       [-Xitem] [-- params]

DESCRIPTION         top

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

       It will also ensure that ldconfig is invoked during install and
       removal when it finds shared libraries.  Since debhelper 9.20151004,
       this is done via a dpkg trigger.  In older versions of debhelper,
       dh_makeshlibs would generate a maintainer script for this purpose.

FILES         top

           Installs this file, if present, into the package as
           DEBIAN/shlibs.  If omitted, debhelper will generate a shlibs file
           automatically if it detects any libraries.

           Note in compat levels 9 and earlier, this file was installed by
           dh_installdeb(1) rather than dh_makeshlibs.

           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

OPTIONS         top

       -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

           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, --no-scripts
           Do not add the "ldconfig" trigger even if it seems like the
           package might need it.  The option is called --no-scripts for
           historical reasons as dh_makeshlibs would previously generate
           maintainer scripts that called ldconfig.

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

           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         top

           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)
