[Ekiga-devel-list] ekiga-snapshot Debian package (was Re: ekiga-snapshot crashes (Debian package 20070827-02-sid.1))

Ciao Kilian!

Sorry, long post, I dug a bit into the different Debian packages, HTH!

First of all, I started to investigate because on a clean and
up-to-date sid (created as described at [1]) ekiga-snapshot doesn't
depend on libopal-cvs and indeed:
root gismo:/# apt-get install libpt-cvs-plugins-v4l2 ekiga-snapshot
The following NEW packages will be installed:
  ekiga-snapshot libpt-cvs libpt-cvs-plugins-alsa libpt-cvs-plugins-v4l2
Setting up libpt-cvs (20070826-03-sid.1) ...
Setting up libpt-cvs-plugins-alsa (20070826-03-sid.1) ...
Setting up libpt-cvs-plugins-v4l2 (20070826-03-sid.1) ...
Setting up ekiga-snapshot (20070828-02-sid.1) ...

root gismo:/# su luca
luca gismo:/$ ekiga-snapshot
ekiga-snapshot: error while loading shared libraries: libopal.so.2.3: \
 cannot open shared object file: No such file or directory
luca gismo:/$root gismo:/#

What's strange is the following:
luca gismo:~$ dpkg-shlibdeps /usr/bin/ekiga-snapshot
dpkg-shlibdeps: warning: could not find any packages for libopal.so.2.3
dpkg-shlibdeps: warning: unable to find dependency information for \
 shared library libopal (soname 2.3, path libopal.so.2.3, dependency \
 field Depends)
dpkg-shlibdeps: failure: open new substvars file \
 debian/substvars.new': No such file or directory
luca gismo:~$

root gismo:/# apt-get install libopal-cvs
The following NEW packages will be installed:
  libgsm1 libopal-cvs libx264-54
Setting up libgsm1 (1.0.10-13) ...
Setting up libx264-54 (0.svn20070309-5~sid.863) ...
Setting up libopal-cvs (20070827-02-sid.1) ...

root gismo:/#

Then, ekiga-snapshot crashes, but I already reported it at [2].

It seems that libavcodec is needed to build libopal-cvs, but strangely
enough libopal-cvs doesn't depend on it (as you can check from the
Packages.gz file at [3]).  Indeed, ldd and dpkg-shlibdeps don't show
any link to libavcodec for the libopal-cvs libraries [4].  I'd say
that libopal-cvs is definitively broken.

FWIW, at least on amd64, libopal-cvs_20070827-02-sid.1 builds
correctly without packages from the debian-multimedia.org repository,
thus I'd remove the X-APT- lines from debian/control ;-)

Officially, it's missing lixb264, which has patent problems [5] :-(

Stopping here for this evening...

Thx, bye,
