Hi Fabian,
To run code on Linux platforms, including the ArcGIS Runtime SDK for Qt samples, source the init script for the target platform before opening Qt Creator. This means that you will need to open a terminal and use one of the following init file depending on the platform that you are on and the type of the terminal that you are using:
- init_sdk_qt64.sh for 64-bit bash,
- init_sdk_qt32.sh for 32-bit bash
- init_sdk_qt64.csh for 64-bit C shell
- init_sdk_qt32.csh for 32-bit C shell.
After that you have ran the above script located in the root folder of your installation, use the same terminal to start your QtCreator.
Let me know if you have more questions.
