In this guide, we will delve into the steps required to install LeoCAD on Linux Mint 20.1, a popular linux distribution celebrated for its user-friendly interface and robust performance.

System Requirements

Before diving into the installation process, it’s crucial to ensure your system meets the necessary requirements:

• Operating System: Linux Mint 20.1 or later (based on Ubuntu 20.04)
• RAM: At least 2 GB (4 GB or more recommended for complex models)
• Storage: A minimum of 200 MB of disk space for installation
• Graphics: OpenGL 2.0 compatible graphics card

Verifying these criteria will help ensure a smooth installation and optimal functioning of LeoCAD on your device.

Installing LeoCAD on Linux Mint 20.1

Step 1: Updating Your System

Before installing any new software, it’s prudent to update your package manager to ensure all system components are current.

1. Open your terminal by pressing Ctrl + Alt + T.

2. Type the following command to update your package list:

   bash
   sudo apt update

3. Next, upgrade the existing packages with:

   bash
   sudo apt upgrade

This process may take some time, depending on how many updates need to be installed.

Step 2: Installing Dependencies

LeoCAD relies on specific libraries and tools to function correctly. Installing these dependencies beforehand can prevent issues during the installation stage. Run the following command:

bash
sudo apt install build-essential qt5-default qttools5-dev-tools libqt5svg5-dev libglew-dev libglm-dev

In this command:

• build-essential installs tools needed for building packages.
• qt5-default provides the necessary Qt framework for GUI applications.
• The other libraries are for graphics rendering and UI capabilities required by LeoCAD.

Step 3: Downloading LeoCAD

After preparing your system, the next step is to download the latest version of LeoCAD:

1. Go to the LeoCAD official website.
2. Navigate to the “Download” section.
3. Select the version suitable for Linux, typically available as a .tar.gz archive.

Alternatively, use the terminal to download directly:

bash
wget https://github.com/LeoCAD/leocad/releases/download/latest/leocad-linux-x86_64.tar.gz

Step 4: Extracting the Files

Once the download is complete, you need to extract the contents of the .tar.gz file:

bash
tar -xzvf leocad-linux-x86_64.tar.gz

This command will create a directory containing LeoCAD’s files.

Step 5: Running LeoCAD

You can now run LeoCAD directly from the terminal. Navigate to the directory created during extraction:

bash
cd leocad-linux-x86_64

Finally, execute LeoCAD with the following command:

bash
./leocad

If the installation process has gone smoothly, LeoCAD should now launch, allowing you to begin creating your LEGO masterpieces!
