===================================

FriCAS0 -- a pure Common Lisp build

===================================

Build

-----

Tested so far::

    

    git clone https://github.com/nilqed/fricas0.git

    cd fricas0

    

    ecl -load fricas

    sbcl --load fricas

    java -jar abcl.jar --load fricas

Note: for SBCL, you can compile the ``interp`` directory before loading fricas.

This can improve speed greatly.

    sbcl --load lisp/load-lisp.lisp --load lisp/compile-interp.lisp --eval "(exit)"

    

The first time - when the interpreter is loaded - you have to compile

the *algebra*::

    

    )lisp (load "lisp/compile-algebra.lisp")

    

Since each of the above mentioned Common Lisp flavours compile to a different

format (``ecl -> .fas, sbcl -> .fasl, abcl -> .abcl``), you may use the same

``fricas0`` folder simultaneously.

.. note::

    

    Everything here is still considered experimental and **not** ready for

    production. The goal is to provide a functional version of ``FriCAS`` 

    (i.e. no gui) with minimal build requirements, e.g. allowing usage as a

    library in other systems as platform independent as possible.

    

Comments

--------

On Ubuntu ``ECL 15.3.7`` is provided via ``apt install ecl``. You will

also need ``apt install libffi-dev``, otherwise it won't compile. This

version is quite outdated and it might be advisable to compile the

latest version by yourself. The same holds for Android (arm). 

On Android ECL works well under `GNURoot`_. You certainly want to install

``sshd`` in order to work from your desktop (use PuTTy on Windows).

.. _GNURoot: https://play.google.com/store/apps/details?id=com.gnuroot.debian&hl=en

A bug in ABCL 1.5 inhibits the compilation of three algebra files 

(e.g. ``polyvec.lsp``). At the moment these files are exluded by

``#+:ABCL`` pragmas in ``compile-algebra.lisp``.

GNU CLISP 2.49+ (2010-07-17) was also (+) tested on Cygwin64. 

The current version is based on the official release `FriCAS`_ tarball

(version 1.3.2). The files in ``algebra`` are from the

``pre-generated`` folder (**unchanged**) and the ones in ``interp`` are

translations from the ``boot`` code (original as well). Generally, no

original files were changed, only the new ``lisp`` files ``fricas``, 

``fricas-abcl``, ``interp`` and ``compile-algebra`` are newly added.

.. warning:: **Windows users**: 

    If you encounter errors while loading the interpreter with a native

    CL (e.g. SBCL) it is probably caused by wrong line endings (checkout). 

    See

    https://help.github.com/articles/dealing-with-line-endings/

    

    Ensure: git config core.autocrlf = true

    

    A ``.gitatributes`` was added to prevent the change of the ``*.daase``

    and ``*.msgs`` files.

 

    **Initfile**: It was reported by ``oldk1331`` that certain entries in 

    ``~/.fricas.input`` may cause errors in ``SBCL``. He `suggests`_ to 

    set ``export FRICAS_INITFILE=""``.
