Mac M1 with Vscode C++ environment

---

Preface

提示：本教程默认电脑安装Vscode 和 clang++

About whether clang++ is installed on the computer

Keyboard command + space and enter ter in the search box to select the terminal.

clang++ --version

The following figure appears and clang++ is installed locally.

---

1. Open VSCode and create a new folder

Create three folders in the root directory

• target stores compiled files
• src stores source code, that is, .cpp suffix file
• inc stores header files, which are files with .h suffix.

提示: 目录结构一定建立要正确

2. Install the plug-in

• Install and search for C/C++ as shown in the figure

• Install code runner

• Install CodeLLDB

3. Generate configuration files

• Create hello.cpp file under src
  
• Paste the following code in hello.cpp

#include <iostream>
using namespace std;

int main()
{
    
    

    cout<<"hello world"<<endl;
    return 0;
} 

• Generate task.json

1. Click the title button

2. Click clang++ to generate the active file.

3. You will create the .vscode file yourself to generate task.json.

Modify the task.json parameters.主要能够编译多文件 也就能够引入自定义头文件

Before modification

After modification

"-g",
"${fileDirname}/*.cpp",
"-o",
"${workspaceFolder}/target/${fileBasenameNoExtension}"

• Generate launch.json file

1. Click as shown in the picture
   
   to modify launch.json

"program": "${workspaceFolder}/${fileBasenameNoExtension}",

• Create c_cpp_properties.json.
  Press shaift + command + p (⇧⌘P) and click Edit Con...
  

• Set the code runner
  to create settings.json in .vacode

{
    
    
    "C_Cpp.errorSquiggles": "disabled",
    "files.associations": {
    
    
        "__locale": "c",
        "__string": "c",
        "string": "c",
        "string_view": "c",
        "cstring": "c",
        "locale": "c",
        "max.h": "c",
        "ostream": "cpp"
    },
    "code-runner.runInTerminal": false
}

Then set it up as shown in the figure


覆盖掉原来 cpp

"cpp": "cd $dir && g++ *.cpp -o $workspaceRoot/target/$fileNameWithoutExt && $workspaceRoot/target/$fileNameWithoutExt",

At this point, all configurations are completed. Next, run

Four, run

• Run the code you just pasted in hello.cpp, right-click -> RunCode

这里需要注意 结果 输出 这个不能写也就是程序有输入代码不可以 如果要输入东西 在 .vscode -> settings.json 修改 "code-runner.runInTerminal": true 即可

Test custom header files

• Create the swap.h file in the inc folder

#include <iostream>
using namespace std;

void swap(int a,int b);

• Create swap.cpp under src

#include "../inc/swap.h"
void swap(int a,int b){
    
    
    int temp = a;
    a = b;
    b = temp;
    cout << "a = " << a << endl;
    cout << "b = " << b << endl;
}

• Modify hello.cpp

#include <iostream>
#include "../inc/swap.h"
using namespace std;


int main()
{
    
    
    cout << "hello" << endl;
    int a = 10;
    int b = 20;
    swap(a,b);
}

Right click and run

Test multi-file debugging

Finally came in

注意: 如果你同一目录下 多个 .c / .cpp文件里都有 main函数 / std命名空间 要单独建立文件夹里面放目标文件 如图 (这里c截图演示)

Summarize

OK, you're done. If it helps you, please give it a like. Thank you.
