Use of a Configuration Management Tool in LHCb Software

Florence Ranjard

Speaker: Florence Ranjard

  The currently maintained LHCb software comprises some legacy code, a set of packages written in Fortran, a new Framework written in C++ (GAUDI), as well as many 3rd party packages. A process for managing the physical organisation of packages and their interdependencies has been developed that takes into account the collaborative and distributed nature of the development team. A major requirement has been the ability to allow packages with dependencies to other packages to evolve at different speeds, such that developers might release their packages at any time without disturbing the main line. The software is managed in a CVS repository and a configuration management tool (CMT by C.Arnault/LAL) has been employed for managing new releases. This tool enables users to generate makefiles in view of building libraries and applications from packages residing in their working area, in the release area or in an external area. The tool also permits the librarian to make public releases on various platforms, including various UNIX flavours and NT. This paper describes the physical organisation of LHCb software packages and summarises our experience with CVS and CMT.
