QtCreator can't find headers (stm15 target)

Dallas Posey

Hi. I installed QtCreator using instructions here: Digi stm157 Install QT. I can create a project and it will compile and run on the target. But the linter doesn't seem to be using the right headers. I know this is common problem, but the solutions seem to be all over the place and none I've tried have been successful. I think the kit is at least marginally right because the compile step output looks right:

and like I said, it runs on the target hardware as expected. Here is a screenshot of the offensive editor window:

I did add a link to the SYSROOT in the Kit Manager:

as it was empty out of the box and after I added that there were less errors, but it is clearly not right, just wrong in a different way.

The host in my case is Ubuntu 22.04 and I am running version 9.02 of QtCreator (per Digi's instructions). The environment vars from the shell all look to be appropriate for the toolchain etc.

I guess what I'm really wondering is how the IDE determines where to find the header files etc it uses for linting and how I might go about configuring them properly.

Thx for any suggestions,

As an update, I installed qtcreator from the ubuntu repo (13.0.2) and it works much better. Are there config files somewhere I can diff against the previous install to better understand the original problem?
