Prerequisites

Before diving into the installation process, it’s crucial to ensure your system meets the necessary requirements and has the essential tools in place. Here’s what you’ll need:

A computer running Ubuntu 24.04 LTS (Jammy Jellyfish)
An active internet connection for downloading packages
Terminal access (press Ctrl + Alt + T to open)
Sudo privileges on your user account

It’s worth noting that while qView is designed to be lightweight, ensuring your system has at least 2GB of RAM and 10GB of free disk space will guarantee optimal performance. Additionally, having a non-root sudo user is crucial for maintaining system security during the installation process.

Step 1: Update Your System

Before installing any new software, it’s always a good practice to update your system. This ensures that you have the latest security patches and package information, reducing the likelihood of conflicts during the installation process.

Open your terminal and run the following commands:

sudo apt update
sudo apt upgrade -y

The first command updates the package list, while the second upgrades all installed packages to their latest versions. The “-y” flag automatically answers “yes” to any prompts, streamlining the upgrade process.

Step 2: Install Dependencies

qView relies on several dependencies to function correctly. These are libraries and tools that the application needs to run smoothly on your Ubuntu system. Let’s install these dependencies:

sudo apt install build-essential qt5-qmake qtbase5-dev libqt5svg5-dev

Here’s a breakdown of what each package does:

build-essential: This meta-package includes essential tools for compiling software, such as GCC and Make.
qt5-qmake: The Qt build system, necessary for compiling Qt applications like qView.
qtbase5-dev: Development files for Qt 5 core libraries.
libqt5svg5-dev: Development files for Qt 5 SVG module, which qView uses for rendering certain image types.

Installing these dependencies ensures that qView will have all the necessary components to run efficiently on your Ubuntu 24.04 LTS system.

Step 3: Installing qView via PPA

The most straightforward method to install qView on Ubuntu 24.04 LTS is through a Personal Package Archive (PPA). A PPA is a repository hosted on Launchpad that allows developers to distribute software easily.

Follow these steps to add the qView PPA and install the application:

Add the qView PPA to your system:

sudo add-apt-repository ppa:jurplel/qview

Update your package list to include the new PPA:
```
sudo apt update
```
Install qView using APT:
```
sudo apt install qview
```

This method ensures you receive automatic updates for qView whenever they’re available through the Ubuntu update system.

Step 4: Building from Source (Optional)

While installing via PPA is recommended for most users, some may prefer to build qView from source. This approach offers more control over the installation process and allows you to use the latest development version.

To build qView from source, follow these steps:

Install Git if you haven’t already:
```
sudo apt install git
```

Clone the qView repository:

git clone https://github.com/jurplel/qView.git

Navigate to the qView directory:
```
cd qView
```
Create a build directory and navigate into it:
```
mkdir build && cd build
```
Generate the Makefile:
```
qmake ../qView.pro
```
Compile the application:
```
make
```
Install qView system-wide:
```
sudo make install
```

Building from source can be more time-consuming and may require additional troubleshooting. However, it provides the latest features and allows for customization during the build process.

Troubleshooting the Build Process

If you encounter issues while building from source, consider the following tips:

Ensure all dependencies are correctly installed.
Check for any error messages in the terminal output and search for solutions online.
Make sure you have sufficient disk space for the build process.
If compilation fails, try running make clean before attempting to compile again.

Step 5: Running qView

After successfully installing qView, you can launch it in several ways:

From the terminal, simply type:
```
qview
```
Through the Applications menu: Navigate to Graphics > qView
Using the Ubuntu Dash: Press the Super key (Windows key) and type “qView”

Upon first launch, take some time to explore qView’s interface and features. The application offers a clean, minimalist design that focuses on quick image viewing and navigation.
