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 will also ensure that ldconfig is invoked during install and removal when it
finds shared libraries. Since debhelper 9.20151004, this is done via a dpkg
trigger. In older versions of debhelper,
dh_makeshlibs would generate a
maintainer script for this purpose.
FILES¶
- debian/package.shlibs
- Installs this file, if present, into the package as DEBIAN/shlibs. If
omitted, debhelper will generate a shlibs file automatically if it detects
any libraries.
Note in compat levels 9 and earlier, this file was installed by
dh_installdeb(1) rather than dh_makeshlibs.
- 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, --no-scripts
- Do not add the "ldconfig" trigger even if it seems like the
package might need it. The option is called --no-scripts for
historical reasons as dh_makeshlibs would previously generate
maintainer scripts that called ldconfig.
- -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)
