NOTE: for now compiling on windows is not supported b/c of poor support of Rust cross-compiling wrt to Android NDK
It can probably be fixed but setting up Windows as dev env is a pain; it requires at least: Perl, Python, Rust, C++ Dev Tools, etc
Uses:
- Kotlin multiplatform to share as much code as possible b/w Android and iOs
- Android: Jetpack Compose for easy UI
- [TODO] iOs: SwiftUI for easy UI
NOTE: the Rust dependencies only compile on nightly
TODO cleanup/rewrite below
- install Python
- install Perl?
-[windows] FAIL: "This perl implementation doesn't produce Unix like paths"
Probably b/c https://github.com/alexcrichton/openssl-src-rs/blob/main/src/lib.rs#L226 hardcoded all Android NDK to match Linux...

rustup toolchain install nightlyrustup target add aarch64-apple-ios x86_64-apple-ios --toolchain nightly- Install Android Studio
- Android Studio: open the project "wallet-app"; this is needed to download the SDK etc else iOs can not compile
- NOTE: you will have to download eg the NDK using the SDK Manager, and anything else that is required until you can Build on this machine
- Once you have built the Android App successfully once, you can close Android Studio
- Open the folder iOsApp in XCode and dev/compile/whatever
- MAYBE Download a simulator using XCode?
- else:
cargo:warning=xcrun: error: SDK "iphonesimulator" cannot be locatedcargo:warning=xcrun: error: unable to lookup item 'Path' in SDK 'iphonesimulator'
- else:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer/- [to build on command line]
.../wallet-app/iosApp$ xcodebuild -scheme iosApp -sdk iphonesimulator build- [for real device]
xcodebuild -scheme iosApp build CODE_SIGN_IDENTITY=''NOTE: gradle task "embedAndSignAppleFrameworkForXcode" will fail if signing not setup; but at least that allows testing Rust arm64 cross-compiling
- [for real device]
NOTE: below SHOULD already be set, but double check the value:
- Project settings -> click "+" add "new User defined":
JAVA_HOME- eg
/Applications/Android Studio.app/Contents/jre/Contents/Home/(no need for double quotes or escaping) - ALTERNATIVE: add
export JAVA_HOME=/Applications/Android\ Studio.app/Contents/jre/Contents/Homebefore ./gradlew inBuild Phase -> Run Script-> works but ugly
- eg
Process: gg.interstellar.wallet.android, PID: 26011 java.lang.UnsatisfiedLinkError: dlopen failed: library "libshared_substrate_client.so" not found
- CHECK eg
ll shared/rust/target/BUILD_VARIANT/debug/ - make sure the selected Build Variant is the correct one
cf rust-lang/rust#85806 (comment)
TODO check rust-mobile/ndk#270 and rust-lang/rust#85806 for alternative
$ cat /etc/wsl.conf
[boot]
command = /bin/bash -c 'chown root:kvm /dev/kvm && chmod 660 /dev/kvm'sudo usermod -a -G kvm <username>
- install NDK using Android Studio "SDK Manager"(ie "NDK (Side by side)" latest)
- FOR NOW MUST BE <r23, cf below
- rust-lang/rust#85806 and rust-mobile/ndk#189
- NO:
cargo install cargo-ndk- MAYBE
cargo install ndk-buildinstead: NO, it is a lib, and can only work as part of https://github.com/rust-windowing/android-ndk-rs/tree/master/cargo-apk ?
- MAYBE
rustup target add aarch64-linux-android armv7-linux-androideabi- maybe later add
x86_64-linux-android i686-linux-androidbut that cover maybe 1% of devices?
- maybe later add
- CHECK
cargo ndk -t armeabi-v7a -t arm64-v8a -o ./jniLibs buildNOTE: is will be called by gradle when needed, but better check in advance--release
NO! install Python! cf https://github.com/mozilla/rust-android-gradle/blob/master/plugin/src/main/resources/com/nishtahir/linker-wrapper.bat
NOTE: this is needed if you want to compile the Rust project directly instead of using Gradle
