a free (under GNU Lesser GPL) library which provides a uniform interface to a large number of hash algorithms. These algorithms can be used to compute checksums, message digests, and other signatures.
a free library providing windowing and widgets for graphics APIs / engines where such functionality is not natively available, or severely lacking. The library is object orientated, written in C++, and targeted at games developers who should be spending t
an open-source C++ library which strives to make C++ easier to use as a "high-level" language, and emphasizes programmer productivity over the fastest possible code.
C++ interface for the popular GUI library GTK+. Highlights include typesafe callbacks, widgets extensible via inheritance and a comprehensive set of widgets.
open source high performance realtime 3D engine written and usable in C++ and also available for .NET languages. It is completely cross-platform, using D3D, OpenGL and its own software renderer.
a high-level audio API. It can play Ogg Vorbis, MP3, FLAC, uncompressed WAV, AIFF, MOD, S3M, XM, and IT files. For audio output, Audiere supports DirectSound or WinMM in Windows, OSS on Linux and Cygwin, and SGI AL on IRIX
a simple alternative to the STL that includes multithreading and networking. `target audience' is developers of complex network daemons, robots or non-visual client/server applications of any kind.
a library of C++ classes which lets you do Lisp programming within your C++ program even without any additional preprocessing, without all those calling conventions etc. No macros have ever been used by InteLib (except those for conditional compile directives). (With a very funny licensing lol)
a multi-platform C++ GUI toolkit. It is a product of Troll Tech. It is supported on all major variants of Microsoft Windows and Unix/X Windows. (BEWARE OF THE LICENSE)
a toolkit for the development of massively online universes. It provides the base technologies and a set of development methodologies for the development of both client and server code.
a library of functions and a framework to interface with crypto algorithms provided by the calling application, built-in, or provided through shared libraries.
The Typesafe Callback Framework for C++. allows you to define signals and to connect those signals to any callback function, either global or a member function, regardless of whether it is static or virtual.
network programming library. It is designed to take the pain out of programming network communications applications, providing an easy to use and cross-platform interface.
