempts to diagnose run-time errors that are caused by the wrong use of dynamically allocated memory, including writing to free memory and memory leaks.

logview4net is a log viewer/log monitor for data created by various sources. It can listen to UDP, tail a file, tail a SQL table, monitor the eventlog and watch RSS and Atom feeds. It requires the Microsoft .NET Framework 2.0

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. DDD displays data structures as graphs and plots.

Avrora is a suite of tools for analyzing and debugging programs for AVR microcontrollers. It has support for a sensor platforms such as Mica2 and MicaZ, allowing wireless network simulation and allows dynamic instrumentation and static analysis.

The debug memory or "dmalloc" library has been designed as a drop in replacement for the system's malloc, realloc, calloc, free and other memory management routines while providing powerful debugging facilities configurable at runtime.

SPE is a python IDE with auto indentation&completion,call tips,syntax coloring&highlighting,uml viewer,class explorer,source index,todo list,pycrust shell,file browsers,drag&drop,Blender support.Spe ships with wxGlade,PyChecker and Kiki.

An advanced portable C++ library of over 80 boolean-like macros that hold an analysis if the condition fails, to help debugging, so a developer knows exactly what goes wrong. Allows reuse in adapted assertion macros, as in ModAssert (also on sourceforge) and UquoniTest (a unit test library for C++). Needs STL or wxWidgets.

AProf is a profiler for the Amiga computer. It can be used with all Amiga development languages that support the standard AmigaDOS symbol hunk format. The application offers execution time measurements in several different ways, allows filtering/sorting

Adebug/Assemble is a pair of Debugger/Assembler for the MC68Xxx family running on Atari and Amiga computers. Years ago commercial product, now GPL.

AlphaBase is a very powerful Bash which may help you to debug your PSP and provides you useful instruments like: Macro System, Commands Creator, LUA Parser with some advantages on complex math calculator. It has all the functionalities of a normal shell, but it was especially coded for anyone who wants to write a PSP LUA Program so could be named apparently as another LUA IDE even if it isn't really. By its being multi-environment and multi-user, it privileges security: there is a very complex Login System with hierarchy levels that could be set by an Admin. The Admin could also perform bans or suspensions on every non-admin user that executes unappropriate code for the AlphaBase Environment. AB provides also a multi-medial set of commands that allows you to, for example, print a text using a font file previously loaded, to draw a rectangle, a line, to blit images, to associate some screen ares to a certain commands set that could be clicked by a cursor etc...

A front end of any dump analyzer ,its purpose to assist developers to analyze dumps generated by processors and find the reason of crash.

The Developer Resources Sega Genesis and Super Nintendo development tools and libraries In 1992 I (Kevin Seghetti) and some friends had a company (Developer Resources) which provided development tools for the Sega Genesis and the Super Nintendo console

Excellent macro based library to see program flow, variables, timings, errors, warnings. "Must have" for C/C++ programmers.

The Heap Checker is a library for debugging and developing robust and efficient dynamic memory management and string manipulation in C programs.
