Yes, the documentation for Mac anything is sad. I will try to contribute - once I get it working myself.
Actually,don’t have any issues with the installation of Prolog. I just can’t get it working with Eclipse and the PDT.
Currently, getting the console error
! org.cs3.prolog.connector.process.PrologProcessException: org.cs3.prolog.connector.process.PrologProcessStartException: Failed to start the Prolog process.
! The path to the Prolog executable is invalid.
I got this after going into Eclipse->Preferences->PDT->Prolog Process, and entering the path that works on Mac:
/Applications/SWI-Prolog.app/Contents/MacOS/swipl
I say “that works on mac” because this is what I have added to my $PATH, and I am able to launch SWI-Prolog from my terminal.
But it’s clearly not working for Eclipse.
It’s good to note that I get the same error whether I have this Preferences entry, or not. So, there is some other “path to executable” within eclipse that is not valid.
