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
