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 which it finds shared libraries in.
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 (>= packageversion)''. If -V is
specified with parameters, the parameters can be used to specify the exact
dependancy 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, 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.
Exclude files that contain ``item'' anywhere in their filename from
being treated as shared libraries.
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 (>= 1.0-3)
dh_makeshlibs -V 'libfoobar1 (>= 1.0)'
Generates a shlibs file that looks something like:
libfoobar 1 libfoobar1 (>= 1.0)
