prolog interpreter on linux?

Question

I've decided to learn prolog. What's a good interpreter to use? Even better if it has a decent c/c++ ffi.

Answer 1

GNU Prolog sounds like a decent starting point.

Answer 2

I'd recommend GNU Prolog, because that seems to be the standard, but I've also heard good things about SWI-Prolog.

Answer 3

I personally use ECLiPSe.
