## 一、安装插件 ##

### 1、安装C/C++插件 ###

### 2、安装CMake、CMake插件 ###

### ![1a76bd98b0174c148d35bd90ffbca3ee.png][] ###

### 3、安装其他插件 ###

#### 3.1、Error Lens（错误提示） ####

#### 3.2、One Dark Pro（主题插件） ####

![cb0bcb5b1385486fa0758027aa8f3928.png][]

## 二、代码演示 ##

### 1、main.c ###

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

### 2、CMakeLists.txt ###

参考CMake官网

![c6a96ecf46c044c6b4562fd74d1938cb.png][]

#### 2.1 创建文件 CMakeLists.txt ####

![acb8f2f402dc4482955d45d306465a2e.png][]

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)

![5c31faebe6c4467381c6d8f810ff2058.png][]

#### 2.2 Ctrl + P打开配置文件 ####

![6e4314be832f45f492a75d6c88a9f694.png][]

#### 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][Link 1]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

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBATFlaODMy_size_20_color_FFFFFF_t_70_g_se_x_16]

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

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBATFlaODMy_size_20_color_FFFFFF_t_70_g_se_x_16 1]

{
    	"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）

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBATFlaODMy_size_20_color_FFFFFF_t_70_g_se_x_16 2]

"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 ###
