ClioPatria can be downloaded using the GIT version control system only. Why? Because ClioPatria's package manager CPACK is based on GIT, so you need GIT anyway.
Step one, get GIT
You probably already have GIT. Otherwise go to its home.
Step two, get SWI-Prolog
In particular, binary packages provided by most Linux distributions are often too far behind. We advice to install the latest development version from source. It you run Ubuntu, we provide PPAs for releases.
Step three, download ClioPatria
With GIT installed, this is simple. Open a terminal in the right
directory and run the command below, which creates a directory
ClioPatria in the current directory.
% git clone https://github.com/ClioPatria/ClioPatria.git
