dh_strip is a debhelper program that is responsible for stripping out
debug symbols in executables, shared libraries, and static libraries that are
not needed during execution.
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.
-
--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.
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).
