ELENA is a general-purpose, pure object-oriented language with late binding. It promotes more object-oriented program design, reusable and more standardized code. The package includes compiler, IDE, ELENA libraries and samples

Libthreadar is a C++ library providing an abstracted set of C++ *classes* to manipulate threads in a very simple and efficient way from your C++ code. It also handles exceptions thrown from a thread and propagated to another one, when the later is calling the thread::join() method. This let one manage exceptions as simply as it is in C++ single threaded context. Additionally, all the related objects around multi-threading (mutex, semaphore, ...) are provided, under easy to use and independent C++ classes. Other more advanced classes ease the information exchange between threads like scattering and gathering a collection of objects between many threads, or asynchonous buffered information exchanges between two threads. All these C++ classes are easy to use and fully documented

Loglan'82 is a programming language conceived for object and distributed programming. It has many features that make Loglan'82 a tool surpassing other programming languages: * It enjoys a unique safe and efficient system of managing objects, see [[Safe dealocation]], * It offers modules of classes (__class__), moreover it allows to declare modules of cooperating objects i.e. **coroutines** and modules of threads ('''process'''). One can create not only objects of classes, but also objects of coroutines with their ''fibres'' and objects of processes, aka agents with their *threads*. * Virtual machines of Loglan may connect (through internet) in a virtual, multiprocesorr computer.This allows to distribute a computation of a program between processors in a controlled way. * Objects of processes (agents) can be alocated on different nodes of a network of virtual machines or on the same machine.

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.

FortWrap is a python script that parses Fortran 90/95/200X source files and generates wrapper code in the form of C++ classes. FortWrap is intended to be used with object oriented Fortran code that makes use of Fortran derived types. Project has moved to: https://github.com/mcfarljm/fortwrap

Reality Factory 2 is a next-generation game authoring suite. It combines a flexible, fully scripted game development environment powered by Python with the Ogre3D engine, and supports all major desktop operating systems.

Object oriented reusable software classes designed to be used to construct larger software projects developed in multiple software languages.

A bignum library written in the C++ programming language as templates. It provides standard mathematical operations like add, sub, mul, div, pow etc. with the big integer and big floating point numbers.

C++ Grid/Table control with rich set of features. Now implemented in pure WinAPI. Also useful for MFC projects (via CWnd wrapper).

Robust, Lightweight, Cross-platform, Template Software. STLSoft is a collection of STL and standard library extensions, and facades over operating-system and 3rd-party APIs.

The Data Structure & Algorithm Library (DSAL) is a library of classical data structure and algorithm.

AO-RTOS is a pure object-oriented small footprint real-time operating system for embedded devices. The project is using Active Object (or Actor) concurrency model and finite state machine (FSM) design template as implementation base.

NOTE: PythonQt has been moved to https://github.com/MeVisLab/pythonqt PythonQt is a dynamic and lightweight script binding of the Qt framework to the Python language. It can be easily embedded into Qt applications and makes any QObject derived object scriptable via Python without the need of wrapper code generation.

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.

TMV is a comprehensive linear algebra library which uses operator overloading, views & delayed evaluation to simplify matrix and vector expressions in C++. It is well documented and can optionally call optimized BLAS/LAPACK for faster execution times

Small footprint C++ library to extract an XPath 1.0 expression from an XML tree. Uses the TinyXML project to parse XML trees and store intermediate results. Runs on any platform. Optional use of STL. Overhead less than 100KB, including TinyXML.

Sqrat is a C++ library for Squirrel that facilitates exposing classes and other native functionality to Squirrel scripts. It models the underlying Squirrel API closely to give access to a wider range of functionality than other binding libraries. In addition to the binding library, Sqrat features a threading library and a module import library.

A general purpose, object-oriented script language that compiles into code for a register based virtual machine. The language is quite similar to object-oriented high-level languages like Java and C#. The library is entirely self-sufficient and ANSI C compliant. It's main purpose is to be embedded in any application to allow automation of that application through scripting. An integrated C++ binding code generator allows you to create bindings for your application's classes in seconds. The integrated HTML documentation generator allows you to create documentation for your native bindings in seconds. The project is released under the zlib/libpng license. It has been in development for over 10 years and offers some powerful features. Extensive information, documentation, articles and code examples can be found at the developer blog.

PyKCS11: a complete PKCS#11 wrapper for Python, created using the SWIG compiler. API documentation: http://pkcs11wrap.sourceforge.net/api/

CLAW is a C++ Library providing various tools in different domains, like a Tweener framework, Bézier curves manipulation, a map with multiple value types, a binary search tree container implemented as an AVL and an implementation of the sockets as std::stream. The library also includes a set of classes to easily load and write png, jpeg, gif files and other image formats. Finally, a part of the library is devoted to artificial intelligence in games and includes a generic alpha-beta algorithm. Each module is provided with an example program.

wsdlpull is an efficient and powerful command line utility for dynamic inspection and invocation of WSDL web services.It provides a C++ library with dynamic WSDL invocation API,WSDL parser,Schema parser and Validator and an xmlpull Parser/Serializer.
