1567debbuild - Build Debian-compatible packages from RPM spec files
1568
1569=head1 SYNOPSIS
1570
1571 debbuild {-ba|-bb|-bp|-bc|-bi|-bl|-bs} [build-options] file.spec
1572
1573 debbuild {-ta|-tb|-tp|-tc|-ti|-tl|-ts} [build-options] file.tar.{gz|bz2}
1574
1575 debbuild --rebuild file.{src.rpm|sdeb}
1576
1577 debbuild --showpkgs
1578
1579=head1 DESCRIPTION
1580
1581This script attempts to build Debian-friendly semi-native packages from RPM spec files,
1582RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
1583options rpmbuild does, and should be able to interpret most spec files usefully. Perl
1584modules should be handled via CPAN+dh-make-perl instead; Debian's conventions for such
1585things do not lend themselves to automated conversion.
1586
1587As far as possible, the command-line options are identical to those from rpmbuild, although
1588several rpmbuild options are not supported:
1589
1590 --recompile
1591 --showrc
1592 --buildroot
1593 --clean
1594 --nobuild
1595 --rmsource
1596 --rmspec
1597 --sign
1598 --target
1599
1600Some of these could probably be trivially added. Feel free to send me a patch. ;)
1601
1602Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
1603you'll have to make heavy modifications anyway.
1604
1605If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
1606promise I'll do anything other than say "Yup, that's broken" or "Got your message".
1607
1608=head1 ASSUMPTIONS
1609
1610As with rpmbuild, debbuild makes some assumptions about your system.
1611
1612=over 4
1613
1614=item *
1615
1616Either you have rights to do as you please under /usr/src/debian, or you have created a file
1617~/.debmacros containing a suitable %_topdir definition.
1618
1619Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
1620where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
1621requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
1622some subdirectories are created automatically as needed, but most are not.
1623
1624=item *
1625
1626/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
1627executing shell scripts for much of their functionality. By default, debbuild also creates
1628install trees under /var/tmp - however this is (almost) entirely under the control of the
1629package's .spec file.
1630
1631=item *
1632
1633If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
1634match, or be suitably symlinked one direction or another so that both programs are effectively
1635working in the same tree. (Or you could just manually wrestle files around your system.)
1636
1637You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
1638if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
1639%_topdir macro definition, although there are many more things that rpmbuild can use from
1640~/.rpmmacros.
1641
1642=back
1643
1644=head1 ERRATA
1645
1646debbuild deliberately does a few things differently from rpm.
1647
1648=head2 BuildArch or BuildArchitecture
1649
1650rpm takes the last BuildArch entry it finds in the .spec file, whatever it is, and runs with
1651that for all packages. Debian's repository system is fairly heavily designed around the
1652assumption that a single source package may generate small binary (executable) packages
1653for each arch, and large binary arch-all packages containing shared data.
1654
1655debbuild allows this by using the architecture specified by (in order of preference):
1656
1657=over 4
1658
1659=item * Host architecture
1660
1661=item * BuildArch specified in .spec file preamble
1662
1663=item * "Last specified" BuildArch for packages with several subpackages
1664
1665=item * BuildArch specified in the %package section for that subpackage
1666
1667=back
1668
1669=head2 Finding out what packages should be built (--showpkgs)
1670
1671rpmbuild does not include any convenient method I know of to list the packages a spec file
1672will produce. Since I needed this ability for another tool, I added it.
1673
1674It requires the .spec file for the package, and produces a list of full package filenames
1675(without path data) that would be generated by one of --rebuild, -ta, -tb, -ba, or -bb.
1676This includes the .sdeb source package.

1681current is available at http://www.deepnet.cx/debbuild/.
1682
1683=head1 BUGS
1684
1685Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
1686fixing this.
1687
1688Many macro expansions are unsupported or incompletely supported.
1689
1690The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
1691environment variables and preprocessing that I haven't needed (yet).
1692
1693Dcumentation, such as it is, will likely remain perpetually out of date.
1694
1695%_topdir and the five "working" directories under %_topdir could arguably be created by
1696debbuild. However, rpmbuild doesn't create these directories either.
