未绑定模块编译Ocaml游戏时发生事件错误

问题描述

Ocaml和我的新的试图从。我使用windows 7与ocaml版本4.00.0但是当我尝试使用下面的命令编译。我收到此错误

Am new to Ocaml and i was trying to compile the game mltetris from http://lambda-diode.com/software/ocaml/. I am using windows 7 with ocaml version 4.00.0 however when i try to compile using the command below. I get this error

C:\Users\WASSWA SAM\ocaml stuff\mltetris>ocamlc -pp camlp4o -o tetris.exe human.
ml game.ml play.ml tetris.ml tetris.mli
File "play.ml", line 21, characters 16-26:
Error: Unbound module Event

事件模块不是标准分发的一部分。我使用此命令检查库

Isn't the Event Module supposed to be part of the standard distribution. I checked the libraries using this command

缺少我不知道是什么问题。

What's missing I don't know what's wrong.

推荐答案

事件模块似乎是线程设施的一部分。手册说明：

The events module appears to be part of the threads facility. The manual says this:

   ocamlc -thread other options unix.cma threads.cma other files  
   ocamlopt -thread other options unix.cmxa threads.cmxa other files
