tfliteをMacOS用にビルド

tflite_flutter使っててTFLiteを自分でビルドしないといけなかったのでメモ。

CMakeをインストール

単純に指示にそう
https://cmake.org/download/

前準備

git clone https://github.com/tensorflow/tensorflow.git tensorflow_src

mkdir tflite_build
cd tflite_build
mkdir x86_64
mkdir arm64

ビルド

cd x86_64
cmake ../../tensorflow_src/tensorflow/lite/c -DCMAKE_OSX_ARCHITECTURES="x86_64"
cmake --build . -j

cd ../arm64
cmake ../../tensorflow_src/tensorflow/lite/c -DCMAKE_OSX_ARCHITECTURES="arm64"
cmake --build . -j

#cmake ../tensorflow_src/tensorflow/lite -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64"
