usage

1. use binary executable

download

2. compile

2.1. pre-installed

• rustup install
• rust (nightly version)
• flutter (master channel)

2.2. compile rust code to dynamic link library (ffi)

2.2.1. auto-compile script

it is recommended to use rust.sh to auto-compile the rust code

2.2.2. manually compile

linux / macos / windows

• cargo build --release

linux

• cp target/release/libesse.a core/linux/share/libesse.a

macos

• cp target/release/libesse.a core/macos/share/libesse.a

windows

• cp target/release/esse.dll core/windows/share/esse.dll
• cp target/release/esse.dll.lib core/windows/share/esse.dll.lib

android

1. add your android device target

• rustup target add aarch64-linux-android
• rustup target add armv7-linux-androideabi
• rustup target add x86_64-linux-android

2. configure your ndk
3. build the jnilibs

• cargo build --release --target=aarch64-linux-android
• cp target/aarch64-linux-android/release/libesse.so core/android/src/main/jnilibs/arm64-v8a/

ios

1. install lipo
2. cargo lipo --release
3. cp target/universal/release/libesse.a core/ios/share/libesse.a

2.3. run flutter to build binary

• run flutter run or flutter run --release in terminal, or
• for android, run flutter build apk, or
• for linux, run flutter build linux, or
• for macos, run flutter build macos, or
• for windows, run flutter build windows
