1. 用launch.json调试在vscode程序

• 首先在vscode安装cmake tools 和 c/c++插件，cmake 和 gsb
• 在工程里 ：新建build文件夹，然后cmake .. 和 make

记得在CMakefiles.txt加上---

调试c文件

set(CMAKE_BUILD_TYPE DEBUG)
set(CMAKE_C_FLAGS "-g")

调试c++文件

set(CMAKE_BUILD_TYPE DEBUG)
set(CMAKE_CXX_FLAGS "-g")

• 创建launch.json（用于调试）主要就是"program"位置是编译出来需要gdb的文件

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "cppdbg",
            "request": "launch",
            "name": "Debug",
            "program": "/home/pc123/Public/workspace/mqtt/mqtt-demo/MQTT-C-master/MQTT-C-master/build/simple_publisher",
            "args": [],
            "cwd": "${workspaceFolder}"
        }
    ]
}

然后直接点击调试即可，编译是cmake、make编译出来的 

2. 用sudo 权限调试程序

Hi guys,

As a workaround, you can decorate existing gdb binary with a bash script and then use it.
Steps are,

• cd /usr/bin

• sudo mv gdb gdborig

Now you need to create a bash script named gdb with following content.

• sudo vim gdb

Content of the bash is;
#!/bin/sh
sudo gdborig $@

Finally, make the script runnable.
sudo chmod 0755 gdb

Then you should be OK.
