ocaml Unix.system 调用 pdflatex

我在从已编译的 ocaml 应用程序 pdflatex 调用外部应用程序时遇到问题。我使用正确的字符串作为参数，当我从顶层运行它时，我得到了预期的结果，

Unix.system "pdflatex -interaction batchmode -output-directory res ALGO_GEN.tex";;

并且它生成了正确的输出，

从编译的应用程序中，日志表明，

*** (job aborted, no legal \end found)

它已经让我困惑了一段时间。我使用了来自 Unix 模块的其他系统调用以及其他命令行选项。我想知道是否有人可以就如何进行提供一些建议。该应用程序生成一些 tex 文档，需要将它们转换为 pdf。从顶层，调用它们列表上的映射可以正确生成 pdf；仅编译（字节代码）不起作用。

原文

I'm having a problem calling an outside application from a compiled ocaml application, pdflatex. I'm using the proper string as an argument, when I run it from the toplevel I get the expected results,

Unix.system "pdflatex -interaction batchmode -output-directory res ALGO_GEN.tex";;

And it generates the proper output,

From the compiled application, the log indicates that,

*** (job aborted, no legal \end found)

It has been confusing me for some time. I've used other system calls from the Unix module, and other command line options. I'm wondering if anyone can give some advice on how to proceed. The application generates a few tex documents, and they need to be converted to pdf. From the toplevel, calling a map over a list of them generates the pdfs properly; only compiled (byte code) does it not work.
