Hi all,
I've just repackaged hello using my new proposed source packaging
scheme which does away with dpkg-source and uses just dpkg and
standard .deb files instead.
You can grab the files from:
ftp://ftp.jimpick.com/pub/debian/experimental/hello/
444 Oct 22 14:49 README
17506 Oct 22 14:42 hello_1.3-13.1_i386.deb
4306 Oct 22 14:53 src-deb-hello_1.3-1.1_all.deb
88758 Oct 22 14:54 src-orig-hello_1.3-1_all.deb
To compile:
Install the src-deb-hello_1.3-1.1_all.deb and
src-orig-hello_1.3-1_all.deb files, then make a directory somewhere
and execute:
sudo make -f /usr/src/debian/src-deb-hello/Makefile binary finaldebdir=.
(note: you don't have to be root)
This will create the hello_1.3-1.1_i386.deb binary package.
Then you can use:
sudo make -f /usr/src/debian/src-deb-hello/Makefile debclean
to clean up.
Unfortunately, fakeroot doesn't work for some reason. I suspect that
fakeroot could be fixed.

See, not much there. Nor should there be. The key thing is that it
installs the source tarball into a predictable place - and the control
file contains useful information about where the file came from, and
who put it together.

You will notice that this is essentially the same thing that goes into
the debian directory in a convention debian source package.
I've done several things:
* It is no longer in a subdir off of the base where the upstream source
gets unpacked.
* The debian/rules file is now just called Makefile (a bit less scary to
the uninitiated)
* I prefixed the postinst and prerm with the name of the binary package
they are supposed to go into. It's not absolutely necessary, but I
prefer this when it comes to making multi-binary packages. (I'm a
neat freak)
* !!! A source depedency !!! - well not really, it's just the same old
dependencies we always had. But you can't install this package using
dpkg unless you also have src-orig-hello installed (or you override).
The cool thing is that this package could also declare a dependency to
a binary package (ie. say it needed debmake).
OK. Let's look at the Makefile (formerly debian/rules) where the action occurs:

Ok it's mostly the same, except for a few small differences:
* I made some useful defines at the top, specifically:
srcdebiandir=/usr/src/debian # The predefined place where source
# packages are put on the system. Only root can install source
# packages here (using dpkg). But a user can install the source
# elsewhere using dpkg-deb --extract, and then call
# make srcdebiandir=xxxx to override the source location.
topbuilddir=$(shell pwd) # where the source is unpacked and
# temporary files are put - this defaults to the current
# directory but can be easily override by supplying a
# parameter to make (ie. you might have a prefered temp dir)
srcdebdir=$(srcdebiandir)/src-deb-hello # Just the location of
# this particular package.
finaldebdir=.. # Where you want the final .deb containing
#the binary files to land. Perhaps this should default to "."
* The default rule is build. Seems like a good starting point.
* An additional rule: unpack - pretty clear what this does. Source
is kept in packed up tarballs in the source packages, and is only
unpacked on a temporary basis under the $(topbuilddir) which
is usually the current directory owned by the user making the
package. There is no reason to unpack things in the same
directory as the debian-specific files (as we currently do now).
In this example, I unpacked to a directory called hello.src -
that just me being a neat freak again.
So the upstream source can be anything (ie. .src.rpm's), since
the packaging system doesn't unpack them - only the rules the
maintainer puts into the Makefile really matter.
* OK, I didn't do this since hello didn't need to be patched. But
if it did - I was just add another step to unpack (or maybe even
a new rule) which would just apply a patch located in
$(srcdebdir) or below to the unpacked source. Yes, Virginia,
you can include debian-specific binary files using this
source packaging format.
* Another additional rule: debclean - just calls make clean and
additionally nukes the temporary source directory created by
unpack.
* The binary rules installs everything into a temporary subdir
called hello.build. I'm just being neat again.
The rest of it is pretty standard. Additional parameters needed to
be given to dpkg-shlibdeps and dpkg-gencontrol since I am no longer
using the default locations for the control, files, and changelog
files.
The only thing missing from the mix was the utilities for creating
source packages automatically. I just created a directory structure
and control file by hand, and used dpkg-deb --create to make them.
It was really easy, since the source packages are extremely
unsophisticated.
OK, that's it. Tell me how you like it. I know I like it. :-)
Cheers,
- Jim
