前言

vscode 可以快速配置 cmake 编译c++工程项目，完成日常工程开发。

---

一、tasks.json 配置

以下是 tasks.json 配置：

{
	"version": "2.0.0",
	"options": {
		"cwd": "${workspaceFolder}/build/" // 统一配置 tasks 命令执行的目录
	},
	"tasks": [
		{
			"label": "cmake",
			"type": "shell",
			"command": "cmake", // 测试了 `cmake ../build && make ` 一行命令不生效，会编译报错
			"args": [
				"-DCMAKE_BUILD_TYPE=Debug",
				"-DCMAKE_EXPORT_COMPILE_COMMANDS=1", // 生成compile_commands.json文件
                ".."
			],
		},
		{
			"label": "make",
			"type": "shell",
			"command": "make",
			"args": [],
			"group": {
                "kind": "build",
                "isDefault": true
            },
            "dependsOn":["cmake"] // 执行make之前，需先执行cmake
		}
	]
}

二、launch.json 配置

以下是 launch.json 配置：

{
    // 使用 IntelliSense 了解相关属性。 
    // 悬停以查看现有属性的描述。
    // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [

    {
      "name": "gdb myprocess install",
      "type": "cppdbg",
      "request": "launch",
      "program": "${workspaceFolder}/build/myprocess", // myprocess 为可执行文件
      "args": [
        "install",
        "org.gnome.Dictionary",
      ],
      "stopAtEntry": false,
      "cwd": "${workspaceFolder}/build",
      "environment": [],
      "externalConsole": false,
      "MIMode": "gdb",
      "miDebuggerPath": "/usr/bin/gdb",
      "setupCommands": [
        {
          "description": "Enable pretty-printing for gdb",
          "text": "-enable-pretty-printing",
          "ignoreFailures": true
        }
      ],
      "preLaunchTask": "cmake"
    }
    ]
}

总结

vscode 首先需要安装 cmake 和 cmake tools 插件，然后配置相关 launch.json 和 tasks.json 文件，之后就可以通过 F5 快捷键运行了。
