Hi! I have been trying to compile Tensor flow Lite Micro Arduino Port (https://github.com/tensorflow/tflite-mic...o-examples)  on STM32 with EmBitz 2.5.

Adding the folders/files  to an empty C++ project for an STM32F4 target as neeed. (TensorFlow and ThirdyParty folders and TensorFlowLite.h) .

The problem comes with the Flatbuffers lib (At  ThirdyParty  folder) that it's a bunch of .h file with C++ content.

It seems that the ide cannot assing C++ libs for this specifc library. This Tensor flow port is intended to run on CM4 targets on arduino so it should works with Embits???

Can some one help? The hw/firmware part of the for the project it's almost done I only need to build this library with Embitz and I don't want to chance for STMcube  Confused

Any one can help please?
