From Gambit wiki
See the Scheme page for documentation on Scheme in general.
Some prebuilt distributions are available.
Building Gambit from Source
To build Gambit from source, one must first run the configure script, which has a number of important options.
There are various make targets of which you should be aware.
Packages, modules, libraries and driving systems
The Snow package system
Snow is a package system for R4RS and R5RS Scheme. Nearly all Snow packages run on Gambit. Users can simply download and install existing packages. For those who want to develop new packages, Snow has its own documentation.
Black Hole module system
Black Hole is a module system for incremental development and easily sharing code. It is bundled with a set of general purpose libraries.
The Scheme community has accumulated a set of common libraries and conventions called Scheme Requests for Implementation, publicly collected on srfi.schemers.org.
Snow as well as Black Hole feature certain SRFI:s. Also, there are SRFI:s that remain to be ported to Gambit.
There is an informal listing of sourcecode on the Dumping Grounds.
Gambit provides a powerful development environment through Emacs.
Termite is an Erlang-like distributed programming system written in Scheme.
Distributed computing hot right now, and Termite has been noticed in blogs and elsewhere.
Termite depends on specific features of Gambit, and at one time or another the Termite source code has been distributed with Gambit, so we point to the Termite web site from here.
People who want to contribute to Gambit development will need to learn something about how the Gambit-C runtime and compiler are organized. While we intend that source code documentation be included in the source itself (currently there is very little documentation), we intend that descriptions of program design or algorithms used in the runtime and compiler could be included on the Internal Documentation page.
Working with External Libraries
With Gambit's C FFI (Foreign Function Interface), one can easily use standard C and C++ libraries with your code; this wiki has some examples of and practices on using Gambit with external libraries. See Using Gambit with External Libraries.
See the Debugging page.
