在Vscode中使用gdb调试程序

在Vscode中使用gdb调试程序

  • 1 创建launch.json文件
    • l a u n c h . j s o n \textcolor{red}{launch.json} launch.json
  • 2 创建tasks.json文件
    • t a s k s . j s o n \textcolor {red} {tasks.json} tasks.json

详情参考官方文档

set(CMAKE_BUILD_TYPE Debug)		# 首先要在CMakeList.txt中设置dubug模式

1 创建launch.json文件

  调试多个程序和调试一个程序是一样的道理,只需要后面把两个文件compounds

        }
      ]
}  

2 创建tasks.json文件

t a s k s . j s o n \textcolor {red} {tasks.json} tasks.json

  这个文件是通用的,直接复制粘贴即可。这个文件主要为了编译代码,所以如果不对代码修改,其实也可以不加这个文件。

{
    "options": {
        "cwd": "${workspaceFolder}/build"
    },
    "tasks": [
        {
            "type": "shell",      // 相当于对整个文件进行编译的步骤     此处代表cmake ..
            "label": "cmake",
            "command": "cmake",
            "args": [
                ".."
            ]
        },
        {
            "label": "make",     // 此处代表make
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "command": "make",
            "args": []
        },
        {
            "label": "Build",   		// label表示编译的文件存放的位置,要求与launch.json中的preLaunchTask相同
            "dependsOrder": "sequence",   
            "dependsOn":["cmake","make"]   // 此处表示联合两条指令
        }
    ],
    "version": "2.0.0"
}
