Following Development

Work is merged into base on a bi-weekly (once every two weeks) schedule.

Development can be followed in multiple ways:

1. Issues are put into the project overview
   • This is a good way to see what work is assigned and the various views into how goals are being met
2. What’s Cooking on Anoma
3. Research Forums
   • This is good for seeing discussions on the direction of Anoma
   • The architecture posts in particular are a practical vision for how the codebase’s architecture will evolve. Around two of these get posted per week
4. Issues and pull requests
   • This is good for viewing new issues and work coming in, but the other views are typically a better way to view this

Running pre-built binaries

Release Dependencies

To run a working Anoma Node the following dependencies are required:

1. Mac OS X Development Environment:
   • Install Apple Command Line Developer Tools: xcode-select --install
   • Install MacPorts (or equivalent package manager)
2. Install ncurses (Mac OS X only)
3. Install OpenSSL:
   • Mac OS X and Linux: use package manager
   • Windows: not required

     Running

     Download the Anoma release for your platform, extract it, and run bin/anoma.

     Compilation from sources

     Build Dependencies

Dependencies needed regardless of platform.

• Elixir: consult the installation instructions here

• Rust: consult the installation instructions here.

• Protobuf: consult the installation instructions here

• Elixir plugin for protobufs protoc-gen-elixir

  mix escript.install hex protobuf 0.11.0

  Note here that the version is important. After installing this plugin, ensure that it is available in your path. If you are using asdf, call asdf reshim. If not, add export PATH=~/.mix/escripts:$PATH to your .bashrc or .zshrc.

  Verify all is well.

  $ protoc-gen-elixir --version
  0.11.0

---

MacOS

Ensure Apple Command Line Developer Tools are installed.

xcode-select --install

Using brew, install the following dependencies.

brew install elixir cmake protobuf git

---

Ubuntu/Debian

Dependencies that you might not have installed.

apt install cmake libwxgtk3.2-dev

---

Windows

• Install Build Tools for Visual Studio 2022 (Workload: Visual C++ build tools)
• Install PowerShell

---

Compiling and Running

To install the dependencies as well as Anoma run:

mix deps.get
mix compile

To start an Anoma instance run one of these:

iex -S mix # starts an interactive shell
mix run --no-halt # starts a non-interactive shell

See the Contributing section for how to get the best use of the interactive shell.

Further see the Known issues section if you encounter an issue.

Docker images

To work with Docker images, do the following:

1. Install Docker, this is necessary for both building and running Docker images
2. Build the Anoma image from the repository root: docker build -t <IMAGE> .
   • <IMAGE> is your chosen image name
3. Run the Anoma image: docker run -it --network host <IMAGE> <SUBCOMMAND>
   • <IMAGE> is the name of Anoma Docker image to be run
   • <SUBCOMMAND>is interpreted by the Anoma binary
   • --network host will enable connections from the host

Contributing

Please read the contributor’s guide for in depth details about the codebase.

Known Issues

(Mix) Could not compile dependency :enacl

For some versions of OSX (and Linux), our enacl package may have compilation issues.

To get around it please run

git checkout mariari/no-libsodium
mix clean
mix deps.get
mix compile

could not compile dependency :cairo, “mix compile”

The rust compiler can be quite picky about our cairo dependencies. This is likely caused by an incompatible rust-toolchain.

To get around it you may have to run a command like:

rustup toolchain add 1.76.0
# for OSX you may try 1.76.0-aarch64-apple-darwin

Once this is had, the Cairo issues should go away.

Git

This codebase follows a git style similar to git or linux.

New code should be based on base, and no attempt to keep it up to sync with main should be had. When one’s topic is ready, just submit a PR on github and a maintainer will handle any merge conflicts.

There are bi-weekly releases, so do not be afraid if a maintainer says the PR is merged but it’s still open, this just means that it’s merged into next or main and will be included in the next scheduled release.

Happy hacking, and don’t be afraid to submit patches.
