问题
I suddenly started to get this error. I don't know how to diagnose or fix it. Am I supposed to grep through bar.ml and check every Big_int function against signature in Big_int.mli?
File "foo.ml", line 1, characters 0-1:
Error: The files /home/bar.cmi
and /usr/lib/ocaml/big_int.cmi make inconsistent assumptions
over interface Big_int
回答1:
Generally this message means that one .mli file has been recompiled recently but not the other. Since one of the .mli files is in your OCaml library, it might mean that you've upgraded your OCaml installation but haven't recompiled bar.mli since then.
What happens if you just recompile bar.mli?
回答2:
rm bar.cmi and try again; it looks like it was generated against a different version of Big_int.
