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.

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

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)
