DH_STRIP(1)                       Debhelper                      DH_STRIP(1)

NAME         top

       dh_strip - strip executables, shared libraries, and some static
       libraries

SYNOPSIS         top

       dh_strip [debhelper options] [-Xitem] [--dbg-package=package]
       [--keep-debug]

DESCRIPTION         top

       dh_strip is a debhelper program that is responsible for stripping
       executables, shared libraries, and static libraries that are not used
       for debugging.

       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.

OPTIONS         top

       -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.

       --dbg-package=package
           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 automatically
           generates debug packages ("dbgsym packages").  If you have a
           manual --dbg-package that you want to replace with an
           automatically generated debug symbol package, please see the
           --dbgsym-migration option.

           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 package.

           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.

           This option implies --no-automatic-dbgsym and cannot be used with
           --automatic-dbgsym or --dbgsym-migration.

       -k, --keep-debug
           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 automatically
           generates debug packages ("dbgsym packages").  If you have a
           manual --dbg-package that you want to replace with an
           automatically generated debug symbol package, please see the
           --dbgsym-migration option.

           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-automatic-dbgsym and cannot be used with
           --automatic-dbgsym.

       --dbgsym-migration=package-relation
           This option is used to migrate from a manual "-dbg" package
           (created with --dbg-package) to an automatic generated debug
           symbol package. This option should describe a valid Replaces- and
           Breaks-relation, which will be added to the debug symbol package
           to avoid file conflicts with the (now obsolete) -dbg package.

           This option implies --automatic-dbgsym and cannot be used with
           --keep-debug, --dbg-package or --no-automatic-dbgsym.

           Examples:

             dh_strip --dbgsym-migration='libfoo-dbg (<< 2.1-3~)'

             dh_strip --dbgsym-migration='libfoo-tools-dbg (<< 2.1-3~), libfoo2-dbg (<< 2.1-3~)'

       --automatic-dbgsym, --no-automatic-dbgsym
           Control whether dh_strip should be creating debug symbol packages
           when possible.

           The default is to create debug symbol packages.

       --ddebs, --no-ddebs
           Historical name for --automatic-dbgsym and --no-automatic-dbgsym.

       --ddeb-migration=package-relation
           Historical name for --dbgsym-migration.

NOTES         top

       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 automatic creation of
       debug symbol packages.

       The automatic creation of debug symbol packages can also be prevented
       by adding noautodbgsym to the DEB_BUILD_OPTIONS environment variable.
       However, dh_strip will still add debuglinks to ELF binaries when this
       flag is set.  This is to ensure that the regular deb package will be
       identical with and without this flag (assuming it is otherwise "bit-
       for-bit" reproducible).
