dh_perl
DH_PERL(1) Debhelper DH_PERL(1)NAME
dh_perl - calculates Perl dependencies and cleans up after MakeMaker
SYNOPSIS
dh_perl [debhelperoptions] [-d] [librarydirs...]
DESCRIPTION
dh_perl is a debhelper program that is responsible for generating the ${perl:Depends} substitutions and adding them to substvars files.
The program will look at Perl scripts and modules in your package, and will use this information to generate a dependency on perl or
perlapi. The dependency will be substituted into your package's control file wherever you place the token ${perl:Depends}.
dh_perl also cleans up empty directories that MakeMaker can generate when installing Perl modules.
OPTIONS -d In some specific cases you may want to depend on perl-base rather than the full perl package. If so, you can pass the -d option to make
dh_perl generate a dependency on the correct base package. This is only necessary for some packages that are included in the base
system.
Note that this flag may cause no dependency on perl-base to be generated at all. perl-base is Essential, so its dependency can be left
out, unless a versioned dependency is needed.
-V By default, scripts and architecture independent modules don't depend on any specific version of perl. The -V option causes the current
version of the perl (or perl-base with -d) package to be specified.
library dirs
If your package installs Perl modules in non-standard directories, you can make dh_perl check those directories by passing their names
on the command line. It will only check the vendorlib and vendorarch directories by default.
CONFORMS TO
Debian policy, version 3.8.3
Perl policy, version 1.20
SEE ALSO debhelper(7)
This program is a part of debhelper.
