2. GLAST CHEP 03 March 24-28 2003 T.Burnett2/14 Introduction Objective: make HEP software developers more productive HEP software development components: –Package: group of related source files, usually to build a single library and/or executable Versioning via cvs tags –“Release” system to manage and build executables from set of tagged packages –Development scheme: “Test area” mechanism for developing and testing new code against a release. Observations: The release/management systems are command-line oriented, can be daunting to new developers Hard to get overall view, especially when dealing with multiple packages

5. GLAST CHEP 03 March 24-28 2003 T.Burnett5/14 An OO analysis: The players Objects: –Environment: CMT env vars, etc. –CMT packages system (read-only, sticky tags) development (head versions) requirements files, sources –binaries: libs, dlls, exes Tools: –CMT –CVS –development tools Windows: Visual Studio Linux: gmake, emacs, gdb/ddd –Doxygen

6. GLAST CHEP 03 March 24-28 2003 T.Burnett6/14 The strategy Present the user with a view of all the objects Allow appropriate tools to be used according to development scenarios: –set environment –checkout packages, singly or in groups –browse set of available packages –examine properties of each package, relationships –modify and rebuild binaries –check in and/or tag new versions –run executables
