The packaging of glastsim with CMT

1
The packaging of glastsim(with CMT)

• This is an update from a talk I gave 2 weeks
  ago
• (Even more) Help and suggestions from Traudl and
  Sawyer
• New emphasis on adoption of CMT

2
Objectives

• Reorganize the current glastsim code into
  packages
• Make them shared libraries
• Define a package-oriented development environment
  that generates MSVC project files and unix make
  files from a common description

Example disk structure
root has package name
Version name root for clients
Documentation
Public header files

After packages root
analysis/ geometry/ glastmedia/
readout/ application/ geomrep/
graphics/ reconstruction/ data/
gismo/ instrument/
xml/ facilities/ glast_settings/
level2/ flux/ glastflux/ merit/

• Root directory has only package roots
• Special package glast_settings has over-all
  build instructions

6
Some changes

• gismo
• Contains egs, gheisha, and PEGS4
• graphics
• Contains windows, motif, batch, control
• facilities
• New xml split off

7
The uses tree (partial)
application
reconstruction
glastflux
data
level2
flux
readout
instrument
analysis
geometry
8
A lot to do

• reconstruction and instrument still need
  splitting apart
• application is top-heavy
• need to rethink user interface stuff

9
Status ( 6 Jan 2000)

• Glastsim (gui and console versions) and merit
  both function as before
• Unix make works with cygwin (just console)
• CMT needs GLAST-specific tools and documentation

10
Continuation 20 Jan 2000

• Some To-dos still to do!
• Set of packages (v1) almost ready to checkout
• Many of Traudls suggestions implemented
• Interface classes weaned
• Javadoc comments set for several packages (and
  tested with Doxygen).
• see http//glast.phys.washington.edu/burnett/gism
  o/html/
• Extensive development of Visual Studio fragments

11
The package model a tree
server
server
server
server
uses, or depends on
Joe package
provides services for
client
client
client
client
12
So what does uses mean?

• Version modifier
• Compile time dependencies
• include paths
• preprocessor defines
• Link time dependencies
• Library paths, lib names
• (so package must create its binaries, or
  constituents )
• Execution time dependencies
• Shareable paths, names
• Environment variable definitions, e.g., to data
  files
• Alias names

13
About CMT (Configuration Management Tool)

• Special folder mgr contains two primary files
• requirements complete description of interface
• Makefile standard user-added targets
• Executable cmt a parser of this file allowing
• query
• building other files
• make
• DevStudio
• any document
• References

CMT query example

• cmt show uses
• use geometry v0
• use glast_settings v0
• use CLHEP v1r4
• use graphics v0
• use glast_settings v0
• use CLHEP v1r4
• Selection
• use CMT v1r3 /packages
• use CLHEP v1r4 /packages/
• use glast_settings v0 /packages/
• use graphics v0 /packages/
• use geometry v0 /packages/

16
Creating a Visual Studio project

• cmt build msdev

17
Creating unix make files

• make

Status and Plans

• Packages are currently in cvs under cmt
• Plan to move to packages for development release,
  in next few days
• Will include a setup script that now exists
• Implements sharable libraries (dlls)
• BUT
• Release strategy not clear
• Unix not ready

20
Unix plans

• cygwin success is a proof of principle
• No special modification!
• Linux does not yet work (cursory look)
• Surprising, since VC and cygwin worked
  immediately
• Need someone to
• Understand principles
• Formulate implement policies
