launch文件

{
        // 使用 IntelliSense 了解相关属性。 
        // 悬停以查看现有属性的描述。

        "version": "0.2.0",
        "configurations": [
            {
                "name": "g++ - 生成和调试活动文件",
                "type": "cppdbg",
                "request": "launch",
                "program": "${workspaceFolder}/build/pcl_test",
                "args": [],
                "stopAtEntry": false,
                "cwd": "${workspaceFolder}",
                "environment": [],
                "externalConsole": false,
                "MIMode": "gdb",
                "setupCommands": [
                    {
                        "description": "为 gdb 启用整齐打印",
                        "text": "-enable-pretty-printing",
                        "ignoreFailures": true
                    },
                    {
                        "description": "将反汇编风格设置为 Intel",
                        "text": "-gdb-set disassembly-flavor intel",
                        "ignoreFailures": true
                    }
                ],
                "preLaunchTask": "Build",
                "miDebuggerPath": "/usr/bin/gdb"
            }
        ]
    }

task文件的作用：定义自己需要在命令行进行的操作，组合在一起进行一个批处理。

{
        "tasks": [
            {
                "type": "shell",
                "label": "cmake",
                "command": "cmake",
                "args": [
                    "..",
                ],
               
            },
            {
                "label": "make",
                "group": {
                    "kind": "build",
                    "isDefault": true
                },
                "command":"make",
                "args": [
     
                ]
     
            },
            {
     
                "label": "Build",
                "dependsOrder": "sequence",
                "dependsOn":[
     
                    "cmake","make"
                ]
     
            }
        ],
        "version": "2.0.0",
        "options": {
         "cwd": "${workspaceFolder}/build"
        }
    }

注意设置程序为debug模式，这样才能够进行代码调试。

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall") #-o2 will optimize the code
    set(CMAKE_BUILD_TYPE Debug)

定义每次run之前要做的事情，就能够做到自动化调试了
