 debbuild {--install|-i} foo.sdeb


debbuild attempts to build Debian-friendly semi-native packages from RPM spec files, RPM-friendly tarballs, and RPM source packages (.src.rpm files).  It accepts most of the options rpmbuild does, and should be able to interpret most spec files usefully.  Perl modules should be handled via CPAN+dh-make-perl instead as it’s simpler than even tweaking a .spec template.

As far as possible, the command-line options are identical to those from rpmbuild, although several rpmbuild options are not supported:


Some of these could probably be trivially added.  Feel free to send me a patch.  ;)

Complex spec files will most likely not work well, if at all.  Rewrite them from scratch – you’ll have to make heavy modifications anyway.

If you see something you don’t like, mail me.  Send a patch if you feel inspired.  I don’t promise I’ll do anything other than say “Yup, that’s broken” or “Got your message”.

The source package container I invented for debbuild, the .sdeb file, can be installed with debbuild -i exactly the same way as a .src.rpm can be installed with rpm -i.  Both will unpack the file and place the source(s) and .spec file in the appropriate places in %_topdir/SOURCES and %_topdir/SPECS respectively.


As with rpmbuild, debbuild makes some assumptions about your system.


debbuild deliberately does a few things differently from rpmbuild.

Finding out what packages should be built (--showpkgs)

rpmbuild does not include any convenient method I know of to list the packages a spec file will produce.  Since I needed this ability for another tool, I added it.

It requires the .spec file for the package, and produces a list of full package filenames (without path data) that would be generated by one of --rebuild, -ta, -tb, -ra, -rb, -ba, or -bb.  This includes the .sdeb source package.


debbuild was written by Kris Deugau <>.  The present version was developed by Andreas Scherer <> and is available at <>.


Funky Things Happen if you forget a command-line option or two.  I’ve been too lazy to bother fixing this.

Many macro expansions are supported, some are incompletely supported, some not at all.

The generated scriptlets don’t quite match those from rpmbuild exactly.  There are extra environment variables and preprocessing that I haven't needed (yet).

Documentation, such as it is, will likely remain perpetually out of date (in which way it follows in RPM’s tradition).

%_topdir and the five “working” directories under %_topdir could arguably be created by debbuild.  However, rpmbuild doesn't create these directories either.
