NAME

       dh_makeshlibs - automatically create shlibs file and call dpkg-gensymbols

SYNOPSIS

       dh_makeshlibs [debhelper options] [-mmajor] [-V[dependencies]] [-n] [-Xitem] [-- params]

DESCRIPTION

       dh_makeshlibs is a debhelper program that automatically scans for shared libraries, and generates a
       shlibs file for the libraries it finds.

       It also adds a call to ldconfig in the postinst and postrm scripts (in v3 mode and above only) to any
       packages in which it finds shared libraries.

       Packages that support multiarch are detected, and a Pre-Dependency on multiarch-support is set in
       ${misc:Pre-Depends} ; you should make sure to put that token into an appropriate place in your
       debian/control file for packages supporting multiarch.

FILES

       debian/package.symbols
       debian/package.symbols.arch
           These  symbols files, if present, are passed to dpkg-gensymbols(1) to be processed and installed. Use
           the arch specific names if you need to provide different symbols files for different architectures.

OPTIONS

       -mmajor, --major=major
           Instead of trying to guess the major number of  the  library  with  objdump,  use  the  major  number
           specified  after  the  -m parameter. This is much less useful than it used to be, back in the bad old
           days when this program looked at library filenames rather than using objdump.

       -V, -Vdependencies
       --version-info, --version-info=dependencies
           By default, the shlibs file generated by this program does not make packages depend on any particular
           version of the package containing the shared library. It may be necessary for you to add some version
           dependency information to the shlibs file. If -V is specified with  no  dependency  information,  the
           current upstream version of the package is plugged into a dependency that looks like "packagename (>=
           packageversion)".  Note  that  in  debhelper  compatibility  levels before v4, the Debian part of the
           package version number is also included. If -V is specified with parameters, the  parameters  can  be
           used to specify the exact dependency information needed (be sure to include the package name).

           Beware  of  using  -V without any parameters; this is a conservative setting that always ensures that
           other packages' shared library dependencies are at least as tight as they need  to  be  (unless  your
           library  is  prone  to  changing  ABI  without  updating the upstream version number), so that if the
           maintainer screws up then they won't break. The  flip  side  is  that  packages  might  end  up  with
           dependencies that are too tight and so find it harder to be upgraded.

       -n, --noscripts
           Do not modify postinst/postrm scripts.

       -Xitem, --exclude=item
           Exclude  files that contain item anywhere in their filename or directory from being treated as shared
           libraries.

       --add-udeb=udeb
           Create an additional line for udebs in the shlibs file and use udeb as the package name for udebs  to
           depend on instead of the regular library package.

       -- params
           Pass params to dpkg-gensymbols(1).

EXAMPLES

       dh_makeshlibs
           Assuming this is a package named libfoobar1, generates a shlibs file that looks something like:
            libfoobar 1 libfoobar1

       dh_makeshlibs -V
           Assuming  the  current  version of the package is 1.1-3, generates a shlibs file that looks something
           like:
            libfoobar 1 libfoobar1 (>= 1.1)

       dh_makeshlibs -V 'libfoobar1 (>= 1.0)'
           Generates a shlibs file that looks something like:
             libfoobar 1 libfoobar1 (>= 1.0)
