Hi stackoverflow community,
I am trying to get a project leveraging Tensorflow Lite Micro to run on my ESP32 using PlatformIO and the Arduino framework (not ESP-IDF). Basically, I followed the guide in this medium post https://towardsdatascience.com/tensorflow-meet-the-esp32-3ac36d7f32c7 and then included everything in my already existing ESP32 project.
My project was compiling fine prior to the integration of Tensorflow Lite Micro but since integrating it, I am getting the following compile errors which seem to be related to the Tensorflow framework itself. When I uncomment everything related to Tensorflow, it compiles fine. But just when only including the following header files, it breaks:
#include "tensorflow/lite/micro/kernels/micro_ops.h"
#include "tensorflow/lite/micro/micro_error_reporter.h"
#include "tensorflow/lite/micro/micro_interpreter.h"
#include "tensorflow/lite/micro/micro_mutable_op_resolver.h"
#include "tensorflow/lite/schema/schema_generated.h"
#include "tensorflow/lite/version.h"
Does someone know where these errors come from and what I can do to solve those?
Here is the error trace:

I resolved this for now by switching from the Arduino framework to the ESP-IDF framework. With this, it works like a charm.
