Maxima is a descendant of DOE Macsyma, which had its origins in the late 1960s at MIT. It is the only system based on that effort still publicly available and with an active user community, thanks to its open source nature. Macsyma was the first of a new breed of computer algebra systems, leading the way for programs such as Maple and Mathematica. This particular variant of Macsyma was maintained by William Schelter from 1982 until he passed away in 2001. In 1998 he obtained permission to release the source code under GPL. It was his efforts and skill which have made the survival of Maxima possible, and we are very grateful to him for volunteering his time and skill to keep the original Macsyma code alive and well. Since his passing a group of users and developers has formed to keep Maxima alive and kicking. Maxima itself is reasonably feature complete at this stage, with abilities such as symbolic integration, 3D plotting, and an ODE solver, but there is a lot of work yet to be done in terms of bug fixing, cleanup, and documentation. This is not to say there will be no new features, but there is much work to be done before that stage will be reached, and for now new features are not likely to be our focus.

You can choose among the different downloading options in the Download page, which will redirect to the appropriate sourceforge.net download page. The code is available as prepackaged Windows and Linux binaries as well as in source code form.
Since William Schelter’s passing a group of users and developers has formed to keep Maxima under active development. There are currently 25 developers who can make changes to the source code. To get in touch with them, the preferred channel is the mailing list

The system developed at MIT was called Macsyma (although the nicknames MACSYM and MAXIMA were sometimes used since filenames were limited to six uppercase-only characters in sixbit character code).
Symbolics licensed Macsyma from M.I.T. and registered ”Macsyma” as a trademark at some point (presumably with M.I.T.’s permission).
When Macsyma source ceased to be freely available, pressure was put on M.I.T. (mostly by Fateman) to transfer the code which had been developed largely with Department of Energy (DOE) funding to the DOE, which then released it to others under certain conditions.
That codebase was called DOE Macsyma. I don’t know what legal rights the DOE had to the name Macsyma as opposed to the codebase, but presumably the non-commercial users of DOE Macsyma wanted to avoid any legal wrangling around the name, and started using the name Maxima at some point (but I don’t know when that was).
So the short answer as I understand it is that Maxima is simply the most recent name for the branch that started under the name DOE Macsyma.
We suggest something like
Maxima.sourceforge.net. Maxima, a Computer Algebra System.
Version 5.30.0 (2013). http://maxima.sourceforge.net/
(or replace the version number and release year, if you are using a different version).
If you use Bibtex for your citations, we recommend that you add the following entry in your bibtex database:
@ELECTRONIC{maxima,
author = {Maxima},
year = {2013},
title = {Maxima, a Computer Algebra System. Version 5.30.0},
address = {http://maxima.sourceforge.net/},
url = {http://maxima.sourceforge.net/},
owner = {maxima},
timestamp = {2013.04.03}
}
Clisp, CMUCL, Scieneer Common Lisp (SCL), GCL (ANSI-enabled only) and SBCL can compile and execute Maxima. Allegro Common Lisp, OpenMCL and ECL might also work, but have not
been fully tested. Ports to other ANSI lisps should be straightforward and are welcome; please contact the developers if you are interested in working on a port.
See also the Lisp Implementations page.
You must install at least two rpms, maxima and maxima_exec. Go back to the SourceForge file manager and download a maxima-exec package and install that at the same time as the maxima package.
The Maxima RPMs were created on a specific Linux system. Other systems have different versions of various libraries. To install Maxima, the library versions must be the same.
You might be able to find rpms for your specific Linux version via the Maxima ports page.
You can recompile Maxima on your system. The rpms created that way have the right dependencies for your system.
To recompile Maxima, you need a Lisp implementation. I’ll recommend Clisp.
Once you have Clisp installed, download the Maxima src.rpm from the SF file manager. Unpack it and launch rpmbuild to create the rpm files:
$ sudo rpm -ih maxima-5.9.3.src.rpm
$ cd /usr/src/local # or whereever it is that rpm puts the source code
$ sudo rpmbuild -bb SPECS/maxima.spec
Then install the rpm files which were created in /usr/src/local/RPMS
.
You almost certainly need superuser privileges to write files to /usr/src/local
, hence the use of sudo. Perhaps you can get your friendly system administrator to handle it.
If you create RPMs, we can host them in the Sourceforge file manager; it would be helpful to anyone running the same Linux flavor.
The installation notes at http://maxima.sourceforge.net/download.html say a little bit more about rebuilding Maxima. In particular, follow the links to README.lisps and README.rpms.
C:\Program Files\Maxima-5.10.0\lib\maxima\5.10.0\binary-gcl\maxima.exe
in the list of DEP exceptions (Control Panel → System → Advanced → Performance → DEP)/etc/hosts
fileMake sure there is an entry that matches: 127.0.0.1 localhost
, otherwise wxmaxima and/or xmaxima will be unable to resolve "localhost" to a valid IP and then fail with "maxima terminated".
Probably your best bet is to report this problem on the wxMaxima user forum.
There are reports that wxMaxima does not work if Maxima is compiled with clisp or sbcl. If you are using one of those Lisp versions, you might want to try compiling Maxima with cmucl.
