EcoLab is a C++ based Agent Based Modelling system, with emphasis on high performance computing for scaling to large simulations.

Key Objects Library and Mirror Classes Kit (KOL&MCK) and attendant components for Delphi from Delphi2 to DelphiXE is an alternative to VCL to create small applications for Windows platform, freeware with sources. Project was started in 2000, dozens of programmers have created a lot components, helped in fixing a lot of bugs, write pieces of code in the KOL itself.

ACDK - Artefaktur Component Development Kit - is a platform independent C++-framework similar to Java or C#/.NET for generating distributed and scriptable components and applications.

Agar provides a base GUI framework and a standard set of widgets from which graphical applications can be built which run natively under X11, Windows, MacOS, SDL and others. It takes advantage of texture and GPU acceleration wherever available. Agar can also attach to an existing framebuffer, SDL or OpenGL context and operate as a self-contained window-manager. It includes a standard library of general-purpose widgets, and is also designed to be extended externally. New widgets can be implemented as part of an application or library. Complex user interface elements can be realized often in few lines of code. Agar is also extensible at the low-level. The low-level API is documented such that modular drivers can be written which enable Agar applications to work seamlessly under many platforms graphics systems without any change at the application level.

The Windows Extension (WE) is an encapsulation of Windows API. The distinct features of WE are: 1. C++ interface; 2. simple interface for common usage, but advanced usage; 3. low coupling degree; 4. no framework, no pattern.

Caudium WebServer is a single process multi-threaded webserver. It has a built-in pre-processing language and includes an easy to use web-based configuration interface.

Threading Building Blocks offers a rich and complete approach to expressing parallelism in a C++ program. It is a library that helps you leverage multi-core processors for performance and scalability without having to be a threading expert.

AALib/PyAALib - Asynchronous Action Library Project - The project is a Framework based on Pure Object Oriented Concepts to develop asynchronous communication between threads (thread safety) and external process. Platforms: Windows, MacOSX, Linux,Sola

The EXT Library is set of various useful classes, templates and macros that extend functionality provided by ISO C++ (ext sub-library), standard C and C++ library (lib), to abstract parts of Windows API (win) and access PE file resources (res).

Framework written in C language using OO concepts. Pretty similar to Java. This is gonna change your way of programming in C. Feel free to contact me at juanrb@hotmail.com.

C++ production ready implementation of Scott Seely's Simple SOAP RPC code. OS neutral, HTTP transport, XML validation, envelope parsing, RPC dispatching, extendable data types, fault generation and a extendable test suite useful for release validation. Now builds on newer versions of Linux.

OpenSource C++ libraries. Full list of classes and functions listed at yf-library.sourceforge.net

OpenBASIC is a modernized programming derived from the syntax of QBasic, QuickBasic, and FreeBASIC, yet has most (if not all) of the Object-Oriented features of C++, as well as the portability of that language coupled with Allegro for graphics routines.

Property/configuration mechanism for high-performance C++ applications. Similar to but more flexible than Java properties. Property settings provide type safety, expressive error messages and full-featured expressions. Based on the Lua language.

Spine provides a means of using inversion of control(dependency injection) techniques to create a multi tier application by using a generic model to instantiate java classes specified in configuration along a defined process flow.

apugg is an object-oriented plugin loading library written in pure C++. It is designed to be usable across platforms, and adding support for new styles of plugins is done by simply inheriting a library class.

libthrowable is a small library to ease error handling and debugging in C++.

A C++ UUID compliant to RFC 4122.

Web, Wap & iMode Java J2SE/J2EE Lightweight Framework and Tools

A set of platform independent utility and wrapperclasses in C++. This library contains amongst others a regex engine, hashtable and vectorclass, and a randomgenerator. SDLwrapperclasses for fonts and images, GUI, server and client and a httpclient.

A simple application logger class implementation based on C Plus Plus. -Supports Log file Rotation -Supports Split of Log files

Aquamarine is a Object Oriented language. The goal of this project is to provide a aquamarine to C++ compiler and a classes library.
