Open Source Desktop Operating Systems 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.

The Lazarus IDE is a stable and feature rich visual programming environment for the FreePascal Compiler. It supports the creation of self-standing graphical and console applications and runs on Linux, FreeBSD, MacOSX and Windows.

A gdb-like debugger for bash

SETEdit is a friendly text editor. It is a text mode application with windows, buttons, mouse support, etc. The main target of the project are programmers so the editor is mainly oriented to programming.

CeGCC is a cross-development environment for creating Windows CE (Pocket PC) applications, from a Linux, Cygwin, or MacOS-X host PC.

DUMA (Detect Unintended Memory Access) is a multi-platform memory debugging library. It can detect memory leaks and buffer overruns (or underruns) in a malloc() / new memory buffer. DUMA is a fork of Bruce Perens' Electric Fence library. sourceforge isn't maintained for many years! suggest you want to look at https://github.com/johnsonjh/duma

NB: Development has been moved to Github: https://github.com/avrdudes/avarice AVaRICE is a program for interfacing the Atmel JTAG ICE to GDB to allow users to debug their embedded AVR target.

Development environment for OS/2 and DOS

After a program has been thrown into the world in binary form, it can boomerang back as source code. The Boomerang reverse engineering framework is the first general native executable decompiler available to the public.

The ECLiPSe Constraint Logic Programming System is designed for solving combinatorial optimization problems, for the development of new constraint solver technology and their hybrids, and for the teaching of modelling, solving and search techniques.

MSPDebug is a free debugger for use with MSP430 MCUs. It supports FET430UIF, eZ430, RF2500 and Olimex MSP-JTAG-TINY programmers. It can be used as a proxy for gdb or as an independent debugger with support for programming, disassembly and reverse eng

RHIDE is an integrated development environment with inetgrated debugger GDB

A retargettable micro-controller and embedded system emulator architecture, providing common supports to emulate various types of micro-processors & devices on an x86 PC. Development of emulation for Arduino and various shields is just about to be launched in 2012.

Camelia is an IDE for OCaml designed with students and new users in mind. It sports syntax highlighting, tool-tip type checking, clickable error explanations, an integrated debugger, and more.

BuGLe combines a graphical OpenGL debugger with a selection of filters on the OpenGL command stream. The debugger allows viewing of state, textures, framebuffers and shaders, while the filters allow for logging, error checking, video capture and more.

Tool for monitoring of OCI client applications [f.e.: TOAD/TOra, or any OCI-based fat client] interaction with Oracle Database. Monitors SQL statements and values passed/fetched between client application and RDBMS. Consists of simple and nice GUI [C#] and events handler [C++] with quite a lot of OCI hacking. Interface between handlers and tool's GUI is through tailing of XML "pipeline" files in $HOME/.ocimonitor directory. Tool is quite similar to Quest SQLMonitor, which is unable to trace values.

ELFIO is a header-only C++ library intended for reading and generating files in the ELF binary format

Warning: Older projects may have to be compiled with -DDEBUG_NEW_CONFIG_HAVE_DEPRECATED Debug_New offers the possibility of debugging memoryleaks, not only (note the "not only"; that's just one of its functions) in a <report-memory-leaks-on-shutdown> kind of way, but implemented using memory-states. - Cross platform + Cross compiler support (only utilizes the preprocessor and template-voodoo-magic for c++) - Supports C and C++ - Supports gcc and g++ - Supports pthread and any posix platform - Multithreading is supported. - Easy to use and install (just include the header and link the source). - Easily debug memory-leaks. - Easily debug dangling pointers. - Easily debug deallocation method correctness. - Easily debug array index errors (when writing past the end). - Easily profile memory usage and track down memory hawks. - Click-And-Goto-Source support for Visual Studio. - Integrated compatibility for new, new[], delete, delete[], malloc, calloc, realloc, free

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

Displaying information about the contents of COFF format files which were built by CCS compiling tools of Texas Instruments; disassembling such COFF files.

Simulator for 486 processor. Can be customized for embedded system emulation.

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

The "JTAG-GDB server" is a program for integrating the ARM-Embedded ICE logic with the GNU-Debugger GDB.

This is a project to develop tools for the MOUSE programming language and to encourage its use as an experimental and teaching language.

Mickey is a hex/ascii file viewer and editor that runs on all major operating systems thanks to FLTK.
