Latest stable version: 3.26.0
Release date: May 8, 2019
Requirements
Logtalk runs on any operating-system with a standards compliant modern Prolog compiler. The interface between Logtalk and a specific backend Prolog compiler is accomplished using a small adapter file. The Logtalk distribution includes adapter files for all supported Prolog compilers:
- B-Prolog 7.8 or later versions
- CxProlog 0.98.1 or later versions
- ECLiPSe 6.1#143 or later versions
- GNU Prolog 1.4.5 or later versions
- JIProlog 4.1.6.1 or later versions
- Lean Prolog 4.5.7 or later versions (experimental)
- Qu-Prolog 9.7 or later versions
- Quintus Prolog 3.3~3.5 (experimental)
- SICStus Prolog 4.1.0 or later versions
- SWI Prolog 6.6.0 or later versions
- XSB 3.8.0 or later versions
- YAP 6.3.4 or later versions
Legacy Logtalk versions (2.x) provide support for several other Prolog compilers, which are no longer supported due to lack of compliance with official and de facto standards.
Be sure to install the Prolog systems that you want to use as backend compilers before installing Logtalk. In general, it is recommended that you install the most recent versions of the Prolog systems.

instructions on how to customize and run Logtalk. For Windows users,
this information is also available from the Logtalk program group in
the Start Menu.
The following installers are available for the latest version:
macOS
Based on the MacPorts portfile. Installs
Logtalk on /opt/local/share/ with integration scripts for supported
Prolog compilers on /opt/local/bin. Creates an /Applications/Logtalk
folder with links to the installed files.

A MacPorts portfile is also available. Users
may simply type the command sudo port install logtalk (or
sudo port upgrade logtalk) in order to install (or upgrade) Logtalk.
Homebrew users may simply type the
command brew install logtalk (or brew upgrade logtalk) in order to
install (or upgrade) Logtalk. But do check first that the MacPorts
portfile and the Homebrew formula are up-to-date.
Linux
Installs Logtalk on /usr/local/share with integration scripts for
supported Prolog compilers on /usr/local/bin. Package installation from
the command-line is recommended.

Debian (e.g. Ubuntu)
Requires dpkg 1.15.0 or a later version. Installs Logtalk on
/usr/share with integration scripts for supported Prolog compilers on
/usr/bin. Package installation from the command-line is recommended.
logtalk_3.26.0-1_all.deb

Windows
Be sure to install a compatible Prolog compiler
before running the Logtalk installer. Creates a Logtalk program
group in the Start Menu with integration shortcuts for supported
Prolog compilers and shortcuts for the accessing the Logtalk
documentation. Can be used by both admin and non-admin users.

SWI-Prolog pack
Logtalk is also available as a SWI-Prolog pack. The
pack is handy for
deployment but not ideal for development, however, as all the
files in the distribution are buried in a relatively deep sub-directory.
The pack can be easily installed typing the query pack_install(logtalk)
at the top-level. Also available as a manual download.
