Jiakai Liu c3f881cdbc add script to build mobile library with host toolchain (#26440) 
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/26440

As we are optimizing build size for Android/iOS, it starts diverging
from default build on several build options, e.g.:
- USE_STATIC_DISPATCH=ON;
- disable autograd;
- disable protobuf;
- no caffe2 ops;
- no torch/csrc/api;
...

Create this build_mobile.sh script to 'simulate' mobile build mode
with host toolchain so that people who don't work on mobile regularly
can debug Android/iOS CI error more easily. It might also be used to
build libtorch on devices like raspberry pi natively.

Test Plan:
- run scripts/build_mobile.sh -DBUILD_BINARY=ON
- run build_mobile/bin/speed_benchmark_torch on host machine

README.md

This directory contains the useful tools.

build_android.sh

This script is to build PyTorch/Caffe2 library for Android. Take the following steps to start the build:

  • set ANDROID_NDK to the location of ndk
export ANDROID_NDK=YOUR_NDK_PATH
  • run build_android.sh
#in your PyTorch root directory
bash scripts/build_android.sh

If succeeded, the libraries and headers would be generated to build_android/install directory. You can then copy these files from build_android/install to your Android project for further usage.

You can also override the cmake flags via command line, e.g., following command will also compile the executable binary files:

bash scripts/build_android.sh -DBUILD_BINARY=ON

build_ios.sh

This script is to build PyTorch/Caffe2 library for iOS, and can only be performed on macOS. Take the following steps to start the build:

  • Install Xcode from App Store, and configure "Command Line Tools" properly on Xcode.
  • Install the dependencies:
brew install cmake automake libtool
  • run build_ios.sh
#in your PyTorch root directory
bash scripts/build_ios.sh

If succeeded, the libraries and headers would be generated to build_ios/install directory. You can then copy these files to your Xcode project for further usage.
