1. 工程根目录创建一个名为gdb的可执行脚本。

vim gdb，脚本内容如下，sudo chmod 777 gdb 使脚本可执行。

sudo /usr/bin/gdb "$@"

2. .vscode文件夹下的launch.json增加或改动

"miDebuggerPath": "${workspaceRoot}/gdb"

3. 更改/etc/sudoers，增加一行，user_name为自己账号名。

user_name ALL=(ALL) NOPASSWD:/usr/bin/gdb

4. /etc/sudoers为只读文件，更改了需要把文件权限改回去。

pkexec chmod 0440 /etc/sudoers
