Introduction:

Qt SDK is a powerful cross-platform development framework used to create applications compatible with multiple platforms, including desktop, mobile, and embedded systems. In this article, we will walk you through the step-by-step process of installing Qt SDK on your Ubuntu Linux operating system.

Step 1: Update Your System

Before installing any new software, it’s important to ensure that your system is up-to-date. Open the terminal and run the following commands:

“`

sudo apt update

sudo apt upgrade

“`

Step 2: Install Required Dependencies

Qt SDK requires some dependencies to be installed on your system. Run the following command to install those dependencies:

“`

sudo apt install build-essential libgl1-mesa-dev

“`

Step 3: Download Qt Online Installer

Visit the official Qt website (https://www.qt.io/download) and download the Qt online installer for Linux. You can also use the following command in the terminal to download the installer:

“`

wget https://download.qt.io/official_releases/online_installers/qt-unified-linux-x64-online.run

“`

Step 4: Make the Installer Executable

You need to provide execute permission for the downloaded installer file. Issue this command in the terminal:

“`

chmod +x qt-unified-linux-x64-online.run

“`

Step 5: Start Installing Qt SDK

To launch the installer, run the following command:

“`

./qt-unified-linux-x64-online.run

“`

This will open up the Qt installation wizard. Follow these steps in the installer:

1.Sign in with your Qt account or create a new one.

2.Choose a directory where you want to install Qt.

3.Select components according to your requirement, such as Qt Creator and specific Qt version.

4.Accept the license agreement and click next.

5.Once all components are downloaded, click on the Install button and wait for the installation to finish.

6.After completing the installation, press the Done button.

Step 6: Set up Environment Variables

Setting up environment variables enables the system to find the Qt binaries. Add these lines to your ~/.bashrc file:

“`

export PATH=/path/to/Qt/Tools/QtCreator/bin:$PATH

export PATH=/path/to/Qt/version/gcc_64/bin:$PATH

“`

Make sure to replace ‘/path/to/’ with the actual installation path of Qt. Save the file and close it. Afterwards, run this command in your terminal:

“`

source ~/.bashrc

“`

Now you have successfully installed Qt SDK on Ubuntu Linux.
