We are proud to announce that Qt Online Installer and Maintenance Tool 4.0.1-1 have been released today. This version allows open-source users to select a mirror to download packages and their metadata. In addition, a bunch of fixes have been done to the installer UI.

Below are basic instructions for installing on Linux that may work for your system, however, we are unable to provide further Linux support. If you are unable to get Qt Creator working on your Linux system, please consider using another computer or working on a campus cluster computer.

1) Install prerequisites

If you're running Ubuntu, Debian, Mint, or any other Debian derivative, you can install the needed components using the apt package manager. Issue the following commands below in your shell.

The first command ensures your package manager is up-to-date:

This command installs the tools and libraries needed for Qt (be sure to copy/paste the entire line, it is long!)

If you're running some other variant of Linux, figure out a way to install the tools make, g++, and gdb.(For example, on Fedora / Red Hat systems, you may be able to use the yum package manager.)

2) Download installer

The Qt Creator official download site is https://www.qt.io/download-qt-installer.When you go to this site, it should detect that your computer is running Linux and recommend the installer 'Qt Online Installer for Linux'. Click the green 'Download' button to download the installer.

3) Run installer

The downloaded installer is named something like qt-unified-linux-x64-version-online.run and is likely located in your ~/Downloads directory. Use chmod+xqt*.run to make the file executable, then run it by typing ./qt*.run.

The graphical installer launches and walks you through a set of steps. For most steps, you can use the default settings and simply click 'Next' or 'Agree' to move on, with the following exceptions:

• At the Qt Account step, you will have to create your own Qt Account.
• At the Select Components step:
  • Select the highest-numbered Qt version. For Winter Quarter 2021, the version number must be at least Qt 5.15.0, but must not be any version starting with 6 (e.g. do not install version 6.0.0). Do not select any version labeled 'Preview' or 'Alpha' or 'Beta'.
  • IMPORTANT: You must also select the Desktop gcc kit component. Expand the 'Qt' triangle, then expand the triangle with Qt version number, then click the checkbox labeled 'Desktop gcc'. See the screenshot below.

(The screenshot has part of the version number scribbled out since the versions change so frequently; it is just shown as a general example of what the UI will look like.)

3) Install CS106 specific components

After installing Qt, you must install the CS106-specific components and do a complete build and run cycle to confirm all is working properly.

Download CS106 project and extract

• Download this archive file: 📦 CS106.zip
• Un-zip the download contents (on a Windows computer, click 'Extract all') to a location of your choice. You should have a folder named CS106 with several files and folders inside.

Open and configure CS106 project

A Qt Creator project includes a file named with a .pro extension. Double-clicking the .pro file opens the project in Qt Creator.

• Find the CS106.pro file and open it now.

• When opening a project for the first time, Qt Creator brings up a 'Configure Project' panel for you to select the appropriate build kit (see screenshot below). The default kit should already be selected; it will match the component you selected when installing Qt Creator. Accept the default by clicking the 'Configure Project' button.
• If no kits are shown as available, review the Qt install instructions. You can repeat the steps to re-install if you missed selecting the required components.

Build the program

C++ code must be compiled or built before it is run; this means converting the source code into executable binary code.

• Click the Build icon in the lower-left of the Qt Creator window.
• Watch the build progress meter in the lower-right. The first time you build a project, it can take a minute or more to compile the library code. When the bar turns green, it indicates the program successfully built.

Run the program

Now that the program is built, you are ready to run it.

• Click the Play/Run icon in lower-left of window.

• As shown in the screenshot below, the welcome program prints a message to the console window and draws the Stanford logo on graphics window.

✔️ Congratulations, your installation is good to go! You may now discard the CS106 project, you will not need it again.

5) Configure settings (optional)

For a better experience, we suggest changing some of the default settings, see our recommended configuration settings.

Qt's support for different Linux platforms is extensive and mature.

To download and install Qt for Linux, follow the instructions on the Getting Started with Qt page.

Supported Configurations

The following configurations are supported.

Requirements for Development Host

The Qt installers for Linux assume that a C++ compiler, debugger, make, and other development tools are provided by the host operating system. In addition, building graphical Qt applications requires OpenGL libraries and headers installed. Most Linux distributions do not install all of these by default, but setting up a development environment is still straightforward.

Use the following commands to install the basic requirements for building Qt applications:

Debian/Ubuntu (apt-get)

Fedora/RHEL/CentOS (yum)

openSUSE (zypper)

Building Qt 5 from Source

You can also build Qt 5 from the source package and configure it according to your target platform. The source packages are obtained from http://www.qt.io/download/.

Below, you will find more information about building Qt from source.

Deployment and Other Issues

The pages below covers specific issues and recommendations for creating Linux/X11 applications.

Where to Go from Here

We invite you to explore the rest of Qt. We prepared overviews which help you decide which APIs to use and our examples demonstrate how to use our API.

• Qt Overviews - list of topics about application development
• Examples and Tutorials - code samples and tutorials
• Qt Reference Pages - a listing of C++ and QML APIs
• Qt X11 Extras - provides additional APIs for X11

Qt's vibrant and active community site, http://qt.io houses a wiki, a forum, and additional learning guides and presentations.
