Before you begin

Check the documentation for your operating system for information about the packages that are installed and how to download and install any additional packages you might need. For example, if you use Ubuntu, you can use the Ubuntu Advanced Packaging Tool (apt) to install the build-essential package:

sudo apt install build-essential

At a minimum, you need the following packages before you install Rust:

clang curl git make

Because the blockchain requires standard cryptography to support the generation of public/private key pairs and the validation of transaction signatures, you must also have a package that provides cryptography, such as libssl-dev or openssl-devel.

Install required packages and Rust

To install the Rust toolchain on Linux:

1. Log on to your computer and open a terminal shell.

2. Check the packages you have installed on the local computer by running an appropriate package management command for your Linux distribution.

3. Add any package dependencies you are missing to your local development environment by running an appropriate package management command for your Linux distribution.

   For example, on Ubuntu Desktop or Ubuntu Server, you might run a command similar to the following:

   sudo apt install --assume-yes git clang curl libssl-dev protobuf-compiler

   Click the tab titles to see examples for other Linux operating systems:

   DebianArchFedoraOpensuse

   sudo apt install --assume-yes git clang curl libssl-dev llvm libudev-dev make protobuf-compiler

   Remember that different distributions might use different package managers and bundle packages in different ways. For example, depending on your installation selections, Ubuntu Desktop and Ubuntu Server might have different packages and different requirements. However, the packages listed in the command-line examples are applicable for many common Linux distributions, including Debian, Linux Mint, MX Linux, and Elementary OS.

4. Download the rustup installation program and use it to install Rust by running the following command:

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

5. Follow the prompts displayed to proceed with a default installation.

6. Update your current shell to include Cargo by running the following command:

   source $HOME/.cargo/env

7. Verify your installation by running the following command:

   rustc --version

8. Configure the Rust toolchain to default to the latest stable version by running the following commands:

   rustup default stable
   rustup update

9. Add the nightly release and the nightly WebAssembly (wasm) targets to your development environment by running the following commands:

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

10. Verify the configuration of your development environment by running the following command:

    rustup show
    rustup +nightly show

    The command displays output similar to the following:

    # rustup show
    
    active toolchain
    ----------------
    
    stable-x86_64-unknown-linux-gnu (default)
    rustc 1.62.1 (e092d0b6b 2022-07-16)
    
    # rustup +nightly show
    
    active toolchain
    ----------------
    
    nightly-x86_64-unknown-linux-gnu (overridden by +toolchain on the command line)
    rustc 1.65.0-nightly (34a6cae28 2022-08-09)
