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 # (*) see README-pldistros.txt
25 # (*) then you need to run
26 # make stage1=true PLDISTRO=onelab
29 # This build deals with 3 kinds of objects
31 # (*) packages are named upon the RPM name; they are mostly lowercase
32 # Add a package to ALL if you want it built as part of the default set.
33 # (*) modules are named after the subversion tree; as of this writing their names
34 # are mostly mixed case like MyPLC or VserverReference
35 # (*) rpms are named in the spec files. A package typically defines several rpms;
36 # rpms are used for defining DEPEND-DEVEL-RPMS. See also package.rpmnames
38 #################### packages
39 # basics: how to build a package - you need/may define the following variables
42 # a package needs one or several modules to build.
45 # the package's specfile; this is relative to the FIRST module in package-MODULES
46 # see 'codebase' below
50 # (*) package-SPECVARS
51 # space-separated list of spec variable definitions, where you can reference make variable that relate to
52 # packages defined BEFORE the current one (note: you should use = - as opposed to := - to define these)
53 # e.g. mydriver-SPECVARS = foo=$(kernel-rpm-release)
54 # would let you use the %release from the kernel's package when rpmbuild'ing mydriver - see automatic below
55 # (*) package-DEPEND-PACKAGES
56 # a set of *packages* that this package depends on
57 # (*) package-DEPEND-DEVEL-RPMS
58 # a set of *rpms* that the build will rpm-install before building <package>
59 # (*) package-DEPEND-FILES
60 # a set of files that the package depends on - and that make needs to know about
61 # if this contains RPMS/yumgroups.xml, then the toplevel RPMS's index
62 # is refreshed with createrepo prior to running rpmbuild
63 # (*) package-RPMFLAGS: Miscellaneous RPM flags
64 # (*) package-RPMBUILD: If not rpmbuild - mostly used for sudo'ing rpmbuild
65 # (*) package-BUILD-FROM-SRPM: set this to any non-empty value, if your package is able to produce
66 # a source rpms by running 'make srpm'
68 #################### modules
69 # Required information about the various modules (set this in e.g. planetlab-tags.mk)
72 # the complete path where this module lies;
73 # you can specify the trunk or a given tag with this variable
75 # OR if the module is managed under cvs (will be obsoleted)
80 #################### automatic variables
82 # the build defines some make variables that are extracted from spec files
84 # (*) $ make ulogd.pkginfo
85 # to see the list f variables attached to a given package
86 # (*) $ make kernel-devel.rpminfo
87 # to see the list f variables attached to a given rpm
