win 10 下 使用vscode 應用WSL +cmake 做C/C++開發調試

安裝WSL

啓動Linux 子系統功能

進制控制面板->程序和功能， 將適用於Linux的Windows子系統勾選。

安裝 Windows Terminal

在 Microsoft Store市場上搜索 WSL 安裝 Terminal

安裝WSL

在 Microsoft Store市場上搜索 WSL 安裝 Ubuntu 18.04 LTS

如何啓動 Ubuntu?

1. 在 cmd/powershell中輸入 bash回車即可進入linux子系統
2. 直接在terminal下拉中選擇

如果覺得默認的終端主題不好看可以自行安裝 oh my zsh

安裝 編譯工具鏈

sudo apt update # 更新軟件包
sudo apt install build-essential #安裝build-essential軟件包
sudo apt install gdb # 
sudo apt install cmake

等待安裝完成，之後查看安裝結果

cmake --version
gcc -v
g++ -v

安裝vscode

vscode的不說，宇宙第一編輯器，傳送門 https://code.visualstudio.com/

安裝vscode插件

1. Rmote - WSL
2. C/C++ IntelliSense
3. Beautify
4. Rainbow Brackets
5. cmake

配置C/C++調試參數

先寫一個簡單的演示項目工程

test.h

#ifndef _TEST_H_
#define _TEST_H_

int add(int a, int b);

#endif

test.c

#include "test.h"

int add(int a, int b)
{
  return a + b;
}

main.c

#include "test.h"
#include <stdio.h>
#include <stdlib.h>

int main()
{
    int a = 88;
    int b = 12;
    int c = add(a, b);
    printf("結果是%d\n", c);
    return 0;
}

CMakeLists.txt

cmake_minimum_required(VERSION 2.8)
project(demo)

add_definitions("-Wall -g -Wno-unknown-warning-option"
        " -Wno-format-extra-args -Wno-format -Wno-pragmas"
        " -Wno-incompatible-pointer-types")

add_executable(1
  src/main.c
  src/test.c
 
)

在.vscode目錄下添加tasks.json

{
   "tasks": [
       {
           // 清空編譯
           "type": "shell",
           "label": "rebuild",
           "command": "cd build; rm -rf *; cmake .. ; make",
           "group": {
               "kind": "build",
               "isDefault": true
           }, 
              
       },
       {
           // 增量編譯 
           "type": "shell",
           "label": "build",
           "command": "cd build; make",
           "group": {
               "kind": "build",
               "isDefault": true
           }, 
       }
   ],
   "version": "2.0.0"
}

在launch.json中添加 調試啓動配置

1. "program":"配置調試的應用路徑"
2. "preLanchTask":"配置Lanch前先執行的任務，可以先執行make"

           ],
           "preLaunchTask": "build"
       },

       {

               }
           ]
           ,
           "preLaunchTask": "rebuild"
       }


   ]
}

開始調試

1. 設置斷點，點擊調試開關啓動調試
