File structure for release area

Simple but cluttered:

-- builds
   `-- devel
       |-- aPackage
       |-- anotherPackage
       |-- cMsg2et
       |   |-- doc
       |   |-- java
       |       `-- org
       |           `-- jlab
       |               `-- halld
       |   |-- jar
       |   |-- Linux_RHEL6-x86_64-gcc4.8.0
       |   |   |-- bin
       |   |   |-- include
       |   |   |-- lib
       |   |   `-- scripts
       |   `-- src
       |       |-- binsrc
       |       |-- examples
       |       |-- libsrc
       |       |   `-- cMsg2et -> .
       |       |-- scripts
       |       `-- test
       |-- doc
       |-- jar
       |-- Linux_RHEL6-x86_64-gcc4.8.0
       |   |-- bin
       |   |-- include
       |   |-- lib
       |   `-- scripts
       `-- SCONS

Build System

• Based on SCONS and Python/Perl scripts (by Maurizio, Elliott and Dave L).
• Allows for only one library per package, but allows multiple executables and test programs.
• A package may just have a library or executables, or maybe just some include files and scripts.
• System builds libsrc,binsrc and installs libsrc,binsrc,scripts into $INSTALL_DIR (default is package directory).
• Copies include files from libsrc into include directory in $INSTALL_DIR.
• Builds test area but only installs it locally (i.e. ignores INSTALL_DIR env var)
• Ignores any other directories in src (e.g. examples dir).
• Include statements MUST be qualified by package name (e.g. #include <cMsg2et/cMsg2et.h>) (thus the soft link in libsrc dir).

File structure for release area

• Below is a proposed release directory structure.
• Official release area is /gluex/builds.
• Release area only writeable from hdsys account, read-only from all other accounts.
• Package directories are what gets checked into SVN.
• Packages can be checked in/out by anyone.
• Anyone can build and install packages in their own area.
• Only hdsys can release a package into official release area.
• Notes:
  • Should SCONS dir be under packages? Should it be installed?
  • Need to develop scripts to check out and build everything in one command.

-- builds
   `-- devel
       |-- doc
       |-- jar
       |-- Linux_RHEL6-x86_64-gcc4.8.0
       |   |-- bin
       |   |-- include
       |   |-- lib
       |   `-- scripts
       |-- packages
       |   |-- aPackage
       |   |-- anotherPackage
       |   `-- cMsg2et
       |       |-- doc
       |       |-- java
       |           `-- org
       |               `-- jlab
       |                   `-- halld
       |       |-- jar
       |       |-- Linux_RHEL6-x86_64-gcc4.8.0
       |       |   |-- bin
       |       |   |-- include
       |       |   |-- lib
       |       |   `-- scripts
       |       `-- src
       |           |-- binsrc
       |           |-- examples
       |           |-- libsrc
       |           |   `-- cMsg2et -> .
       |           |-- scripts
       |           `-- test
       `-- SCONS

SCONS Scripts

• Need one SConstruct file at the top of all packages.
• SConstruct the same for ALL packages.
• Need SConscript file in each libsrc,binsrc,scripts,test directory.
• SConscript needed to define package dependencies (e.g. determine include paths for compiling).
• Need one Python script per package to define dependencies, where to find header files and libs, etc.

#  SConscript for libsrc
#
#  to customize fill in package dependencies
#
#  ejw, 16-apr-2013
 

Import('*')
from init_env import modify_environment
from util import buildLib


#  set package dependencies
modify_environment(libEnv,'cmsg')



#  build the lib
buildLib(libEnv)

#  SConscript for binsrc
#
#  to customize fill in package dependencies
#
#  ejw, 16-apr-2013


Import('*')
from init_env import modify_environment
from util import buildBin


#  set package dependencies
modify_environment(binEnv,'codaobject cmsg evio et')


#  build programs
buildBin(binEnv)

Python script to define cMsg dependencies:

from util import check_if_dir_exist
import os

def loadcmsg(env) :
	OSENV = os.environ
	CMSG = OSENV['CMSG']
	check_if_dir_exist('CMSG')
	if env['SHOWENV'] == "1":
		print "Loading CMSG software from ", CMSG

	cmsgincs = []
	cmsgincs.append(CMSG + '/include')
	env.AppendUnique(CPPPATH=cmsgincs)

	cmsgldir = []
	cmsgldir.append(CMSG + '/lib')
	env.AppendUnique(LIBPATH = cmsgldir)

	cmsglibs = []
	cmsglibs.append('cmsgxx')
	cmsglibs.append('cmsg')
	cmsglibs.append('cmsgRegex')
	cmsglibs.append('pthread')
	cmsglibs.append('rt')
	cmsglibs.append('dl')

 	env.AppendUnique(LIBS = cmsglibs)
