Building

Here you will find instructions on how to install the necessary tools for building and running the app.

Prerequisites

• The only OS supported for building Android and Linux desktop is Ubuntu 20.04. Windows build are completed using Ubuntu 20.04 on WSL2. Advanced users may also be able to build on other Debian-based distributions like Linux Mint.
• Android setup (Android Studio and subsequent dependencies)
• 100 GB of storage

Linux host

The following instructions are for building and running on a Linux host. Alternatively, see the [Windows](#Windows host) section.

Flutter

Install Flutter 3.19 beta (3.19.0-0.1.pre) by following these instructions: https://docs.flutter.dev/get-started/install/linux/desktop?tab=download#install-the-flutter-sdk. You can also clone https://github.com/flutter/flutter, check out the 3.19.0-0.1.pre tag, and add its flutter/bin folder to your PATH. Run flutter doctor in a terminal to confirm its installation.

Android Studio

Install Android Studio. Follow instructions here https://developer.android.com/studio/install#linux or install via snap:

# setup android studio
sudo apt install -y openjdk-11-jdk
sudo snap install android-studio --classic

Use Tools > SDK Manager to install:

• SDK Tools > Android SDK (API 30)
• SDK Tools > NDK
• SDK Tools > Android SDK command line tools
• SDK Tools > CMake

Then in File > Settings > Plugins, install the Flutter and Dart plugins and restart the IDE. In File > Settings > Languages & Frameworks > Flutter > Editor, enable auto format on save to match the project's code style. If you have problems with the Dart SDK, make sure to run flutter in a terminal to download it (use source ~/.bashrc to update your environment variables if you're still using the same terminal from which you ran setup.sh). Run flutter doctor to install any missing dependencies and review and agree to any license agreements.

Make a Pixel 4 (API 30) x86_64 emulator with 2GB of storage space for emulation

Install basic dependencies

sudo apt-get install libssl-dev curl unzip automake build-essential file pkg-config git python libtool libtinfo5 cmake libgit2-dev clang libncurses5-dev libncursesw5-dev zlib1g-dev llvm python3-distutils

The following may be needed for Android studio:

sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386

Install Rust with command:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.bashrc 
rustup install 1.67.1
rustup default 1.67.1

Install the additional components for Rust:

cargo install cargo-ndk --version 2.12.7

Android specific dependencies:

sudo apt-get install libc6-dev-i386
rustup target add aarch64-linux-android armv7-linux-androideabi i686-linux-android x86_64-linux-android

Linux desktop specific dependencies:

sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev liblzma-dev meson python3-pip libgirepository1.0-dev valac xsltproc docbook-xsl
pip3 install --upgrade meson==0.64.1 markdown==3.4.1 markupsafe==2.1.1 jinja2==3.1.2 pygments==2.13.0 toml==0.10.2 typogrify==2.0.7 tomli==2.0.1

After installing the prerequisites listed above, download the code and init the submodules

git clone https://github.com/cypherstack/stack_wallet.git
cd stack_wallet
git submodule update --init --recursive

Remove pre-installed system libraries for the following packages built by cryptography plugins in the crypto_plugins folder: boost iconv libjson-dev libsecret openssl sodium unbound zmq. You can use

sudo apt list --installed | grep boost

for example to find which pre-installed packages you may need to remove with sudo apt remove. Be careful, as some packages (especially boost) are linked to GNOME (GUI) packages: when in doubt, remove -dev packages first like with

sudo apt-get remove '^libboost.*-dev.*'

Run prebuild script

Certain test wallet parameter and API key template files must be created in order to run Stack Wallet. These can be created by script as in

cd scripts
./prebuild.sh
// when finished go back to the root directory
cd ..

or manually by creating the files referenced in that script with the specified content.

Build plugins

Building plugins for Android

Warning: This will take a long time, please be patient

cd scripts/android
./build_all.sh

Building plugins for Linux

cd scripts/linux
./build_all.sh

Building plugins for Windows

cd scripts/windows
./deps.sh
./build_all.sh

Running

Android

Plug in your android device or use the emulator available via Android Studio and then run the following commands:

flutter pub get
flutter run android

Note on Emulators: Only x86_64 emulators are supported, x86 emulators will not work

Linux

Run the following commands or launch via Android Studio:

flutter pub get
flutter run linux

Windows host

Visual Studio

Visual Studio is required for Windows development with the Flutter SDK. Download it at https://visualstudio.microsoft.com/downloads/ and install the "Desktop development with C++" workload, including all of its default components.

Building libraries in WSL2

Set up Ubuntu 20.04 in WSL2. Follow the entire Linux host section in the WSL2 Ubuntu 20.04 host to get set up to build. You will also need to install Rust and MXE dependencies on the WSL2 Ubuntu 20.04 host:

• Install Rust

  curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
  

• Install MXE by running stack_wallet/scripts/windows/deps.sh

  ./stack_wallet/scripts/windows/deps.sh
  

The WSL2 host may optionally be navigated to the stack_wallet repository on the Windows host in order to build the plugins in-place and skip the next section in which you copy the dlls from WSL2 to Windows. Then build windows dll libraries by running the following script on the WSL2 Ubuntu 20.04 host:

• stack_wallet/scripts/windows/build_all.sh

Copy the resulting dlls to their respective positions on the Windows host:

• stack_wallet/crypto_plugins/flutter_libepiccash/scripts/windows/build/libepic_cash_wallet.dll
• stack_wallet/crypto_plugins/flutter_liblelantus/scripts/windows/build/libmobileliblelantus.dll

Install Flutter on Windows host

Install Flutter 3.19 beta (3.19.0-0.1.pre) on your Windows host (not in WSL2) by following these instructions: https://docs.flutter.dev/get-started/install/windows/desktop?tab=download#install-the-flutter-sdk. You can also clone https://github.com/flutter/flutter, check out the 3.19.0-0.1.pre tag, and add its flutter/bin folder to your PATH. Run flutter doctor in PowerShell to confirm its installation.

Dependencies

Install the Windows SDK: https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/ You may need to install the Windows 10 SDK, which can be installed by Visual Studio (Tools > Get Tools and Features... > Modify > Individual Components > Windows 10 SDK).

Enable Developer Mode for symlink support,

start ms-settings:developers

You may need to install NuGet and CppWinRT / C++/WinRT SDKs version 2.0.210806.1:

winget install 9WZDNCRDMDM3 # NuGet, can also use Microsoft.NuGet
winget install Microsoft.Windows.CppWinRT -Version 2.0.210806.1

or download the package and manually install it by placing it in flutter/bin with nuget.exe and installing by running nuget install Microsoft.Windows.CppWinRT -Version 2.0.210806.1 in the root stack_wallet folder.

Run prebuild script

Certain test wallet parameter and API key template files must be created in order to run Stack Wallet. These can be created by script as in

cd scripts
./prebuild.ps1
// when finished go back to the root directory
cd ..

or manually by creating the files referenced in that script with the specified content.

Running

Run the following commands:

flutter pub get
flutter run -d windows
