Welcome to the root_serialization wiki!

Building code on Cori

• git clone https://github.com/hep-cce2/root_serialization

• make a separate build directory for out of source build and cd into it.

• module load cmake/3.20.2

• module load cray-hdf5

• module swap PrgEnv-intel PrgEnv-gnu

• We are now using root version built via spack native on Cori (by Patrick Gartung), here is the final cmake command with all the necessary cmake variables:
