Tensorflowlite with ESP32 getting compilation errors

[Sunil Bobbala]

Hi Group, 

Intro to my project. 

Working with ESP 32 (ESP-EYE). Integrating tensorflow lite to detect acoustic sounds. 

First step I cloned the git repo from (https://github.com/tensorflow/tflite-micro). 

After I do make getting the following error. 

Appreciate the help.
