Setting Up a macOS Development Environment for Rust

This guide will help you install Rust and set up a Substrate development environment on Apple macOS computers with either Intel or Apple M1 processors.

Before You Begin

Ensure your computer meets the following requirements:

• Operating System: macOS 10.7 Lion or later

• Processor: At least 2GHz (3GHz recommended)

• Memory: At least 8 GB RAM (16 GB recommended)

• Storage: At least 10 GB available space

• Internet: Broadband connection

Step 1: Install Homebrew

If you don't have Homebrew installed, you should install it to manage packages on macOS.

1. Open the Terminal application.

2. Download and install Homebrew by running:

   Copy

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

3. Verify Homebrew installation:

   Copy

   brew --version

Step 2: Install Required Packages

1. Update Homebrew:

   Copy

   brew update

2. Install required packages:

   Copy

   brew install protobuf openssl cmake python git

Step 3: Install Rust

1. Download and run the rustup installation script:

   Copy

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

2. Follow the prompts for default installation.

3. Update your current shell to include Cargo:

   Copy

   source ~/.cargo/env

4. Verify Rust installation:

   Copy

   rustc --version

5. Configure Rust to use the stable version and update:

   Copy

   rustup default stable
   rustup update
   rustup target add wasm32-unknown-unknown

6. Add the nightly toolchain and WebAssembly (wasm) targets:

   Copy

   rustup update nightly
   rustup target add wasm32-unknown-unknown --toolchain nightly

7. Verify the configuration:

   Copy

   rustup show
   rustup +nightly show

Compile a Substrate Node

Now that Rust is installed and configured, you can compile a Substrate node.

Step 1: Clone the Node Template Repository

1. Clone the Substrate node template repository:

   Copy

   git clone https://github.com/devolved-ai/argochain
   cd argochain

Step 2: Compile the Node Template

1. Compile the node template:

   Copy

   cargo build --release

   The compilation process may take several minutes.

Your development environment is now set up for Substrate development.
