1552debbuild - Build Debian-compatible packages from RPM spec files
1553
1554=head1 SYNOPSIS
1555
1556 debbuild {-ba|-bb|-bp|-bc|-bi|-bl|-bs} [build-options] file.spec
1557
1558 debbuild {-ta|-tb|-tp|-tc|-ti|-tl|-ts} [build-options] file.tar.{gz|bz2}
1559
1560 debbuild --rebuild file.{src.rpm|sdeb}
1561
1562 debbuild --showpkgs
1563
1564=head1 DESCRIPTION
1565
1566This script attempts to build Debian-friendly semi-native packages from RPM spec files,
1567RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
1568options rpmbuild does, and should be able to interpret most spec files usefully. Perl
1569modules should be handled via CPAN+dh-make-perl instead; Debian's conventions for such
1570things do not lend themselves to automated conversion.
1571
1572As far as possible, the command-line options are identical to those from rpmbuild, although
1573several rpmbuild options are not supported:
1574
1575 --recompile
1576 --showrc
1577 --buildroot
1578 --clean
1579 --nobuild
1580 --rmsource
1581 --rmspec
1582 --sign
1583 --target
1584
1585Some of these could probably be trivially added. Feel free to send me a patch. ;)
1586
1587Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
1588you'll have to make heavy modifications anyway.
1589
1590If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
1591promise I'll do anything other than say "Yup, that's broken" or "Got your message".
1592
1593=head1 ASSUMPTIONS
1594
1595As with rpmbuild, debbuild makes some assumptions about your system.
1596
1597=over 4
1598
1599=item *
1600
1601Either you have rights to do as you please under /usr/src/debian, or you have created a file
1602~/.debmacros containing a suitable %_topdir definition.
1603
1604Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
1605where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
1606requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
1607some subdirectories are created automatically as needed, but most are not.
1608
1609=item *
1610
1611/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
1612executing shell scripts for much of their functionality. By default, debbuild also creates
1613install trees under /var/tmp - however this is (almost) entirely under the control of the
1614package's .spec file.
1615
1616=item *
1617
1618If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
1619match, or be suitably symlinked one direction or another so that both programs are effectively
1620working in the same tree. (Or you could just manually wrestle files around your system.)
1621
1622You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
1623if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
1624%_topdir macro definition, although there are many more things that rpmbuild can use from
1625~/.rpmmacros.
1626
1627=back
1628
1629=head1 ERRATA
1630
1631debbuild deliberately does a few things differently from rpm.
1632
1633=head2 BuildArch or BuildArchitecture
1634
1635rpm takes the last BuildArch entry it finds in the .spec file, whatever it is, and runs with
1636that for all packages. Debian's repository system is fairly heavily designed around the
1637assumption that a single source package may generate small binary (executable) packages
1638for each arch, and large binary arch-all packages containing shared data.
1639
1640debbuild allows this by using the architecture specified by (in order of preference):
1641
1642=over 4
1643
1644=item * Host architecture
1645
1646=item * BuildArch specified in .spec file preamble
1647
1648=item * "Last specified" BuildArch for packages with several subpackages
1649
1650=item * BuildArch specified in the %package section for that subpackage
1651
1652=back
1653
1654=head2 Finding out what packages should be built (--showpkgs)
1655
1656rpmbuild does not include any convenient method I know of to list the packages a spec file
1657will produce. Since I needed this ability for another tool, I added it.
1658
1659It requires the .spec file for the package, and produces a list of full package filenames
1660(without path data) that would be generated by one of --rebuild, -ta, -tb, -ba, or -bb.
1661This includes the .sdeb source package.

1663=head1 AUTHOR
1664
1665debbuild was written by Kris Deugau <kdeugau@deepnet.cx>. A version that approximates
1666current is available at http://www.deepnet.cx/debbuild/.
1667
1668=head1 BUGS
1669
1670Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
1671fixing this.
1672
1673Many macro expansions are unsupported or incompletely supported.
1674
1675The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
1676environment variables and preprocessing that I haven't needed (yet).
1677
1678Dcumentation, such as it is, will likely remain perpetually out of date.
1679
1680%_topdir and the five "working" directories under %_topdir could arguably be created by
1681debbuild. However, rpmbuild doesn't create these directories either.
