使用 Chapel 的 "compileline" 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。但是，我收到一个奇怪的错误。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 我得到一个错误

 `/Users/buddha/github/chapel/util/config/compileline --compile` hello.cpp 
In file included from hello.cpp:6:
In file included from /Library/Developer/CommandLineTools/usr/include/c++/v1/iostream:38:

我觉得我正在按照文档进行操作，但我没有看到我遗漏了什么。

Answer 1

您为 std::cout 添加了 <iostream>，但您使用的是 <cstdio> 的 printf。

基本上，您混合的不仅仅是 C++ 和 chapel，还有 C++ 和 C。

Answer 2

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++，其工作方式类似，但需要 C++ 编译器而不是 C 编译器。
