3# Shamelessly steals interface from rpm's "rpmbuild" to create
4# Debian packages. Please note that such packages are highly
5# unlikely to conform to "Debian Policy".

393Build options with [ <specfile> | <tarball> | <source package> ]:
394 -bp build through %prep (unpack sources and apply patches) from <specfile>
395 -bc build through %build (%prep, then compile) from <specfile>
396 -bi build through %install (%prep, %build, then install) from <specfile>
397 -bl verify %files section from <specfile>
398 -ba build source and binary packages from <specfile>
399 -bb build binary package only from <specfile>
400 -bs build source package only from <specfile>
401 -tp build through %prep (unpack sources and apply patches) from <tarball>
402 -tc build through %build (%prep, then compile) from <tarball>
403 -ti build through %install (%prep, %build, then install) from <tarball>
404 -ta build source and binary packages from <tarball>
405 -tb build binary package only from <tarball>
406 -ts build source package only from <tarball>
407 --rebuild build binary package from <source package>
408 --buildroot=DIRECTORY override build root
409 --short-circuit skip straight to specified stage (only for c,i)
410

413

1853=head1 NAME
1854
1855debbuild - Build Debian-compatible .deb packages from RPM .spec files
1856
1857=head1 SYNOPSIS
1858
1859 debbuild {-ba|-bb|-bp|-bc|-bi|-bl|-bs} [build-options] file.spec
1860
1861 debbuild {-ta|-tb|-tp|-tc|-ti|-tl|-ts} [build-options] file.tar.{gz|bz2|xz}
1862
1863 debbuild --rebuild file.{src.rpm|sdeb}
1864
1865 debbuild --showpkgs
1866
1867=head1 DESCRIPTION
1868
1869debbuild attempts to build Debian-friendly semi-native packages from RPM spec files,
1870RPM-friendly tarballs, and RPM source packages (.src.rpm files). It accepts I<most> of the
1871options rpmbuild does, and should be able to interpret most spec files usefully. Perl
1872modules should be handled via CPAN+dh-make-perl instead as it's simpler than even tweaking
1873a .spec template.
1874
1875As far as possible, the command-line options are identical to those from rpmbuild, although
1876several rpmbuild options are not supported:
1877
1878 --recompile
1879 --showrc
1880 --buildroot
1881 --clean
1882 --nobuild
1883 --rmsource
1884 --rmspec
1885 --sign
1886 --target
1887
1888Some of these could probably be trivially added. Feel free to send me a patch. ;)
1889
1890Complex spec files will most likely not work well, if at all. Rewrite them from scratch -
1891you'll have to make heavy modifications anyway.
1892
1893If you see something you don't like, mail me. Send a patch if you feel inspired. I don't
1894promise I'll do anything other than say "Yup, that's broken" or "Got your message".
1895
1896=head1 ASSUMPTIONS
1897
1898As with rpmbuild, debbuild makes some assumptions about your system.
1899
1900=over 4
1901
1902=item *
1903
1904Either you have rights to do as you please under /usr/src/debian, or you have created a file
1905~/.debmacros containing a suitable %_topdir definition.
1906
1907Both rpmbuild and debbuild require the directories %_topdir/{BUILD,SOURCES,SPECS}. However,
1908where rpmbuild requires the %_topdir/{RPMS,SRPMS} directories, debbuild
1909requires %_topdir/{DEBS,SDEBS} instead. Create them in advance;
1910some subdirectories are created automatically as needed, but most are not.
1911
1912=item *
1913
1914/var/tmp must allow script execution - rpmbuild and debbuild both rely on creating and
1915executing shell scripts for much of their functionality. By default, debbuild also creates
1916install trees under /var/tmp - however this is (almost) entirely under the control of the
1917package's .spec file.
1918
1919=item *
1920
1921If you wish to --rebuild a .src.rpm, your %_topdir for both debbuild and rpmbuild must either
1922match, or be suitably symlinked one direction or another so that both programs are effectively
1923working in the same tree. (Or you could just manually wrestle files around your system.)
1924
1925You could symlink ~/.rpmmacros to ~/.debmacros (or vice versa) and save yourself some hassle
1926if you need to rebuild .src.rpm packages on a regular basis. Currently debbuild only uses the
1927%_topdir macro definition, although there are many more things that rpmbuild can use from
1928~/.rpmmacros.

1934debbuild deliberately does a few things differently from rpm.
1935
1936=head2 BuildArch or BuildArchitecture
1937
1938rpm takes the last BuildArch entry it finds in the .spec file, whatever it is, and runs with
1939that for all packages. Debian's repository system is fairly heavily designed around the
1940assumption that a single source package may generate small binary (executable) packages
1941for each arch, and large binary arch-all packages containing shared data.
1942
1943debbuild allows this by using the architecture specified by (in order of preference):
1944
1945=over 4
1946
1947=item * Host architecture
1948
1949=item * BuildArch specified in .spec file preamble
1950
1951=item * "Last specified" BuildArch for packages with several subpackages
1952
1953=item * BuildArch specified in the %package section for that subpackage
1954

1956
1957=head2 Finding out what packages should be built (--showpkgs)
1958
1959rpmbuild does not include any convenient method I know of to list the packages a spec file
1960will produce. Since I needed this ability for another tool, I added it.
1961
1962It requires the .spec file for the package, and produces a list of full package filenames
1963(without path data) that would be generated by one of --rebuild, -ta, -tb, -ba, or -bb.
1964This includes the .sdeb source package.

1972
1973Funky Things Happen if you forget a command-line option or two. I've been too lazy to bother
1974fixing this.
1975
1976Many macro expansions are unsupported or incompletely supported.
1977
1978The generated scriptlets don't quite match those from rpmbuild exactly. There are extra
1979environment variables and preprocessing that I haven't needed (yet).
1980
1981Dcumentation, such as it is, will likely remain perpetually out of date.
1982
1983%_topdir and the five "working" directories under %_topdir could arguably be created by
1984debbuild. However, rpmbuild doesn't create these directories either.
