10 # this extracts all specfiles and computes .mk from specfiles
11 # you need to specify PLDISTRO here if relevant - see below
13 # for more info on how to invoke this stuff
15 #################### (fedora) distributions
17 # (*) as of nov. 2007, myplc-devel is deprecated
18 # (*) instead, we create a fresh vserver that holds required tools (see e.g. planetlab-fc6-devel.lst)
19 # (*) the build uses the current fedora version as a target for the produced images
20 # (*) so you simply need to create a fedora 8 build image for building fedora-8 images
22 #################### (planetlab) distributions
24 # (*) the default distribution is called 'planetlab'
25 # (*) you may define an alternative distribution, e.g. onelab
26 # in this case you need to
27 # (*) create onelab.mk that defines your *packages* (see below)
28 # (*) create onelab-tags.mk that defines where to fetch your *modules*
29 # (*) create your main yumgroups.xml as groups/<distro>.xml
30 # (*) there are also various places where a set of modules are defined.
31 # check for .lst files in the various modules that build root images
32 # and mimick what's done for planetlab
33 # (*) then you need to run
34 # make stage1=true PLDISTRO=onelab
37 # This build deals with 2 kinds of objects
39 # (*) packages are named upon the RPM name; they are moslty lowercase
40 # Add a package to ALL if you want it built as part of the default set.
41 # (*) modules are named after the subversion tree; as of this writing their names
42 # are mostly mixedcase like MyPLC or Vserverreference
44 #################### packages
45 # basics: how to build a package - you need/may define the following variables
48 # a package needs one or several modules to build.
51 # the package's specfile; this is relative to the FIRST module in package-MODULES
52 # see 'codebase' below
56 # (*) package-SPECVARS
57 # space-separated list of spec variable definitions, where you can reference make variable that relate to
58 # packages defined BEFORE the current one (note: you should use = - as opposed to := - to define these)
59 # e.g. mydriver-SPECVARS = foo=$(kernel-rpm-release)
60 # would let you use the %release from the kernel's package when rpmbuild'ing mydriver - see automatic below
62 # a set of *packages* that this package depends on
63 # (*) package-DEPENDFILES
64 # a set of files that the package depends on - and that make needs to know about
65 # if this contains RPMS/yumgroups.xml, then the toplevel RPMS's index
66 # is refreshed with createrepo prior to running rpmbuild
67 # (*) package-RPMFLAGS: Miscellaneous RPM flags
68 # (*) package-RPMBUILD: If not rpmbuild - mostly used for sudo'ing rpmbuild
70 #################### modules
71 # Required information about the various modules (set this in e.g. planetlab-tags.mk)
74 # the complete path where this module lies;
75 # you can specify the trunk or a given tag with this variable
77 # OR if the module is managed under cvs
82 #################### automatic variables
84 # the build defines the following make variables - these are extracted from spec files
85 # (*) package-TARBALL : from the Source<n>: declaration
86 # example: kernel-i386-TARBALL = SOURCES/linux-2.6.20.tar.bz2
87 # (*) package-SOURCE :
88 # example: kernel-i386-SOURCE = SOURCES/linux-2.6.20
90 # example: kernel-i386-SRPM = SRPMS/kernel-2.6.20-1.2949.fc6.vs2.2.0.1.0.planetlab.src.rpm

96 # RPMS/i686/kernel-debuginfo-2.6.20-1.2949.fc6.vs2.2.0.1.0.planetlab.i686.rpm
97 # (*) package-rpm-name
98 # example: kernel-i386-rpm-name = kernel
99 # (*) package-rpm-release
100 # example: kernel-i386-rpm-release = 1.2949.fc6.vs2.2.0.1.0.planetlab
101 # (*) package-version
102 # example: kernel-i386-rpm-version = 2.6.20
103 # (*) package-subversion
104 # example: myplc-rpm-subversion = 15
