       dh_shlibdeps - calculate shared library dependencies


       dh_shlibdeps [debhelperoptions] [-Lpackage] [-ldirectory] [-Xitem]


       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.


       -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-deb(1).  It is
           deprecated; use -- instead.

           With recent versions of dpkg-shlibdeps, this option is generally
           not needed.

           Before dpkg-shlibdeps is run, LD_LIBRARY_PATH will have added to it
           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

           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.


       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


       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

       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

       This program is a part of debhelper.
