The following commands were run on macOS Monterey - version 12.1 Terminal on VS Code

git clone https://github.com/mocleiri/tensorflow-micropython-examples.git

Then Following the build_esp32s3.yml in the .github/workflows folder.

cd /tensorflow-micropython-examples

git submodule init
git submodule update --recursive
cd micropython
git submodule update --init lib/axtls
git submodule update --init lib/berkeley-db-1.xx
cd ..

IDF_COMMIT=142bb32c50fa9875b8b69fa539a2d59559460d72
echo "esp-idf-commit=$IDF_COMMIT" >> $GITHUB_ENV
TFLM_COMMIT=$(git submodule status tensorflow | awk '{print ($1)}')
echo "tflm-commit=$TFLM_COMMIT" >> $GITHUB_ENV

source ./micropython/tools/ci.sh && ci_esp32_idf44_setup

source ./esp-idf/export.sh

pip3 install Pillow
pip3 install Wave

echo "Regenerating microlite/tfm directory"
rm -rf ./micropython-modules/microlite/tflm

cd ./tensorflow

../micropython-modules/microlite/prepare-tflm-esp.sh

cd ..

source ./esp-idf/export.sh

cd ./micropython

echo "make -C mpy-cross V=1 clean all"

make -C mpy-cross V=1 clean all

cd ..

echo "cd ./boards/esp32/MICROLITE_S3"
cd ./boards/esp32/MICROLITE_S3

echo "Building MICROLITE_S3"
rm -rf build
idf.py clean build

I can find all of these files by hand in the downloaded ESP-IDF in the repository but the compiler just can't seem to pick them up. any suggestions would be fantastic thank you!

Copying and pasting the missing individual folder and files into the board root folder does seem to partially solve it but then produces further errors:

etc for all of the remaining build lines

My development environment is windows but I'm doing most work in visual studio code running in windows subsystem for linux so I'm unable to help directly.

However if you are able to figure out the steps to build on MacOS please feel free to contribute the steps and we can improve the manual build instructions to include for mac os.

The -fno-rtti error is not an error per-se. I need to improve the microlite cmake file to seperate the C++ build from the C build.
CMake is passing that option to gcc which is complaining that its not a C option. But I added for the C++ code where it is needed.

That line is emitted right now for all esp32 builds in linux.

If you get a firmware generated at the end of the build then I think you have a working build.

Thank you for your reply! I will focus on the mac build and reply back to the thread so it can be added. Thanks again!

Solved: Ive solved it using latest IDF-4.4 and making sure all of the toolchain had been properly added to the bash Profile. Ive added a pull request with a .md document detailing the process.

The Process is as pasted below:

Build Tensorflow Micropython on MAC OS using Bash Terminal

Tested on: macOS Monterey Version 12.1

Prerequisites

Properly Installing ESP-IDF (Taken from: https://docs.espressif.com/projects/esp-idf/en/v3.3/get-started-cmake/macos-setup.html)

sudo easy_install pip

pip install --user pyserial

brew install cmake ninja

brew install ccache

Download: https://dl.espressif.com/dl/xtensa-esp32-elf-osx-1.22.0-80-g6c4433a-5.2.0.tar.gz

mkdir -p ~/esp
cd ~/esp
tar -xzf ~/Downloads/xtensa-esp32-elf-osx-1.22.0-80-g6c4433a-5.2.0.tar.gz

Make Toolchain Accessible from Bash Terminal

Open your /bash.profile file by navigating to usr directory and pressing down the keys "Command, Shift, FullStop" it shoudl appear.

Add to your profile:

export PATH=$HOME/esp/xtensa-esp32-elf/bin:$PATH
alias get_esp32="export PATH=$HOME/esp/xtensa-esp32-elf/bin:$PATH"

Git Clone ESP-IDF Version 4.4

cd ~/esp
git clone -b v4.4 --recursive https://github.com/espressif/esp-idf.git esp-idf

Update the Submodules

cd esp-idf
git submodule update --init

Reopen your /bash.profile and add the following:

export IDF_PATH=~/esp/esp-idf
export PATH="$IDF_PATH/tools:$PATH"

Install the required python packages

python3 -m pip install --user -r $IDF_PATH/requirements.txt
