Exception thrown when trying to use JPL and YAP Prolog in OS X?

Looks like you have to set a special use-flag to support threading in swi-prolog.

Looks like you have to set a special use-flag to support threading in swi-prolog. Look here for more details: comments.gmane.org/gmane.comp.ai.prolog.....

Yes, I saw that some people related this problem with the logic engine not supporting multi threading. However adding multi threading support did not help (as I wrote in the question). Anyway, I am happy the problem is solved, if I get a clue of why it occured I will update it here.

Right now I think that maybe it was just related to a bug in the version of Yap I was using, but I am not really sure. – Sergio Nov 3 at 21:11.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
