Multi-Arch and debian/control

["Thomas Schmitt" <scdbackup@gmx.net>]

Hi,

while preparing the correction for a buildd failure on Debian
GNU/kFreeBSD i got a lintian complaint from kfreebsd-i386 7.9
(the current "stable"):

    E: libburn4: missing-pre-dependency-on-multiarch-support

I found
  https://wiki.debian.org/Multiarch/Implementation#dh.281.29_and_autotools
This page seems to be recent, as it talks of "debhelper (>= 9)".

It prescribes to add to multi-arch dynamic library packages

  Pre-Depends: ${misc:Pre-Depends}
  Multi-Arch: same

Is this still a valid prescription ?
(Why then is amd64 Sid lintian silent about it ?)

--------------------------------------------------------------

I came to debian-policy, "8.2 Shared library support files":

  "If your package contains files whose names do not change with
   each change in the library shared object version, you must not
   put them in the shared library package."

But inherited from my many predecessors i have some doc stuff
in the runtime library package:

  $ apt-file list libburn4
  libburn4: /usr/lib/x86_64-linux-gnu/libburn.so.4
  libburn4: /usr/lib/x86_64-linux-gnu/libburn.so.4.93.0
  libburn4: /usr/share/doc/libburn4/AUTHORS
  libburn4: /usr/share/doc/libburn4/NEWS.gz
  libburn4: /usr/share/doc/libburn4/README.gz
  libburn4: /usr/share/doc/libburn4/changelog.Debian.gz
  libburn4: /usr/share/doc/libburn4/changelog.gz
  libburn4: /usr/share/doc/libburn4/copyright

Do i have to remove the /usr/share/doc files from libburn4 ?

(Actually the prescription says that i'd even have to remove
 libburn.so.4, as it says "names" and not "content".
 Somehow not very realistic.)

-----------------------------------------------------------------

What to do with the other packages from libburn ?

The Multiarch page prescribes to add the Pre-Depends line
to each package which provides a shared library.

libburn-dbg seems to modify libburn.so.4.X.0 .
libburn-dev installs a link libburn.so to libburn.so.4.X.0 .

Do they need multi-arch headers in debian/control ?

Have a nice day :)
