Vision for ROOT7

Shift Handover

• Problems on macOS and with CMake 4
  • Question about fix: is the fix regarding CMake policy versions sustainable?
  • Bertrand and Olivier started debugging, PR work-in-progress
• Problem with Homebrew:
  • Build with old SDK, doesn't work with latest version installed by user
  • Way forward (?): Homebrew needs to update their SDK, then at least the combination of latest versions will work
• Builds mostly, some temporary issues

Meeting Summaries and Plans

• PPP: Bernhard's rehearsal for PhD defense
• I/O meeting: contact with NGT students in CMS, SoA work in RNTuple and compression

Topics: Status for 6.36

• master branch locked, v6-36-00-patches will be created next week
• see Google Docs for list of PRs
• (incomplete) list of missing things:
  • moving RNTuple out of v7
  • DistRDF out of Experimental + fixes for discovered issues
  • PR by Jamie

Round Table

AOB

• Cron job to synchronize Cling changes to https://github.com/root-project/cling currently gone
