Thank you for the interest in GlobalModulesIndex project at HSF group! As this project is highly technical, it is necessary to have some understanding of ROOT and Clang before starting to write proposal. This document is dedicated to give a surface introduction of C++ modules, and to give a project which you can try out.
Build ROOT with C++ Modules
git clone https://github.com/root-project/root mkdir root-build cd root-build cmake ../root -Druntime_cxxmodules=On -Droot7=Off (-GNinja) make (or ninja)
