	1614
	1615	debbuild - Build Debian-compatible packages from RPM spec files
	1616
	1617	=head1 SYNOPSIS
	1618
	1619	debbuild {-ba\|-bb\|-bp\|-bc\|-bi\|-bl\|-bs} [build-options] file.spec
	1620
	1621	debbuild {-ta\|-tb\|-tp\|-tc\|-ti\|-tl\|-ts} [build-options] file.tar.{gz\|bz2}
	1622
[55]	1623	debbuild --rebuild file.{src.rpm\|sdeb}
[22]	1624
[89]	1625	debbuild --showpkgs
	1626
[22]	1627	=head1 DESCRIPTION
	1628
[55]	1629	This script attempts to build Debian-friendly semi-native packages from RPM spec files,
	1630	RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
	1631	options rpmbuild does, and should be able to interpret most spec files usefully. Perl
	1632	modules should be handled via CPAN+dh-make-perl instead; Debian's conventions for such
	1633	things do not lend themselves to automated conversion.
[22]	1634
[55]	1635	As far as possible, the command-line options are identical to those from rpmbuild, although
[57]	1636	several rpmbuild options are not supported:
[22]	1637
[57]	1638	--recompile
	1639	--showrc
	1640	--buildroot
	1641	--clean
	1642	--nobuild
	1643	--rmsource
	1644	--rmspec
	1645	--sign
	1646	--target
	1647
	1648	Some of these could probably be trivially added. Feel free to send me a patch. ;)
	1649
	1650	Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
	1651	you'll have to make heavy modifications anyway.
	1652
	1653	If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
	1654	promise I'll do anything other than say "Yup, that's broken" or "Got your message".
	1655
[55]	1656	=head1 ASSUMPTIONS
	1657
	1658	As with rpmbuild, debbuild makes some assumptions about your system.
	1659
	1660	=over 4
	1661
	1662	=item *
	1663
	1664	Either you have rights to do as you please under /usr/src/debian, or you have created a file
	1665	~/.debmacros containing a suitable %_topdir definition.
	1666
[57]	1667	Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
	1668	where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
	1669	requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
[55]	1670	some subdirectories are created automatically as needed, but most are not.
	1671
	1672	=item *
	1673
	1674	/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
	1675	executing shell scripts for much of their functionality. By default, debbuild also creates
	1676	install trees under /var/tmp - however this is (almost) entirely under the control of the
	1677	package's .spec file.
	1678
	1679	=item *
	1680
	1681	If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
	1682	match, or be suitably symlinked one direction or another so that both programs are effectively
	1683	working in the same tree. (Or you could just manually wrestle files around your system.)
	1684
	1685	You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
	1686	if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
	1687	%_topdir macro definition, although there are many more things that rpmbuild can use from
	1688	~/.rpmmacros.
	1689
	1690	=back
	1691
[89]	1692	=head1 ERRATA
	1693
	1694	debbuild deliberately does a few things differently from rpm.
	1695
	1696	=head2 BuildArch or BuildArchitecture
	1697
	1698	rpm takes the last BuildArch entry it finds in the .spec file, whatever it is, and runs with
	1699	that for all packages. Debian's repository system is fairly heavily designed around the
	1700	assumption that a single source package may generate small binary (executable) packages
	1701	for each arch, and large binary arch-all packages containing shared data.
	1702
	1703	debbuild allows this by using the architecture specified by (in order of preference):
	1704
	1705	=over 4
	1706
	1707	=item * Host architecture
	1708
	1709	=item * BuildArch specified in .spec file preamble
	1710
	1711	=item * "Last specified" BuildArch for packages with several subpackages
	1712

	1718
	1719	rpmbuild does not include any convenient method I know of to list the packages a spec file
	1720	will produce. Since I needed this ability for another tool, I added it.
	1721
	1722	It requires the .spec file for the package, and produces a list of full package filenames
	1723	(without path data) that would be generated by one of --rebuild, -ta, -tb, -ba, or -bb.
	1724	This includes the .sdeb source package.

[57]	1728	debbuild was written by Kris Deugau <kdeugau@deepnet.cx>. A version that approximates
	1729	current is available at http://www.deepnet.cx/debbuild/.

	1732
[57]	1733	Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
	1734	fixing this.
[55]	1735
[57]	1736	Many macro expansions are unsupported or incompletely supported.
	1737
	1738	The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
	1739	environment variables and preprocessing that I haven't needed (yet).
	1740
	1741	Dcumentation, such as it is, will likely remain perpetually out of date.
	1742
	1743	%_topdir and the five "working" directories under %_topdir could arguably be created by
	1744	debbuild. However, rpmbuild doesn't create these directories either.
	1745
	1746	=head1 SEE ALSO
	1747
	1748	rpm(8), rpmbuild(8), and pretty much any document describing how to write a .spec file.
