Re: Lots of warnings when compiling a project using ROOT 5.26.00a

Hi Constantin,

How are you getting those error messages?

Note that both those messages are accurate but can not (to my knowledge) be removed
as they are a reflection of implementation choice that we have intentionally made (i.e. removing them would require removing functionality from the interfaces).

Cheers,
Philippe.
