Special topics
Presentation by Pavlo Svirin: Modular builds for ROOT
Questions:
* Jakob: make menu config thing, can this only work with cmake?
- for now it was just a test?
* what about ninja? - difficult to use, ninja doesn't support the job server, can't use the resources efficiently
* Danilo:
* after Bertrand is back -- contact him - he is the CMake person in the team
Status of macos15
* C++ standard library in macos was changed
* requires clang 16 and later
* module map file for 14 and 15
* backport from llvm 17
* 6.28 and 6.30 - disable macos15 in the CI
* can it work with conda? - maybe, to be tested
* if we want to support macos native, we will need to update llvm every year
Round table extras
* Vincenzo -
* CMS Combine built on top of 6.30
* but they want to try to work with 6.30.08 on conda instead of jumping 6.32.02 on conda?
* Jonas Rembser needs to help as the issue is with the fits convergences
* conda does cross compilation on linux -- nice for CI testing
