NAME

dh_makeshlibs - automatically create shlibs file and call
dpkg-gensymbols

SYNOPSIS

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

DESCRIPTION

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.

FILES

debian/package.symbols
debian/package.symbols.arch

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.

OPTIONS

-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
upgraded.

-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.

--add-udeb=udeb

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).

EXAMPLES

dh_makeshlibs

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)
