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这个页面编译 cpp 。但是，我遇到了一个奇怪的错误。我.cpp的是

/* 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");
}

但是当我运行时compileline出现错误

 `/Users/buddha/github/chapel/util/config/compileline --compile` hello.cpp 
In file included from hello.cpp:6:

我觉得我正在关注文档，但我看不到我缺少什么。

Chapel 1.17（尚未发布，但您可以尝试预发布的 master 分支）添加了util/config/compileline --compile-c++类似的工作方式，但需要 C++ 编译器而不是 C 编译器。

您正在包括<iostream>forstd::cout但您正在使用printffrom <cstdio>。

基本上，您不仅要混合 C++ 和 chapel，还要混合 C++ 和 C。
