NAME¶
dh_makeshlibs - automatically create shlibs file and call dpkg-gensymbols
SYNOPSIS¶
dh_makeshlibs [
debhelper options] [
-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.
Packages that support multiarch are detected, and a Pre-Dependency on
multiarch-support is set in ${misc:Pre-Depends} ; you should make sure to put
that token into an appropriate place in your debian/control file for packages
supporting multiarch.
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 dependency 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)
