Re: [Kea-users] Build warnings under Debian Stretch

[Jason Guy]

Thanks for confirming Francis.

Owen,

I am working with the debian maintainer, and the git repo is basically up
to date, minus the latest patches I sent him today:
https://anonscm.debian.org/cgit/collab-maint/isc-kea.git/
It seems to build fine, and seems to work.

Cheers,
Jason

=> I thought about a change in the legal log/forensic hook to take lease
changes by the lease cmds hook into account. But it did not add a

a tool from the library would be used and at the end it was not so

be reconsidered and if still useless removed... BTW it has no impact

If you point me at your work in progress I can compare it with my Debian 
package of 1.3 :-).

Re: [Kea-users] Build warnings under Debian Stretch

[Klaus Steden]

I've seen "unknown substitution variable ${shlibs:Depends}" many times
building Debian packages but I can't recall that it's ever caused an issue.
I think you're probably okay to ignore that one, it's a message burped by
the packaging process but shouldn't affect the binaries themselves.

cheers,
Klaus

[Kea-users] Build warnings under Debian Stretch

[Jason Guy]

Hi folks. I was working on getting the 1.3 debian package build tested.
There are a few errors in the debian git repo that I need to get fixed, but
I am trying to help the maintainer keep the kea package up to date, and
hopefully stay that way.

In my latest build, I see a few warnings, and I was not sure if these are
something I should file a bug for, or simply ignore under Debian. None of
these cause a problem, but I want to verify these will not be an issue:

dpkg-shlibdeps: warning: package could avoid a useless dependency if
debian/kea-common/usr/lib/x86_64-linux-gnu/libkea-dhcpsrv.so.8.0.0 was not
linked against libz.so.1 (it uses none of the library's symbols)

dpkg-shlibdeps: warning: package could avoid a useless dependency if
debian/kea-common/usr/lib/x86_64-linux-gnu/hooks/libdhcp_lease_cmds.so
debian/kea-common/usr/lib/x86_64-linux-gnu/libkea-dhcp_ddns.so.1.0.2
debian/kea-common/usr/lib/x86_64-linux-gnu/libkea-process.so.1.0.0
debian/kea-common/usr/lib/x86_64-linux-gnu/libkea-dhcpsrv.so.8.0.0 were not
linked against libkea-cfgclient.so.4 (they use none of the library's
symbols)
   dh_installdeb -O-B
   dh_gencontrol -O-B

dpkg-gencontrol: warning: Depends field of package kea-dev: unknown
substitution variable ${shlibs:Depends}
   dh_md5sums -O-B
   dh_builddeb -O-B

This last one is a little strange. I am not entirely why the kea-dev
package would not have any shared library dependencies. This may be a
Debian specific thing... Anyhow, looking for any help/advice on these.

Thanks,
Jason
