You can safely ignore this warning. Or if you want it gone - update to newer Qt, the warning is popping up only with old Qt versions like Qt 5.12.

Plus please, when you post something on this forum: wrap code in code tags:

```
code();
```

And... if you have a question, ask it. It's not pleasant to guess what the OP might be asking about.

Thank so much for the replay @sierdzio now I am getting following error.

That's completely unrelated. Seems like you accidentally pasted sudo apt install qt511-meta-full into that file. Remove it so that the line reads:

QVariant(const QModelIndex &modelIndex);

and it will work.

Thank you so much @sierdzio for helping me, while building the project accidentlly selected 64bit GCC compiler instead of 32bit arm-gcc. I followed the steps mentioned in here. Now my project builds without any error.
