The library(editline) is based on BSD libedit, providing command line editing for the terminal on Unix-like systems.

Consequences

The library(editline) is an alternative to library(readline), providing the same functionality based on the GNU readline library. The library(editline) provides some advantages:

• BSD license doesn't affect the licensing of SWI-Prolog
• Also provides editing for secondary consoles (interactor/0)
• Can be programmed in Prolog

The main disadvantage is that GNU readline is a much more powerful editor.

Solutions

Install the development package for libedit. This is available on many platforms.

Debian/Ubuntu

$ apt-get install libedit-dev

Red Hat/Fedora

$ yum install libedit-devel or $ dnf install libedit-devel

After installing the development library, re-install the system
