ubuntu下vscode配置问题

大家知道这是什么问题吗，为什么运行launch.json就会出现这两个提示（build终止运行，退出代码为-1，launch.out找不到），网上找了很久，什么改成com……也不对

launc.json代码

{

"version": "0.2.0",
"configurations": [
{
    "name": "(gdb) Launch",
    "type": "cppdbg",
    "request": "launch",
    "program": "${workspaceFolder}/${fileBasenameNoExtension}.out",
    "args": [],
    "stopAtEntry": false,
    "cwd": "${workspaceFolder}",
    "environment": [],
    "externalConsole": true,
    "MIMode": "gdb",
    "preLaunchTask": "build",
    "setupCommands": [
        {
        "description": "Enable pretty-printing for gdb",
        "text": "-enable-pretty-printing",
        "ignoreFailures": true
        }
    ]
}
]
