Biweekly meeting: C++ Modules in ROOT

Wednesday 16 Oct 2019, 14:00 → 15:00 Europe/Zurich

Oksana Shadura (University of Nebraska Lincoln (US)), Vasil Georgiev Vasilev (Institute for Advanced Physical Studies (BG))

Attendance: Axel, David, Oksana, Vassil

Axel: Nothing modules related. I will come back to it in a few days.

David: I am busy with other things.

Oksana: We need the modules IB soon. I am fixing random issues which should be fixed in the ROOT master. I am dealing with MakeProject incremental failures. Axel: what about generating the modulemap in a subdirectory. Wouldn't that fix it? Oksana: we will give it a try.

Vassil: We have enabled C++ modules by default for C++11 and C++14. So far a few issue reports but nothing major. Couple of days ago we enabled C++ modules for C++17. We expect this to affect CMS, LHCB and ALICE -- they build their stacks in C++17 mode and they will . Fixed the genreflex vs rootcling differences by introducing rootcling -reflex flag which makes rootcling to behave as genreflex. Fixing the case where the ROOT modulemap is found in two different places (ROOT-10354) https://github.com/root-project/root/pull/4553 Following up with the Google folks on the arm modules issue.
