有没有办法在 OCaml 沙丘中用连字符声明可执行文件？

Question

我正在使用 dune 设置一个演示项目，并希望将可执行文件命名为“hello-world.exe”而不是“hello_world”。如果我尝试构建项目，我会收到编译器错误。如何在文件名中声明带有连字符的可执行文件？

我正在使用 dune 1.9.3 和 OCaml 4.05.0。

沙丘：

(executable
 (name hello-world))

你好世界.ml

let () = print_endline "Hello, World!"

编译错误

$ dune build hello-world.exe

Answer 1

您需要禁用警告24：

(executable (name hello-world) (flags (:standard -w -24)))

或者只是

(executable (name hello-world) (flags (:standard -warn-error -24)))

如果您希望保留警告
