© 2006 UC Regents2 Prepare for the build  Check out CVS Rocks distribution:  cvs - login  cvs - checkout -r ROCKS_4_1 rocks  Go to the top-level rolls directory:  # cd rocks/src/roll  # ls bin/ cacl/ etc/ hpc/ patch/ birn/ condor/ gfarm/ intel/ nbcr/ birn-oracle1/ CVS/ grid/ java/ ninf/ …

© 2006 UC Regents3 Create new roll directory  Prerequisites  name  version (or defaults to 1) a-17beta  color (or random choice from X colors)  Creation  # cd rocks/src/roll  # bin/make-roll-dir.py -n cacao -v c chocolate  # ls cacao graphs/ Makefile nodes/ src/ version.mk

© 2006 UC Regents5 Clean new roll directory  Remove template’s id entries old: # $Id: Makefile,v /12/01 01:31:55 nadya Exp $ new: # $Id: $  Remove template’s log entries old: # $Log: Makefile,v $ # Revision /12/01 01:31:55 nadya # baseline new: # $Log: $

© 2006 UC Regents6 What to clean?  Makefile  graphs/default/cacao.xml  nodes/cacao.xml  src/Makefile  src/cacao/Makefile  src/usersguide/Makefile  src/usersguide/roll-cacao-usersguide.in

© 2006 UC Regents7 File graphs/default/cacao.xml  the file describes how all the files in the nodes directory are linked together in the kickstart graph  specify edges from known nodes to cacao node  for graph file syntax see guide/4.1/kickstart-xml.html

© 2006 UC Regents8 Add edges in graphs/default/cacao.xml cacao Roll $Log: cacao.xml,v $ root client cacaointel server …… condor

© 2006 UC Regents9 File nodes/cacao.xml  the files in nodes/ are used to install packages and to configure their respective services  for nodes files syntax see guide/4.1/kickstart-xml.html

© 2006 UC Regents10 Add packages in nodes/cacao.xml Extension to Java beans, for internal consumption only. $Log: cacao.xml,v $ cacao roll-cacao-usersguide package name equals spec file name

© 2006 UC Regents11 src/cacao/  # cp /Venezuela/Chuao/cacao tar.gz. Makefile cacao tar.gz cacao.spec.in version.mk  Makefile PKGROOT=/opt/cacao … install:: mkdir -p $(ROOT)/$(PKGROOT) ( cd $(NAME)-$(VERSION); make prefix=$(ROOT)/$(PKGROOT) install; ) build: gunzip -c $(NAME)-$(VERSION).tar.gz | tar -x ( cd $(NAME)-$(VERSION);./configure --prefix=$(PKGROOT); make; )  version.mk NAME = cacao RELEASE = 0 VERSION = 15.44

© 2006 UC Regents12 Caution!  Naming convention is important cacao tar.gz will fail !  Why? $(NAME)-$(VERSION) combo NAME = cacao cacao VERSION =  Fix  NAME = cacao VERSION = cacao_15.44.tar.gz ---> cacao_15.44/ $(NAME)_$(VERSION)  NAME = Cacao VERSION = 15.44
