Bigloo is an implementation of the Scheme programming language. It relies on an optimizing compiler from Scheme to C. Bigloo enables connections between Scheme code and C code. It proposes many extensions to Scheme such as a regular parser compiler, an lalr parser compiler, pattern matching, an object layer, etc.
ccaudio2 is a simple, highly portable, stand-alone, C++-based framework for manipulation of audio data. Its goal is to be a C++ framework that is as useful as "audiofile" or "sndfile" is for C programming, and to cover various generic and useful manipulations of audio data as well as audio file access. A stand-alone audio processing command line tool is also provided to demonstrate library functionality. ccaudio2 compiles under Mac OS X, POSIX systems, and Win32 systems.
Coin is an implementation of Open Inventor. Open Inventor is the de facto standard API for retained-mode 3D graphics programming. Open Inventor has a highly extensible design, and has been designed to allow for rapid development of highly interactive 3D graphics applications in the fields of CAD, engineering, scientific computing, simulation, VRML, and visualization.
Common C++ is a highly portable C++ class library meant primarily for the development of portable threaded applications. Support is provided both for POSIX platforms and native builds under Win32. The goal is to provide a truly common C++ framework for writing portable threaded applications that do not require a huge amount of runtime overhead to support, and hence can make C++ and threads suitable even for the development of trivial servers and applications.
Common C++ RTP is an experimental threadsafe RTP stack for use with Common C++. It uses a service thread to both schedule outgoing packets and organize arriving packets. Queued lists of packets are maintained both for sending and receiving, and packet payloads can be mixed such as for passing RTP telephony events. Recent builds of GNU ccRTP are also available for building handheld softphone clients using Open Embedded.
