QtCreator shows error where there's none

[Jaykobb]

Hello everyone !

I've a strange problem and I do not find answers by myself.
I code with QtCreator on a LinuxMint laptop and, with each i work on, QtCreator shows me error where there is none.

Look at this picture above. This is a whole new project for the example. I can build and execute the project properly but still, this is really annoying to have this kind of display while programming. I've opened the same project on a raspi just to see if I had the same display of error, but I had no error on the raspi.

Does anybody has an idea why QtCreator is doing that on my laptop ?

When i look "qtcreator -version" in the terminal it returns me "Qt Creator 4.11.0 based on Qt 5.12.8" and my distribution is "Linux Mint 20 Ulyana"

Thanks for the help,
Have a nice day

In move to Ubuntu 20.04 I had to apt get the Clang 9 version (I think sudo apt install clang-9?) to get rid of spurious Creator marks like this, assuming you're using the default parser of clang in your settings. Might need the same for Mint?

Hello !
Thank you for your help :)
I tried it and several others but nothing really worked. I ended up to purge every packages related to qt and made a whole new installation of QtCreator, so I don't really know where the problem came from.

(Sorry for the laaaaate respond, I had no time to look up after that this month ^^')
