In preparation for the post-LHC era, the Future Circular Collider (FCC)
Collaboration is undertaking design studies for multiple accelerator
projects with emphasis on proton-proton and electron-positron high-energy
frontier machines. From the beginning of the collaboration, the development
of a software stack with common and interchangeable packages plays an
important role in simulation, reconstruction or analysis studies. Similarly
to the existing LHC experiments, these packages need to be built and
deployed for different platforms and compilers. For these tasks FCC relies
on Spack, a new package manager tool recently adopted by other experiments
inside the High-Energy Physics (HEP) community. Despite its warm adoption,
the integration of Spack with CVMFS for software distribution, while
already possible, exposes some limitations. This talk provides an overview
of these difficulties in the context of the FCC Software.
