1340=head1 NAME
1341
1342debbuild - Build Debian-compatible packages from RPM spec files
1343
1344=head1 SYNOPSIS
1345
1346 debbuild {-ba|-bb|-bp|-bc|-bi|-bl|-bs} [build-options] file.spec
1347
1348 debbuild {-ta|-tb|-tp|-tc|-ti|-tl|-ts} [build-options] file.tar.{gz|bz2}
1349
1350 debbuild --rebuild file.{src.rpm|sdeb}
1351
1352 debbuild --showpkgs
1353
1354=head1 DESCRIPTION
1355
1356This script attempts to build Debian-friendly semi-native packages from RPM spec files,
1357RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
1358options rpmbuild does, and should be able to interpret most spec files usefully. Perl
1359modules should be handled via CPAN+dh-make-perl instead; Debian's conventions for such
1360things do not lend themselves to automated conversion.
1361
1362As far as possible, the command-line options are identical to those from rpmbuild, although
1363several rpmbuild options are not supported:
1364
1365 --recompile
1366 --showrc
1367 --buildroot
1368 --clean
1369 --nobuild
1370 --rmsource
1371 --rmspec
1372 --sign
1373 --target
1374
1375Some of these could probably be trivially added. Feel free to send me a patch. ;)
1376
1377Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
1378you'll have to make heavy modifications anyway.
1379
1380If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
1381promise I'll do anything other than say "Yup, that's broken" or "Got your message".
1382
1383=head1 ASSUMPTIONS
1384
1385As with rpmbuild, debbuild makes some assumptions about your system.
1386
1387=over 4
1388
1389=item *
1390
1391Either you have rights to do as you please under /usr/src/debian, or you have created a file
1392~/.debmacros containing a suitable %_topdir definition.
1393
1394Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
1395where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
1396requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
1397some subdirectories are created automatically as needed, but most are not.
1398
1399=item *
1400
1401/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
1402executing shell scripts for much of their functionality. By default, debbuild also creates
1403install trees under /var/tmp - however this is (almost) entirely under the control of the
1404package's .spec file.
1405
1406=item *
1407
1408If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
1409match, or be suitably symlinked one direction or another so that both programs are effectively
1410working in the same tree. (Or you could just manually wrestle files around your system.)
1411
1412You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
1413if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
1414%_topdir macro definition, although there are many more things that rpmbuild can use from
1415~/.rpmmacros.
1416
1417=back
1418
1419=head1 ERRATA
1420
1421debbuild deliberately does a few things differently from rpm.
1422
1423=head2 BuildArch or BuildArchitecture
1424
1425rpm takes the last BuildArch entry it finds in the .spec file, whatever it is, and runs with
1426that for all packages. Debian's repository system is fairly heavily designed around the
1427assumption that a single source package may generate small binary (executable) packages
1428for each arch, and large binary arch-all packages containing shared data.
1429
1430debbuild allows this by using the architecture specified by (in order of preference):
1431
1432=over 4
1433
1434=item * Host architecture
1435
1436=item * BuildArch specified in .spec file preamble
1437
1438=item * "Last specified" BuildArch for packages with several subpackages
1439
1440=item * BuildArch specified in the %package section for that subpackage
1441
1442=back
1443
1444=head2 Finding out what packages should be built (--showpkgs)
1445
1446rpmbuild does not include any convenient method I know of to list the packages a spec file
1447will produce. Since I needed this ability for another tool, I added it.
1448
1449It requires the .spec file for the package, and produces a list of full package filenames
1450(without path data) that would be generated by one of --rebuild, -ta, -tb, -ba, or -bb.
1451This includes the .sdeb source package.
1452
1453=head1 AUTHOR
1454
1455debbuild was written by Kris Deugau <kdeugau@deepnet.cx>. A version that approximates
1456current is available at http://www.deepnet.cx/debbuild/.
1457
1458=head1 BUGS
1459
1460Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
1461fixing this.
1462
1463Many macro expansions are unsupported or incompletely supported.
1464
1465The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
1466environment variables and preprocessing that I haven't needed (yet).
1467
1468Dcumentation, such as it is, will likely remain perpetually out of date.
1469
1470%_topdir and the five "working" directories under %_topdir could arguably be created by
1471debbuild. However, rpmbuild doesn't create these directories either.
