README.rpms

Installing rpms
===============

There are three Maxima binary rpms:
maxima, maxima-exec-cmucl, and maxima-xmaxima.

The maxima and maxima-exec-cmucl rpms must be installed together.

maxima-exec rpms for other Lisp versions can also be installed,
although you'll probably have to build them yourself.

The maxima-xmaxima rpm is optional. Xmaxima is a Maxima GUI.


Building rpms
=============

You can build rpm files from an unpacked tarball or Git checkout.

(0) Go to the Maxima directory.

    $ cd sandbox/maxima  # or whatever is your top-level maxima directory

(1) Set the version number.
    
    Open ./configure.ac and change the AC_INIT line.
    (This is the only way I know to change the version number.)

    Optionally -- open ./maxima.spec.in and increment the `Release' number.
    (This number is appended to the version number.)

(2) Select Lisp version.

    Open ./maxima.spec.in.

    Change all `%define enable_<whatever>' to `0'
    except for the selected Lisp; make that `1'.

    Change all `%define <whatever>_flags' to `--disable-<whatever>'
    except for the selected Lisp; make that `--enable-<whatever>'.

(3) Build rpms.

    $ make rpm
    
    The maxima.spec file that is generated during this process builds
    four binary rpms:
    maxima, maxima-emacs, maxima-xmaxima, and maxima-exec-<whatever>.
