Quickly getting a working copy of Semigroups

The following script should clone and fully compile GAP, the master branch of the Semigroups package and all of its dependencies. It's verified working on Debian Testing, as of 2016-05-29, and Mac OS 11.3.1, as of 2021-06-16. It will clone the master branch (change master to your preferred branch if you want a different one), which contains an interface to the C++ library libsemigroups.

Some software is required on the target computer for everything to work. This includes: git, autoconf, curl, GMP, a C/C++ compiler, graphviz, LaTeX, libtool, and make.

If you're using a Linux distribution with APT (e.g. Debian/Ubuntu/Mint) then the following command should automatically install all the software you need (texlive-full might take a while):

sudo apt-get install autoconf build-essential curl git graphviz libtool libgmp-dev texlive-full

If you're using a Mac, and have brew installed, then this command should install a lot of what you need (though maybe not everything):

brew install git autoconf automake curl GMP graphviz libtool

Once you have all the right software installed, run this script or copy and paste the following lines into your terminal:

#!/bin/bash
set -e

GAP_BRANCH=master
LIBSEMIGROUPS_BRANCH=v1.3.7
GAPDOC=1.6.4
