FriCAS for Cygwin64 (portable)

FriCAS for Cygwin64

FriCAS is a general purpose computer algebra system with a strong focus on mathematical research and development of new algorithms. (details see Wikipedia). This project is about providing a fully functional version for Cygwin64 (portable) including Cygwin/X.
Windows 10+ users may want to use WSL instead of cygwin, however, a portable FriCAS for Windows might be of interest anyway.

Portable Cygwin Version

Most comfortable is the portable Cygwin version from MachinaCore. However, we recommend the prebuilt versions from AppVeyor instead of the older 1.2 releases.

Binary Releases (fricas)

There are binary releases for the current FriCAS version 1.3.3:

• fricas-1.3.3-x86_64-cygwin.tar.gz (install to /usr/local)
• ecl-16.1.3.tar.gz (required if you don't have ECL already)

and

• FriCAS_CygwinPortable_1.3.3.7z

FriCAS_CygwinPortable will run out of the box. See below how it goes.

Portable mode howto

1. Download FriCAS_CygwinPortable64_x.y.z.7z
2. Unpack anywhere (7z required)
3. Start CygwinPortable.exe

4. Use tray menu

5. X server

6. Cygwin terminal (mintty)

7. FriCAS (Hypedoc/Draw)

Do it yourself

Get the latest release of CygwinPortable from AppVeyor, then setup the suggested system cygwin/X (use 64bit). Or, one may even start from scratch:

git clone https://github.com/MachinaCore/CygwinPortable.git

Get devel tools

wget rawgit.com/transcode-open/apt-cyg/master/apt-cyg
install apt-cyg /bin

apt-cyg searchall gcc
apt-cyg install gcc-g++
...

or, better, use the menu/setup in the tray.

Get ECL (Lisp)

git clone https://gitlab.com/embeddable-common-lisp/ecl.git

Build it accordingly.

configure/make ECL 
apt-cyg install dos2unix
dos2unix /home/cygwin/ecl/src/bdwgc/install-sh
make install
$ ecl --version
ECL 16.1.3

Get and build FriCAS

wget https://sourceforge.net/projects/fricas/files/fricas/1.3.3/fricas-1.3.3-full.tar.bz2

Make FriCAS
===========
install all libs according to the INSTALL doc

kfp@NUC: ~/fricas-1.3.3
$ ./configure --with-lisp=ecl
$ make

Caveats and workarounds

Emacs interface will not work.

==========
Workaround
==========
cd contrib/emacs/
edit Makefile
Change:
 - default: efricas fricas-cpl.el
 + default: #efricas fricas-cpl.el

do make again ...
 
cp command.list fricas-1.3.3/target/x86_64-x-cygwin/lib/
make install
