history
Project history and usage
CLHEP is CERN's Class Library for High Energy Physics, a C++ collection of foundation and utility classes for high-energy-physics software. Its official project page describes packages for random generators, physics vectors, geometry, linear algebra, units, and related HEP building blocks.
Project history
The CLHEP project was proposed by Leif Lonnblad at CHEP 92. CERN's project page presents it as a set of independent HEP-specific foundation and utility packages, with inter-package dependencies allowed only under defined conditions.
The project later moved to CERN GitLab and is maintained as a source-buildable CMake project. The official README documents a modern C++ build, package-config scripts, CMake imported targets, and pkg-config files for both the full library and component libraries.
Adoption history
CERN's CLHEP page explicitly ties a large fraction of contributions to use in BaBar, the Geant4 Collaboration, and Fermilab's ZOOM project, especially in the Random, Vector, Geometry, and Matrix packages.
The same page notes that CERN LCG formally maintains CLHEP and that HepMC, HepPDT, and StdHep migrated out as standalone external LCG packages, placing CLHEP in the long-running HEP software stack rather than as a one-off library.
How it is used
Users typically consume CLHEP as a compiled C++ dependency, either linking the whole CLHEP library or individual packages such as Vector and Random. The README documents `clhep-config`, package-specific `*-config` scripts, CMake `find_package(CLHEP REQUIRED)`, imported targets, and pkg-config integration.
The Homebrew package exposes the library's config helper executables, which is exactly the sort of package-manager surface used by downstream build systems to discover compiler and linker flags.
Why package nerds care
CLHEP matters to package maintainers because it is old scientific infrastructure with ABI, compiler, CMake, pkg-config, and downstream experiment compatibility concerns. It is less a flashy CLI than a dependency that makes physics software stacks build reproducibly on Unix-like systems.
Its formula also illustrates a common scientific-packaging pattern: a library package ships many small `*-config` helper commands that bridge older build expectations and newer CMake/pkg-config workflows.
