I am a beginer of ocaml, when I build the example, follow the sample(ffi chapters), get following error. then I made a change in dune , it works; not sure if it is my env issue or something else. Thanks for the book

The book was out of date with how ctypes is now packaged and how it's invoked via Dune. Take another look!
