与教堂的"compileline"一起编译C++

我想在我的教堂库中包含一些C++代码，第一步是让教堂编译器根据此页面编译 cpp。但是，我遇到了一个奇怪的错误。 我.cpp是

/* Hello World program
* `/Users/buddha/github/chapel/util/config/compileline --compile` hello.cpp
* */
//#include<stdio.h>   // just fine
#include<iostream>  // gastro-intestinal distress...
int main()
{
printf("Hello Worldn");
}

但是当我运行compileline时，我收到一个错误

`/Users/buddha/github/chapel/util/config/compileline --compile` hello.cpp

我觉得我正在遵循文档，但我看不到我错过了什么。
