vscode中preLaunchTask“g++”已终止，退出代码为1的解决方案

问题背景

楼主原来做的项目,电脑中装了MinGW64。还有MinGW的32位版在用vscode时发现出现了：preLaunchTask“g++”已终止，退出代码为1的问题。找了好久。解决了问题。

launch.json

注释的位置：这里修改GDB路径为安装的mingw64的bin下的gdb.exe路径

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "preLaunchTask": "build",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "C:/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/gdb.exe", // 这里修改GDB路径为安装的mingw64的bin下的gdb.exe路径
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }]
}

tasks.json

无需任何修改

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "presentation": {
                "echo": true,
                "reveal": "always",
                "focus": false,
                "panel": "shared"
            },
            "windows": {
                "command": "g++",
                "args": [
                    "-ggdb",
                    "\"${file}\"",
                    "--std=c++11",
                    "-o",
                    "\"${fileDirname}\\${fileBasenameNoExtension}.exe\""
                ]
            }
        }
    ]
}
