Language::Prolog::Yaswi ======================= Language::Prolog::Yaswi provides a bidirectional interface between Perl and SWI-Prolog (http://www.swi-prolog.org/) INSTALLATION To install this module the SWI-Prolog executable "pl" has to be in the PATH or alternatively the PL environment variable can be used to select another executable name and location. Type the following: perl Makefile.PL # or 'PL=/path/to/my/swi-prolog/executable perl Makefile.PL' make make test make install pl.pl script should be copied to a place in the PATH (pl.pl is a wrapper to run Prolog with support for calling Perl). Both or none Perl and SWI-Prolog have to be compiled with thread support. Other configurations are not supported and the build process will refuse to make the module with them. Under Perl only the ithread model is supported. If you get SEGV errors when using the module try compiling the prolog library with --disable-segv-handling (and send me also a bug report!). BUGS Requires SWI-Prolog 5.6.x or newer Loading of prolog shared libraries doesn't work, this is due to a limitation on SWI-Prolog itself. The programing interface should not be considered stable, incompatibilities could be introduced in future releases. MS WINDOWS SUPPORT This module has been minimal tested under windows, it seems to work, and I plan to support it, but the primary development platform continues to be Linux/Unix. To make it work, the "bin" directory for your SWI-Prolog installation will have to be included in your PATH also at runtime (If you get an error telling about the lippl.dll being missing, try using 8 chars names in the PATH, i.e. C:\PROGRA~1\SWI-PR~1\BIN).
