【环境配置】使用vscode g++编译c/c++程序

注

由于vscode环境被搞炸了一次，又不想重装，就重新配了一下launch和task，主要是为了断步调试，只是编译的话用cmake和Makefile都可以

其次，runcode扩展似乎与gcc/g++有冲突，建议先禁用

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) 启动",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/tt.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "D:/MinGW64/bin/gdb.exe",
            "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": "C/C++: g++.exe"
        }

    ]
}

task.json

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "cppbuild",
			"label": "C/C++: g++.exe",
			"command": "D:/MinGW64/bin/g++.exe",
			"args": [
				"-fdiagnostics-color=always",
				"-g",
				"${file}",
				"-o",
				"${fileDirname}\\${fileBasenameNoExtension}.exe"
			],
			"options": {
				"cwd": "D:/MinGW64/bin"
			},
			"problemMatcher": [
				"$gcc"
			],
			"group": {
				"kind": "build",
				"isDefault": true
			},
			"detail": "编译器: D:/MinGW64/bin/g++.exe"
		}
	]
}

具体要点说明

1. 通常我们创建task时，里面是空的，需要在右下角添加配置
2. launch里，"preLaunchTask"的属性值 要和 task里，"label"的属性值相等
3. launch里，"miDebuggerPath"需要自己填，找到目标编译器地址就行
4. launch里，"program"中查找的.exe名称要和task里“args -o”下生成的.exe名称相同，且在同一目录下

   我这里不一样是因为我的cpp文件名称就是tt，因此 ${fileBasenameNoExtension} == tt

5. “args -g”下，是需要参与编译的文件，通常保持${file}即可，如果文件结构比较奇特，或者不希望有些文件参与编译，则需要手动填写
