Open Source MinGW/MSYS2 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.

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

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

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.

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

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.

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.

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.

Free MSP430 Debugger is developed in two steps : a library to provide access to the debugger hardware, and a "gdbproxy" to allow users to debug their software. This project is currently working with OLIMEX MSP430 JTAG ISO & msp430-gdbproxy.

Allows GCC/MinGW to use Wine's stacktrace library dbghelp.dll ( since Wine's dbghelp can read GCC's dwarf2 debug info ).

GDBShell is FREE simplest graphical frontend for GDB (Gnu DeBugger), working under Win32. This tool is very light weight, but made GDB more usable for you.

The NT POSIX C Runtime Library is an IEEE standard runtime library for the NT POSIX subsystem. It can be used as a complete replacement or a side by side alternative for what is shipped with the Interix SDK.

A microkernel operating system distribution offering (among other things) very low hardware requirements, full and easy portability and easy-readable source code.

Pluk is a programming language. Something i am building because i want a compiled java/c# variant.

This project is for homebrew console development tools based on the gnu compiler collection with additional tools and libraries to aid programming each supported console. The windows variants are built with MinGW.

A tiny and easy to use log library for C/C++. Written in C. Customizable log message format for global and specified output target Cross platform support. Tested: linux, win32, wince, mac

Libinstrument is a complete and easy way to do custom function instrumentation for C/C++. The project comes ready with classic applications of instrumentation, such as AOP (Aspect Oriented Programming), Concern and Side Effect injection, stack tracing, exception tracing, basic time profiling, callgraph profiling and other. A GC (Garbage Collector) module is also under development. Libinstrument is highly portable and decoupled. The project comes with a CMake build system, integration with IDEs (CLion, Eclipse e.t.c) is straightforward. Using lazy algorithms there is virtually zero overhead in benchmarks and minimum overhead in execution time. Libinstrument tries to be as non-intrusive as possible, while trying to help the developer offering basic reflection. There are Unit Tests for each class and method, testing is driven with CTest.

Tool to convert stabs debugging symbols into Codeview symbols within Windows 32 bit executables. This tool allows one to use Windows debugger tools on applications built with GCC.
