Latest stable version: 3.30.0
Release date: September 17, 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:

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.

Automatically generated installers for the latest git version can be download from AppVeyor.

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.
