Code dependency and environment preparation

• rustc 1.77.2 (25ef9e3d8 2024-04-09) or above

  For china mainland developer: You can use rsproxy.cn to speed up the compilation

• iOS development environment preparation: (Only for M1/M2 machine)

    rustup target add aarch64-apple-ios aarch64-apple-ios-sim x86_64-apple-darwin

• Android development environment preparation:
  • Download ndk, ndk download
    • wget "https://dl.google.com/android/repository/android-ndk-r25c-linux.zip"
    • unzip the ndk file, modify .profile file, add environment variable:

      export NDK_HOME=/home/YOUR/ndk/android-ndk-r25c

  • Add android toolchain to cargo

    cargo install cargo-ndk
    rustup target add aarch64-linux-android x86_64-linux-android

How to build

iOS build

• Debug version: simulator

    cargo build --target aarch64-apple-ios-sim
    # if you are using x86 machine
    cargo build  --target x86_64-apple-darwin 

    # build swift binding code
    cargo run --target aarch64-apple-ios-sim --bin bindgen -- --language swift

• Release version: device
