I'm trying to build an OCaml project using ocaml build command which looks similar to

ocamlbuild -use-ocamlfind test.byte

Following error is observed.

Error: Unbound value String.lowercase_ascii. I have install Clang and i am using OCaml 4.07.0

The function String.lowercase_ascii was introduced in OCaml 4.03. You should check that you are really using OCaml 4.07 and not an earlier version.

    In particular, `ocamlfind ocamlc -v` will return the OCaml version used through `ocamlfind`. – gasche Jan 30 '19 at 15:34
