multiple warnings when compiling a project

Good morning everyone,

I'm new to this forum, so please excuse any mistakes I might make.

I recently installed the ARM GNU compiler, and since then, I've been encountering some warnings in my console during compilation. I'd like to resolve or eliminate them if possible. Can anyone offer assistance?

Here are the warnings I'm seeing:

Could someone kindly guide me on how to address these warnings or suppress them? Any help would be greatly appreciated.

Thank you.
