Resources for Qt Creator

Students in the CS106B/X courses use Qt Creator to write C++ programs. Qt Creator is an integrated development environment (IDE) with tools to edit, build, run, and debug programs.

Installing Qt Creator

Qt Creator is installed on the campus cluster computers. Students may also choose to install Qt Creator on their own computers.

We have prepared installation guides for each operating system, choose the one for your computer. Please follow the instructions carefully and do not skip steps.

After installation, use the check step instructions to build and run our sample project that confirm your Qt Creator is installed properly and works correctly. If you run into problems, check our troubleshooting guide.

Re-installing: If you already have Qt Creator on your computer, ensure it is up-to-date and has the latest bug fixes. To confirm what version you have, look in the Qt Creator menu for "About Qt Creator". The latest version is

Qt Creator 4.12.3 Based on Qt 5.14.2

Note: disregard this section if you are not reinstalling Qt. If you are installing Qt from scratch, click on one of the links above. You will notice that the version you are asked to install looks different from the above version – don't worry about these differences. If you follow our installation instructions you will have the correct Qt version.

Your version number should be equal or greater. If you need to re-install, follow the install steps above, choosing a distinct destination folder for Qt than your existing install. After your new installation is complete, delete the previous Qt folder so you have only one Qt installed on your system to avoid confusion.
