       dh_makeshlibs - automatically create shlibs file and call


       dh_makeshlibs [debhelperoptions] [-mmajor] [-V[dependencies]] [-n]
       [-Xitem] [--params]


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

       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


           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


       -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
           dependancy 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

       -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.

           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).


           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)



       This program is a part of debhelper.
