MIT/GNU Scheme
![[Image: Lambda shield]](lambda.png)
MIT/GNU Scheme is an implementation of the Scheme programming language, providing an interpreter, compiler, source-code debugger, integrated Emacs-like editor, and a large runtime library. MIT/GNU Scheme is best suited to programming large applications with a rapid development cycle.
Release status and future plans
Stable |
---|
10.1.5 |
The releases provide binaries that run on i386 and x86-64 machines under the following operating systems: GNU/Linux and OS X. We additionally provide binaries for selected other architectures and systems, depending on the hardware and software that is available to us. We no longer support OS/2, DOS, or Windows.
Recent release notes are here.
Other potential projects can be found on the tasks page.
Download
MIT/GNU Scheme is available in binary form for a variety of systems. Note that most problems unpacking or installing this software are due to corrupted downloads, so please check the downloaded file for a correct MD5 checksum before submitting a bug report. Each distribution below has its own list of MD5 checksums.
File | Arch | Instructions | Notes |
---|---|---|---|
Unix binary | i386 | unix installation | |
Unix binary | x86-64 | unix installation | |
macOS binary | x86-64 | Compiled on macOS 10.13. | |
Portable SVM | (any) | unix installation | For use on any 64-bit unix system. |
Source (.tar.gz) | For unix systems; uses linefeeds as line delimiters. | ||

Older versions can be downloaded here.
Note that you cannot build a working system from the source unless you have a working MIT/GNU Scheme compiler to do the compilation. (This doesn't apply to the portable C source, which requires only a C compiler.) This means that if the above binaries don't work on your system, it is pointless to try building a custom set of binaries from the source code.
