テストファイルでモジュールを使用する際に問題が発生しています。私はこの問題を再現した簡単なバージョンを作成しました。メイクファイル(Ocaml)でモジュールを使用する際に問題が発生する
(* person.ml *)
module Person = struct
type person = {name: string; age: int}
let create_person name age = {name=name; age=age}
end
(*makefile *)
test:
ocamlbuild -pkgs oUnit,yojson,str,ANSITerminal test.byte && ./test.byte
check:
bash checkenv.sh
clean:
ocamlbuild -clean
(* test.ml *)
open OUnit2
open Person
let person = create_person "john" 40
(* utop *)
#use "person.ml"
open Person
let person = create_person "john" 40
Output: val person : person = {name = "john"; age = 40}
(* when I type in "make" in the terminal *)
ocamlbuild -pkg oUnit test.byte && ./test.byte

File "test.ml", line 4, characters 13-26:
Error: Unbound value create_person
Command exited with code 2.
Hint: Recursive traversal of subdirectories was not enabled for this build,
as the working directory does not look like an ocamlbuild project (no
'_tags' or 'myocamlbuild.ml' file). If you have modules in subdirectories,
you should add the option "-r" or create an empty '_tags' file.
To enable recursive traversal for some subdirectories only, you can use the
following '_tags' file:
true: -traverse
<dir1> or <dir2>: traverse
