dh_strip - strip executables, shared libraries, and some static libraries
dh_strip [debhelper options] [-Xitem] [--dbg-package=package] [--keep-debug]
dh_strip is a debhelper program that is responsible for stripping
executables, shared libraries, and static libraries that are not used for
This program examines your package build directories and works out what
to strip on its own. It uses file(1) and file permissions and filenames
to figure out what files are shared libraries (*.so), executable binaries,
and static (lib*.a) and debugging libraries (lib*_g.a, debug/*.so), and
strips each as much as is possible. (Which is not at all for debugging
libraries.) In general it seems to make very good guesses, and will do the
right thing in almost all cases.
Since it is very hard to automatically guess if a file is a
module, and hard to determine how to strip a module, dh_strip does not
currently deal with stripping binary modules such as .o files.
- -Xitem, --exclude=item
Exclude files that contain item anywhere in their filename from being
stripped. You may use this option multiple times to build up a list of
things to exclude.
This option is a now special purpose option that you normally do not
need. In most cases, there should be little reason to use this
option for new source packages as debhelper generates automatic debug
packages (``ddebs''). If you have a manual --dbg-package that you
want to migrate to the automatic ddeb, please see the
Causes dh_strip to save debug symbols stripped from the packages it acts on
as independent files in the package build directory of the specified debugging
For example, if your packages are libfoo and foo and you want to include a
foo-dbg package with debugging symbols, use dh_strip --dbg-package=foo-dbg.
Note that this option behaves significantly different in debhelper
compatibility levels 4 and below. Instead of specifying the name of a debug
package to put symbols in, it specifies a package (or packages) which
should have separated debug symbols, and the separated symbols are placed
in packages with -dbg added to their name.
This option implies --no-ddebs and cannot be used with --ddeb
- -k, --keep-debug
Debug symbols will be retained, but split into an independent
file in usr/lib/debug/ in the package build directory. --dbg-package
is easier to use than this option, but this option is more flexible.
This option implies --no-ddebs and cannot be used with
This option is used to migrate from a manual ``-dbg'' package (created
with --dbg-package) to the automatic ``ddebs''. The value of this
option should describe a valid Replaces- and Breaks-relation,
which will be added to the ddebs to avoid file conflicts with the (now
obsolete) -dbg package.
This option implies --ddebs and cannot be used with
--keep-debug, --dbg-package or --no-ddebs.
dh_strip --ddeb-migration='libfoo-dbg (<< 2.1-3~)'
dh_strip --ddeb-migration='libfoo-tools-dbg (<< 2.1-3~), libfoo2-dbg (<< 2.1-3~)'
- --ddebs, --no-ddebs
Control whether dh_strip should be creating ddebs when possible.
By default, dh_strip will attempt to build ddebs and this option is
primarily useful for disabling this.
If the DEB_BUILD_OPTIONS environment variable contains nostrip, nothing
will be stripped, in accordance with Debian policy (section 10.1
``Binaries''). This will also inhibit the creation of automatic ``ddebs''.
The creation of automatic ``ddebs'' can also be prevented by adding
noddebs to the DEB_BUILD_OPTIONS environment variable.
