dh_makeshlibs is a debhelper program that automatically scans for shared libraries, and generates a shlibs file for the libraries it finds.
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 dependancy information, the current version of the package is plugged into a dependancy that looks like ``packagename (
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, 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.
Do not modify postinst/postrm scripts.
Assuming this is a package named libfoobar1, generates a shlibs file that looks something like: libfoobar 1 libfoobar1
Assuming the current version of the package is 1.0-3, generates a shlibs file that looks something like: libfoobar 1 libfoobar1 (
