(Qt Creator works perfectly on Ubuntu 19.10)

Qt Software Development Kit (Qt SDK) includes Qt Creator IDE & Qt Framework Libraries with Full Code Examples among other things. On Ubuntu 19.10, if you want to develop GUI applications with Qt, you need to install that Qt SDK first with a C++ compiler. Installing it on 19.10 is slightly different to different to 18.04 as this involves configuring GNU GCC C++ compiler on 19.10. After setup, you will have a ready, complete Qt SDK with Creator, Designer, Linguist, and Assistant works with G++ compiler. I hope this will be useful for you all. Happy hacking!

Install Compiler

The compiler is called g++:

$ sudo apt-get install g++ 

Install Qt SDK

This is the complete Qt with all tools and source code examples:
$ sudo apt-get install qt5-default qtcreator qtbase5-examples qtbase5-doc-html

Configure Qt Creator

  • Go to Tools > Options.
  • Go to Kits > Kits tab > select Manual, Desktop kits > see section Compile: > see C++ > change the selection from Clang to GCC C++ 64-bit.
  • OK.


After all steps above you should be able to do everything with Qt programming like below.

Testing the examples:
All source code examples should be visible at main page.

Testing the tutorials:
Same as code examples, all tutorials should be visible as well at main page.

Testing build code examples:
Just pick an example from a lot of examples available and then build (Ctrl+R, or green '>' button). It should be successfully compiled. See example below. Until this point, Qt SDK is ready for you to start coding. Enjoy!

Happy hacking!
