Learning Objectives

• How to install Rust.
• Create and execute a Rust file

• Ubuntu Linux OS version 18.04
• Rust version 1.47.0
• Visual Studio Code version 1.45.0 (code editor)

However you may use any other editor of your choice.

• You need an internet connection to install the necessary packages and
• You should be familiar with basic Linux commands.
• If not, please go through the prerequisite Linux tutorials on this website.

• The files used in this tutorial are available in the Code files link on this tutorial page.
• Pls download and extract the files.
• Make a copy and then use them for practising.

And I will use the same file to copy-paste the commands during the demonstration.

Shortcut to paste commands on the terminal is Shift, Ctrl and V keys.

Ensure that you have root permissions to run the commands.

Type:

sudo apt-get install curl -y

[Enter]

So, we have to first install curl if we haven’t done so earlier.

To do so type the command as shown on the terminal.

Enter admin password

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

[Enter]

Next let us download and install Rust using Curl.

To do so type the command as shown on the terminal.

Proceed with installation (default)

Customize installation

Cancel installation

Proceed with installation (default)

Customize installation

Cancel installation

Rust is installed now. Great!

sudo reboot [Enter]

To do so, type sudo reboot in the terminal.

This will restart your computer.

rustc --version [Enter]

Type the command as shown in the terminal.

rustc 1.47.0

The version number may be different in your case.

rustup [Enter]

rustup is responsible for the complete Rust installation using the curl command.

rustup update [Enter]

For now, I have only one stable version installed.

If you have any other versions, then that version would be displayed.

cargo [Enter]

This shows a list of commands which can be executed using cargo.

cargo --version [Enter]

• System restart is required after installing rust.
• If not, we could land with these errors
  • Rustup
  • Rustc
  • Cargo - command not found

I will use Visual Studio Code editor for this demonstration.

fn main() {

println!("Hello World");

}

fn main(){

}

The Rust execution starts from the main function.

{

}

Hello World

print!(“Hello World”)

Now, it’s time to compile and run the file.

cd Desktop/MyRustProject

[Enter]

In my case, it is MyRustProject on the Desktop.

rustc hello-world.rs [Enter]

In my case it is hello-world.rs

./hello-world [Enter]

Now, to run type the dot slash filename and press Enter.

In my case it is ./hello-world

Hello World

sudo apt install build-essential

• You could land up with this error while compiling - linker ‘cc’ not found.
• It means you don’t have gcc in your machine.
• To resolve this, install the build essentials with this command.

With this we have come to the end of this tutorial.
