Module 编译Ocaml游戏时出现未绑定模块事件错误

我是Ocaml新手，我正试图从中编译俄罗斯方块游戏。我正在使用ocaml版本4.00.0的Windows7，但是当我尝试使用下面的命令进行编译时。我得到这个错误

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

事件模块不应该是标准发行版的一部分吗。我使用这个命令检查了库

缺少什么我不知道是什么问题。

是的，

事件

是标准库的一部分

在我的机器上，以下命令序列正在工作：

ocamlopt -thread  -c human.ml
ocamlopt -thread  -c game.ml
ocamlopt -thread  -c tetris.ml
ocamlopt -thread  -c play.ml
ocamlopt -thread  unix.cmxa threads.cmxa graphics.cmxa human.cmx game.cmx tetris.cmx play.cmx   -o tetris.opt

与手动编译每个文件（在本例中可能有效）不同，更长期的方法是使用提供的Makefile，只需发出命令

make

（上述命令实际上是

make

运行的命令）。

似乎您在Windows下，在这种情况下，一个选项是安装Cygwin，它提供了一个版本的

make

。Cygwin本身就是一个完整的章节，请在开始之前阅读它。

事件模块似乎是threads工具的一部分。手册上说：

使用系统线程的程序必须按如下方式链接：

我现在在尝试您的代码时出错。”i686-w64-mingw32-as“未被识别为内部或外部命令、可操作程序或批处理文件。文件“human.ml”，第1行：错误：汇编器错误，在文件C:\Users\WASSWA~1\AppData\Local\Temp\camlasmcb1c14中保留输入。sLet首先尝试保持与以前的尝试接近。我会尝试将所需选项和编译的模块添加到几乎正常工作的命令中：try

ocamlc-custom-thread-pp camlp4o-o tetris.exe unix.cma threads.cma graphics.cma human.ml game.ml tetris.mli tetris.ml play.ml

（顺便说一句，为什么要添加

-pp camlp4o

？）。
