Building
Setup
Android
- Download Android NDK r10e from https://developer.android.com/ndk/downloads/older_releases.html and place it in this directory (Can't automatically download because of EULA)
- Warning: Do not attempt to build use newer or older NDK, it will lead to compilation errors.
iOS
- You should get latest Xcode (tested with Xcode 12).
