dh_shlibdeps — calculate shared library dependencies

Synopsis

dh_shlibdeps [debhelper options] [-Lpackage] [-ldirectory] [-Xitem] [-- params]

Description

dh_shlibdeps is a debhelper program that is responsible for calculating shared library dependencies for packages.

This program is merely a wrapper around dpkg-shlibdeps(1) that calls it once for each package listed in the control file, passing it a list of ELF executables and shared libraries it has found.

Options

-Xitem, --exclude=item
Exclude files that contain item anywhere in their filename from being passed to dpkg-shlibdeps. This will make their dependencies be ignored. This may be useful in some situations, but use it with caution. This option may be used more than once to exclude more than one thing.
-- params
Pass params to dpkg-shlibdeps(1).
-uparams, --dpkg-shlibdeps-params=params
This is another way to pass params to dpkg-shlibdeps(1). It is deprecated; use -- instead.
-ldirectory[:directory ...]
With recent versions of dpkg-shlibdeps, this option is generally not needed.

It tells dpkg-shlibdeps (via its -l parameter), to look for private package libraries in the specified directory (or directories -- separate with colons). With recent versions of dpkg-shlibdeps, this is mostly only useful for packages that build multiple flavors of the same library, or other situations where the library is installed into a directory not on the regular library search path.
-Lpackage, --libpackage=package
With recent versions of dpkg-shlibdeps, this option is generally not needed, unless your package builds multiple flavors of the same library.

It tells dpkg-shlibdeps (via its -S parameter) to look first in the package build directory for the specified package, when searching for libraries, symbol files, and shlibs files.

Examples

Suppose that your source package produces libfoo1, libfoo-dev, and libfoo-bin binary packages. libfoo-bin links against libfoo1, and should depend on it. In your rules file, first run dh_makeshlibs, then dh_shlibdeps:

dh_makeshlibs
dh_shlibdeps

This will have the effect of generating automatically a shlibs file for libfoo1, and using that file and the libfoo1 library in the debian/libfoo1/usr/lib directory to calculate shared library dependency information.

If a libbar1 package is also produced, that is an alternate build of libfoo, and is installed into /usr/lib/bar/, you can make libfoo-bin depend on libbar1 as follows:

dh_shlibdeps -Llibbar1 -l/usr/lib/bar
