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-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 mimic what's done for planetlab
33 # (*) then you need to run
34 # make stage1=true PLDISTRO=onelab
37 # This build deals with 3 kinds of objects
39 # (*) packages are named upon the RPM name; they are mostly 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 mixed case like MyPLC or VserverReference
43 # (*) rpms are named in the spec files. A package typically defines several rpms;
44 # rpms are used for defining DEPEND-DEVEL-RPMS. See also package.rpmnames
46 #################### packages
47 # basics: how to build a package - you need/may define the following variables
50 # a package needs one or several modules to build.
53 # the package's specfile; this is relative to the FIRST module in package-MODULES
54 # see 'codebase' below
58 # (*) package-SPECVARS
59 # space-separated list of spec variable definitions, where you can reference make variable that relate to
60 # packages defined BEFORE the current one (note: you should use = - as opposed to := - to define these)
61 # e.g. mydriver-SPECVARS = foo=$(kernel-rpm-release)
62 # would let you use the %release from the kernel's package when rpmbuild'ing mydriver - see automatic below
63 # (*) package-DEPEND-PACKAGES
64 # a set of *packages* that this package depends on
65 # (*) package-DEPEND-DEVEL-RPMS
66 # a set of *rpms* that the build will rpm-install before building <package>
67 # (*) package-DEPEND-FILES
68 # a set of files that the package depends on - and that make needs to know about
69 # if this contains RPMS/yumgroups.xml, then the toplevel RPMS's index
70 # is refreshed with createrepo prior to running rpmbuild
71 # (*) package-RPMFLAGS: Miscellaneous RPM flags
72 # (*) package-RPMBUILD: If not rpmbuild - mostly used for sudo'ing rpmbuild
74 #################### modules
75 # Required information about the various modules (set this in e.g. planetlab-tags.mk)
78 # the complete path where this module lies;
79 # you can specify the trunk or a given tag with this variable
81 # OR if the module is managed under cvs (will be obsoleted)
86 #################### automatic variables
88 # the build defines some make variables that are extracted from spec files
90 # (*) $ make ulogd.pkginfo
91 # to see the list f variables attached to a given package
92 # (*) $ make kernel-devel.rpminfo
93 # to see the list f variables attached to a given rpm
