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。
Chapel 1.17(尚未发布,但您可以尝试预发布主分支)添加了util/config/compileline --compile-c++
,其工作原理类似,但需要C++编译器而不是 C 编译器。
您包含<iostream>
用于std::cout
但您使用的是<cstdio>
中的printf
。
基本上,你不仅混合了C++和教堂,还混合了C++和C。
