Build all the things with Spack: a package manager for more than C++
summary
Spack is a Python‑DSL package manager that builds combinatorial variants — e.g., install HDF5 with specific GCC 8.3, MPI, BLAS/LAPACK and target CPU like Skylake — by hashing installs into isolated directories and recording full build metadata. It already serves supercomputers like Fugaku, supports build matrices that generate tens or hundreds of builds and CI jobs, produces reproducible manifests and lockfiles, and claims 4,300 packages with over 600 contributors; Windows support is planned.
