Makefile targets: tar & rpm pkgs, while using O=<dir> as non-root

Makefile targets: tar & rpm pkgs, while using O=<dir> as non-root

[Linda Walsh]

Unpacked 2.6.13.3 and made it read-only.

Using the "O=" param, built output tree for another machine as
a non-root user.

I wanted to create an installable kernel & module package to copy
to the new machine & install.

I noted new targets:
    binrpm-pkg [& rpm-pkg], and
    tarbz2-pkg [& targz-pkg, & tar-pkg].

Both seem to fail either for reasons that appear to be related to
not honoring the "O=" param, or attempting to actually install into
the root of my build-machine.

Should these targets work or have they not yet been converted to work
within the "O=" framework?  In cases where the Makefile is attempting
to install into "<Root>/boot" or "<Root>/lib/modules" ,should I
expect the output to appear in "$O/boot" and "$O/lib/modules/"?

Please Cc responses to me, in addition to list, thanks.

I've not really used out-of-tree building for Linux, so the tar*
targets are probably not really tested with that regard. Though I'll
check that and see if it works (of if a patch is needed.)

The RPM targets have to be tested by somebody else :)

Thanks -- the error I got for the "tar"-based images started as:

==========

Briefly, the make rpm-pagage options call "make install" and
"make modules_install".  Both attempt to install the kernel
for the "target" system onto the the "Build" system.  This isn't
desired as the "target" kernel won't even run on the "build"
system.

I could supply error listings, but it seems unneeded as it is
so easily reproduced.

I see JanB is on the making "tar" image, but how long ago was
building of the rpm stuff done?  Is it the case that the designer/writer
of that hasn't had time to make it work with the "O=" param?  Is
someone still actively maintaining those targets?

Ideally it would be good to be able to make an installable kernel
package as a non-root user.  The idea is to not need root-privs
except to install, right? :-)

That's how it is ment to be. Actually, for in-tree builds, you get the
tarball without first becoming root. I'll fix that soon, as I find
some spare minute to hack it :)

    So I see.  Slight minor possible "nit".
I have a suffix (CONFIG_LOCALVERSION) set.
While the tar picks up the /lib/modules files in <ver>-suffix, the
map and vm files all have suffixes w/o the "localversion" appended.
This doesn't seem desirable, eh?:

S'okey...I can at least use the above to xfer files over for now...

Given the existence of `cp -al', I'm not quite sure what the point of
out-of-tree building *is*. (I'm equally mystified by srcdir!=objdir
builds; I can see their utility for software with many generated files
and multi-stage bootstraps, like GCC, 'cos they simplify the makefiles,
but for normal software? What's the point?)

I mean, instead of

cd linux-2.6.blah
make blah O=/some/directory

you can always do

cp -al linux-2.6.blah /some/directory/
cd /some/directory
make blah

unless you're so short of space that you can't store the object files
and the source files on the same disk, and that should be a *very* rare
complaint with today's disk sizes.

Consider following use cases:
1) Src located on NFS mounted filesystem
2) Src on RO media
3) Src on another filesystem
4) Builds for several architectures from same source base
5) Builds for several different configurations
etc.

It is convinient in many places. Maybe not for you but for others.

Look at the "deb" target for how this was fixed for building Debian
(-style) packages.

Specifically, you want to change:
	$(MAKE)
to
	$(MAKE) KBUILD_SRC=

At a glance, I don't see a similar problem in the binrpm-pkg target, and
I don't understand the rpm target at all, so those may have other
issues.

I am, however, looking at 2.6.15-rc{something}, not 2.6.13, but I think
it's been a while since Sam sent the deb packages fixes upstream.

That was second time I did it. It took considerably longer the first

Nothing wrong with that. NFS is fast for me.

(Admittedly, on heavily contended networks you're right.)

*Good* reason (one that unionfs would solve, but still...)

cp -al

There were a couple of compelling arguments in there. :)

... apply a patch and watch the resync hell.  That really, really doesn't
work well enough for use when doing any kind of development.

Well, personally I handle patch-application in cp -al'ed trees by doing
cp -al via a script, and repatching all currently hardlinked trees
(obviously if they are very divergent some patches will fail and I'll
have to fix them up by hand).

It works for me well enough to keep hardlinked branches going for in
some cases years without problems.

(On top of that, I've sometimes considered a switch to patch(1) that
switches to truncate-and-rewrite rather than unlink-and-replace. Haven't
implemented it yet though.)


(And if you're using this to maintain development branches, then you
have resync and conflict-management problems *anyway*, which this makes
no worse.)

... then you edit a file to fix a typo, and have a _nice_ day next Friday
when you notice that stuff got out of sync.

Yes, but it's easier to deal with when the number of your repositories
doesn't get multiplied by factor of 20 or so...

Well the O= syntax is much nicer when using Git.   You symply checkout the
branch you're interested in and compile it; then switch to another,
compile it, etc...  Git makes checking out a brach lightning fast, it's
very slick.   Using the O= notation means you only have one branch checked
out at a time and there's no need to have source files linked to a bunch
of different directories.

Cheers,
Sean

Your text editor is insufficiently flexible. Mine can snap hardlinks
automatically when st_nlink > 1. :)

(But let's avoid editor wars. I'm sure there's a magic way vim can be
coerced into doing things properly.)


What we really need is an FS that does behind-the-scenes block CoW
and/or block merging anyway; then we could just cp -a the damn tree
and keep the space savings.

Er, I don't have a factor of 20 more repositories than anyone else. (I
don't have the disk space for that!)

A much easier way is to use:

  version="${KERNELRELEASE}"

A patch for this is already in -mm, I expect/hope Linus will pick it up
after 2.6.15.
