ROOT on macOS 15 / Xcode 16

ROOT
8

Hi James,

Thanks. The culprit seems to be /Library/Developer/CommandLineTools/usr/bin/../include/c++/v1 . If you look in that directory, you probably will not find traces of coroutine.

A possible way out could be to a) remove the existing CLT(s) on your system b) install apple clang 16 CLTs from scratch. You can find on the web several fora that explain how to do that. I report here one possible solution that worked for our CI nodes:

  1. backup and remove the directory /Library/Developer/CommandLineTools
  2. softwareupdate -i "Command Line Tools for Xcode-16.0"

I am happy to answer with something that worked for me but please note that this is more of a macOS question than a ROOT one.

Cheers,
Danilo
