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.

Libiqxmlrpc is C++ object-oriented library that represents an XML-RPC solution for both client and server. It supports HTTP and HTTPS, both single-threaded and multi-threaded computation models on the server side, method interceptors, and other features.

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 X, 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.

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.

The CoreLibrary is a multiplatform object library for C++ (Linux, Win32, MacOSX, PocketPC). It provides many of the common objects found in Java (Strings, Threads, Collections, etc.) and has the ability to send objects across the network like CORBA.

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.

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

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.

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).

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.

This software like a Text Log File Reader.

A group of generic tools and containers for using in logical and mathematical terms. Lisp like type-safe n-Trees.

Simple and lightweight application framework for amiga compatible systems. Enables development of object oriented C++ applications running on amiganoid operating systems like AROS, AmigaOS 3.x, AmigaOS 4.x and Morphos 2.x.

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

Provides an easy to use, reusable, optimized, and portable suite of C++ classes. The framework takes away complexity by handling all low-level work, thus speeding initial development, resulting in fewer bugs, and lowering maintenance costs.

GWT is an flexible and object-oriented 2d game engine. It uses Code::Blocks and is based on SFML2 to give the ability to port your code to multiple platforms. With the integrated all-in-one tool for game resources it's possible to develop games in a short time. And it's open source! (license coming soon) Status: planning phase

https://github.com/jplevyak/ifa IFA, Iterative Flow Analysis is a combined data-flow and control flow analysis. It is capable of resolving the concrete types (as opposed to the nominal or declared types) and the interprocedural call graph for statically or dynamically typed programs.

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.

The Micro C++ Library (libmicxx) is a small set of portable and easy to use classes providing core features commonly used in modern applications. It is based completely on the Standard C++ Template Library (STL).
