This folder contains a set of experimental examples illustrating how to use the CLP(FD) library distributed with SICStus Prolog 4.x with Logtalk.

The CLP(FD) library is loaded from the "loader.lgt" auxiliary loader file. This library must always be loaded prior to compilation of the individual example files.

In most cases, objects and categories containing CLP(FD) code must be compiled using the hook file ("sicstus_clpfd_hook.lgt") provided in this directory (see the "loader.lgt" file for an example). This hook file provides support for compilation of indexicals and overrides the meta- predicate directives of the CLP(FD) meta-predicates. When using the CLP(FD) labeling/2 enumeration predicate, the value/1 and variable/1 options are currently not supported.

Within objects and categories, is strongly recommended that you use the use_module/2 directive for the CLP(FD) module.
