dh_makeshlibs - automatically create shlibs file and call dpkg-gensymbols
dh_makeshlibs [debhelper options] [-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 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.
If a dpkg-gensymbols(1) symbol file is found in debian/package.symbols (or debian/package.symbols.arch), dpkg-gensymbols will be called to process and install the symbols file.
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 upgraded.
This program is a part of debhelper.
