NAME

       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 or is relying on
           debian/shlibs.local for an internal 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.

           If needed, this can be passed multiple times with different package names.

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
