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.

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.

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.

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.

Prop is a pattern matching language based on C++. It implements algebraic datatypes, pattern matching and rewriting, and generates C++ code as output.

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

dbus-cxx is a C++ wrapper for dbus. It exposes the C API to allow direct manipulation and relies on sigc++ to provide an OO interface. Also included is dbus-cxx-xml2cpp to generate proxy and adapter interfaces from DBus XML introspection-like documents.

SOF (Service Oriented Framework) helps software developers to develop component based software.

A well designed and portable SQLite wrapper library for C++ You're welcome to make suggestions for design improvements. Feature requests are welcome too.

ClassBuilder is freeware CASE tool targeted at the C++ developer, running on Win2K/XP/Vista/7. It lets you create, manipulate and navigate classes, class relations, class members and class methods at a high level of abstraction through a graphical user interface

SmartDB is an object oriented approach towards integrating SQLite database, like ms ado object, for C++/MFC projects. It acts as a wrapper for SQLite. You can open SQLite database into your program with just 3 lines of code. full source code available.

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.

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.

Aswang is a lightweight and flexible C++ class framework meant to make windows GUI development easier and faster without the imposition of bloated libraries or any particular visual style.

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.

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.

QConsole is a custom Qt widget implementing a standard console to be inherited to support a specific scripting language or shell, and then embedded in any Qt application. As example, a Tcl console (QtclConsole) is provided for use in EDA applications
