libp2p iOS

Attempt to get libp2p-rs working on iOS.

Getting Started

This project is in "hacking" mode at the moment. The goal is to get libp2p-rs to compile for iOS so can be used in an iOS application.

Prerequisites

What things you need to install the software and how to install them

TODO

Installing

Setup

  1. Install the common build tools like C compiler and linker. On macOS, get Xcode, and install the command line tools.

    xcode-select --install

  2. Download rustup. We will use this to setup Rust for cross-compiling.

    curl https://sh.rustup.rs -sSf | sh

  3. Download targets for iOS

    # iOS. Note: you need *all* five targets
rustup target add aarch64-apple-ios armv7-apple-ios armv7s-apple-ios x86_64-apple-ios i386-apple-ios

  4. Install cargo-lipo to generate the iOS universal library.

    cargo install cargo-lipo

Creating the library

  1. Build the library.

    # iOS
cargo lipo --release

  2. Build the Xcode project. - TODO

    cd examples/ios
xcodebuild -configuration Release -scheme RustChat | xcpretty
cd ../..

    When you create an Xcode project yourself, note the following points:

    • Add the C header rust_chat.h to allow using the Rust functions from C.
    • Copy target/universal/release/lib???.a to the project. You may need to modify LIBRARY_SEARCH_PATHS to include the folder of the *.a file.
    • Note that cargo-lipo does not generate bitcode yet. You must set ENABLE_BITCODE to NO. (See also http://stackoverflow.com/a/38488617)
    • You need to link to libresolv.tbd.
