Question

我想在我的chapel libs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:

我觉得我正在遵循文档，但我不知道自己错过了什么。

Answer 1

Chapel 1.17（尚未发布，但您可以尝试预发布主分支）添加util/config/compileline --compile-c++，它的工作方式类似但是请求C ++编译器而不是C编译器。

Answer 2

您<iostream>包括std::cout，但您正在printf使用<cstdio>。

基本上你不只是混合C ++和教堂，还有C ++和C。

使用Chapel＆＃34; compileline＆＃34;编译C ++;
