# Raspberry Pi 4 Installation
|
|
|
|
|
|
|
|
|
|
Tested on:
|
|
|
|
|
|
|
|
|
|
- Raspberry Pi 4 Model B (4GB)
|
|
|
|
|
- `Ubuntu 20.04 LTS (GNU/Linux 5.4.0-1011-raspi aarch64)`

|
|
|
|
|
*Note: [Lighthouse supports cross-compiling](./cross-compiling.md) to target a
|
|
|
|
|
Raspberry Pi (`aarch64`). Compiling on a faster machine (i.e., `x86_64`
|
|
|
|
|
desktop) may be convenient.*

|
|
### 1. Install Ubuntu
|
|
|
|
|
|
|
|
|
|
Follow the [Ubuntu Raspberry Pi installation instructions](https://ubuntu.com/download/raspberry-pi).
|
|
|
|
|
|
|
|
|
|
**A 64-bit version is required** and latest version is recommended (Ubuntu
|
|
|
|
|
20.04 LTS was the latest at the time of writing).
|
|
|
|
|
|
|
|
|
|
A graphical environment is not required in order to use Lighthouse. Only the
|
|
|
|
|
terminal and an Internet connection are necessary.
|
|
|
|
|
|
|
|
|
|
### 2. Install Packages
|
|
|
|
|
|
|
|
|
|
Install the [Ubuntu Dependencies](installation.md#dependencies-ubuntu).
|
|
|
|
|
(I.e., run the `sudo apt install ...` command at that link).
|
|
|
|
|
|
|
|
|
|
> Tips:
|
|
|
|
|
>
|
|
|
|
|
> - If there are difficulties, try updating the package manager with `sudo apt
|
|
|
|
|
> update`.
|
|
|
|
|
|
|
|
|
|
### 3. Install Rust
|
|
|
|
|
|
|
|
|
|
Install Rust as per [rustup](https://rustup.rs/). (I.e., run the `curl ... `
|
|
|
|
|
command).
|
|
|
|
|
|
|
|
|
|
> Tips:
|
|
|
|
|
>
|
|
|
|
|
> - When prompted, enter `1` for the default installation.
|
|
|
|
|
> - Try running `cargo version` after Rust installation completes. If it cannot
|
|
|
|
|
> be found, run `source $HOME/.cargo/env`.
|
|
|
|
|
> - It's generally advised to append `source $HOME/.cargo/env` to `~/.bashrc`.
|
|
|
|
|
|
|
|
|
|
### 4. Install Lighthouse
|
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
git clone https://github.com/sigp/lighthouse.git
|
|
|
|
|
cd lighthouse
|
|
|
|
|
make
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Compiling Lighthouse can take up to an hour. The safety guarantees provided by
|
|
|
|
|
the Rust language unfortunately result in a lengthy compilation time on a
|
|
|
|
|
low-spec CPU like a Raspberry Pi.
|
|
|
|
|
|
|
|
|
|
Once installation has finished, confirm Lighthouse is installed by viewing the
|
|
|
|
|
usage instructions with `lighthouse --help`.
