Add to your prolog fial a directive :- discontiguous(listensToMusic/1). before the first clause. Daniel Bernardo Elayda a écrit : Hello, I'm trying to use this very simple Prolog testcase with Gnu Prolog v1.3.0: 1 listensToMusic(mia). 2 happy(yolanda). 3 playsAirGuitar(mia) :- listensToMusic(mia). 4 playsAirGuitar(yolanda) :- listensToMusic(yolanda). 5 listensToMusic(yolanda):- happy(yolanda). When the above code is loaded(w/o the line numbers), the interpreter says: | ?- [kb2]. compiling /home/captain/Junk/kb2.pl for byte code... /home/captain/Junk/kb2.pl:5: warning: discontiguous predicate listensToMusic/1 - clause ignored /home/captain/Junk/kb2.pl compiled, 5 lines read - 729 bytes written, 6 ms And if one runs the query playsAirGuitar(yolanda), the knowledge base did ignore clause number 5. What is wrong with line number 5? This same testcase with other versions of Prolog is processed correctly; clause number 5 isn't ignored. tia, Bernie -- Ce message a été vérifié par MailScanner pour des virus ou des polluriels et rien de suspect n'a été trouvé. ---------- _______________________________________________ Users-prolog mailing list [email protected] http://lists.gnu.org/mailman/listinfo/users-prolog -- Ce message a été vérifié par MailScanner pour des virus ou des polluriels et rien de suspect n'a été trouvé. _______________________________________________ Users-prolog mailing list [email protected] http://lists.gnu.org/mailman/listinfo/users-prolog
