1602=head1 NAME
1603
1604debbuild - Build Debian-compatible packages from RPM spec files
1605
1606=head1 SYNOPSIS
1607
1608 debbuild {-ba|-bb|-bp|-bc|-bi|-bl|-bs} [build-options] file.spec
1609
1610 debbuild {-ta|-tb|-tp|-tc|-ti|-tl|-ts} [build-options] file.tar.{gz|bz2}
1611
1612 debbuild --rebuild file.{src.rpm|sdeb}
1613
1614 debbuild --showpkgs
1615
1616=head1 DESCRIPTION
1617
1618This script attempts to build Debian-friendly semi-native packages from RPM spec files,
1619RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
1620options rpmbuild does, and should be able to interpret most spec files usefully. Perl
1621modules should be handled via CPAN+dh-make-perl instead; Debian's conventions for such
1622things do not lend themselves to automated conversion.
1623
1624As far as possible, the command-line options are identical to those from rpmbuild, although
1625several rpmbuild options are not supported:
1626
1627 --recompile
1628 --showrc
1629 --buildroot
1630 --clean
1631 --nobuild
1632 --rmsource
1633 --rmspec
1634 --sign
1635 --target
1636
1637Some of these could probably be trivially added. Feel free to send me a patch. ;)
1638
1639Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
1640you'll have to make heavy modifications anyway.
1641
1642If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
1643promise I'll do anything other than say "Yup, that's broken" or "Got your message".
1644
1645=head1 ASSUMPTIONS
1646
1647As with rpmbuild, debbuild makes some assumptions about your system.
1648
1649=over 4
1650
1651=item *
1652
1653Either you have rights to do as you please under /usr/src/debian, or you have created a file
1654~/.debmacros containing a suitable %_topdir definition.
1655
1656Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
1657where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
1658requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
1659some subdirectories are created automatically as needed, but most are not.
1660
1661=item *
1662
1663/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
1664executing shell scripts for much of their functionality. By default, debbuild also creates
1665install trees under /var/tmp - however this is (almost) entirely under the control of the
1666package's .spec file.
1667
1668=item *
1669
1670If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
1671match, or be suitably symlinked one direction or another so that both programs are effectively
1672working in the same tree. (Or you could just manually wrestle files around your system.)
1673
1674You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
1675if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
1676%_topdir macro definition, although there are many more things that rpmbuild can use from
1677~/.rpmmacros.
1678
1679=back
1680
1681=head1 ERRATA
1682
1683debbuild deliberately does a few things differently from rpm.
1684
1685=head2 BuildArch or BuildArchitecture
1686
1687rpm takes the last BuildArch entry it finds in the .spec file, whatever it is, and runs with
1688that for all packages. Debian's repository system is fairly heavily designed around the
1689assumption that a single source package may generate small binary (executable) packages
1690for each arch, and large binary arch-all packages containing shared data.
1691
1692debbuild allows this by using the architecture specified by (in order of preference):
1693
1694=over 4
1695
1696=item * Host architecture
1697
1698=item * BuildArch specified in .spec file preamble
1699
1700=item * "Last specified" BuildArch for packages with several subpackages
1701
1702=item * BuildArch specified in the %package section for that subpackage
1703
1704=back
1705
1706=head2 Finding out what packages should be built (--showpkgs)
1707
1708rpmbuild does not include any convenient method I know of to list the packages a spec file
1709will produce. Since I needed this ability for another tool, I added it.
1710
1711It requires the .spec file for the package, and produces a list of full package filenames
1712(without path data) that would be generated by one of --rebuild, -ta, -tb, -ba, or -bb.
1713This includes the .sdeb source package.
1714
1715=head1 AUTHOR

1717debbuild was written by Kris Deugau <kdeugau@deepnet.cx>. A version that approximates
1718current is available at http://www.deepnet.cx/debbuild/.
1719
1720=head1 BUGS
1721
1722Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
1723fixing this.
1724
1725Many macro expansions are unsupported or incompletely supported.
1726
1727The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
1728environment variables and preprocessing that I haven't needed (yet).
1729
1730Dcumentation, such as it is, will likely remain perpetually out of date.
1731
1732%_topdir and the five "working" directories under %_topdir could arguably be created by
1733debbuild. However, rpmbuild doesn't create these directories either.
