Programs which embed a perl interpreter must declare a
Build-Depends on libperl-dev.
The default linker options produced by
perl -MExtUtils::Embed -e ldopts
will link against the dynamic libperl. If
programs wish to link to the static library, then
-lperl should be changed to
/usr/lib/libperl.a in those options.
Dependencies for programs linking against the shared Perl library
will be automatically created by
dpkg-shlibdeps. Note however that the shared
perl library package only suggests perl-base and packages requiring any
core modules from the perl package must depend upon it
explicitly.
Starting from perl
5.12.3-2, a dpkg trigger named
perl-major-upgrade will be triggered by
the postinst of the perl
package during major upgrades. Some examples of things which
constitute a major upgrade are an upgrade which would change the
value of versioned directories in @INC, or one
which changes abiname. Any package may declare
an interest in the trigger, especially packages including
long-running daemons which would stop working until restart.
It is suggested that such packages include an appropriate section in their postinst to handle the trigger by restarting relevant daemons or notifying users of further action.
