dh_makeshlibs − automatically create shlibs file and call dpkg−gensymbols

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.
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.
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.
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
