C/C++：VSCode配置C++开发环境【Windows系统】

 一、安装插件

1、安装C/C++插件

2、安装CMake、CMake插件

3、安装其他插件

3.1、Error Lens（错误提示）

 3.2、One Dark Pro（主题插件）

二、代码演示

1、main.c

#include 
 
int main()
{
    std::cout << "\nhello world\n" << std::endl;
    return 0;
}

2、CMakeLists.txt

参考CMake官网

 2.1 创建文件 CMakeLists.txt

在CMakeLists.txt文件中添加：

cmake_minimum_required(VERSION 3.10)
 
# set the project name
project(Tutorial)
 
# add the executable
add_executable(Tutorial tutorial.cxx)

2.2 Ctrl + P打开配置文件

2.3 VScode的Unable to determine what CMake generator to use问题处理

Unable to determine what CMake generator to use. Please install or configure a preferred generator, or update settings.json, your Kit configuration or PATH variable.

解决方案

• 检查当前根目录下（即你通过VSCode的打开文件夹功能打开的文件夹）是否存在以“.code-workspace”文件，如果不存在则如下面的操作创建此文件

然后在弹出来的文件保存管理窗口中直接点“保存”即可。

• 打开“.code-workspace”文件

{
	"folders": [
		{
			"path": "."
		}
	],
	"settings": {
		"files.associations": {
			"*.ejs": "html",
			"iostream": "cpp"
		},
		"cmake.generator": "MinGW Makefiles"
		
	}
}

改成这个样子即可（添加了划红线的语句，旨在告诉CMake你要用的generator姓甚名谁）

"cmake.generator": "MinGW Makefiles"

3、确保你的VScode至少同时拥有以下3个扩展

1. C/C++
2. CMake
3. CMake Tools

4、然后在工具栏点击CMake

三、VSCode窗口作用

1、选择“编译器”

2、编译
