用Chapel的“编译线”编译C++

Question

我想在我的chapel库中包含一些C++代码，第一步是让Chapel编译器根据this page编译cpp。然而，我得到了一个奇怪的错误。我的.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 World\n");
}

但是当我运行compileline时，我得到一个错误

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

我感觉我在遵循文档，但我看不到我遗漏了什么。
