我正在调试ubuntu18.04vm上的一个c可执行文件，我是从vs代码中ssh进入的。
这是发射台

{
    "name": "(gdb) Launch",
    "type": "cppdbg",
    "request": "launch",
    "program": "${workspaceFolder}/build/bin/exe/examples/point",
    "args": [],
    "stopAtEntry": false,
    "cwd": "${fileDirname}",
    "environment": [],
    "externalConsole": false,
    "MIMode": "gdb",
    "miDebuggerPath": "/home/vagrant/gdb",
    "setupCommands": [
        {
            "description": "Enable pretty-printing for gdb",
            "text": "-enable-pretty-printing",
            "ignoreFailures": true
        }
    ]
}

我收到此错误：

&"warning: GDB: Failed to set controlling terminal: Operation not permitted\n"
/bin/bash: /vagrant/.../point: Permission denied
/bin/bash: line 0: exec: /vagrant/.../point: cannot execute: Permission denied
[1] + Done "/home/vagrant/gdb" --interpreter=mi --tty=${DbgTerm} 0<"/tmp/Microsoft-MIEngine-In-q5crjhja.ipk" 1>"/tmp/Microsoft-MIEngine-Out-cisgbam0.mb1"

第一行并不重要，我已经被告知，但权限被拒绝的问题应该是可以修复的设置权限为777，例如。ls -lah返回-rwxrwxrwx 1 vagrant vagrant 26K Jul 14 13:54 point为指定的文件，所以权限应该没有问题，对不对？有人遇到这个问题，可以告诉我，我错过了什么？
我已经按照this的建议将gdb作为sudo运行。
