[Pkg-xfce-devel] Bug#890223: libgarcon-common and libgarcon-1-0-dev cannot satify dependencies from foreign architectures

[Helmut Grohne]

Package: libgarcon-common,libgarcon-1-0-dev
Version: 0.6.1-2
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap
Control: affects -1 + src:vala-panel-appmenu src:xfce4-cpufreq-plugin src:xfce4-cpugraph-plugin src:xfce4-equake-plugin src:xfce4-hdaps src:xfce4-messenger-plugin src:xfce4-panel src:xfce4-places-plugin src:xfce4-power-manager src:xfce4-settings src:xfce4-whiskermenu-plugin src:xfce4-wmdock-plugin src:xfce4-xkb-plugin src:xfdesktop4 src:xfswitch-plugin

The affected packages cannot satify their cross Build-Depends. Each of
them has a transitive dependency reaching out to libgarcon-common or
libgarcon-1-0-dev. Both of these packages are Architecture: all and thus
can never satisfy cross Build-Depends unless marked Multi-Arch: foreign.

For libgarcon-common that marking is correct as it lacks maintainer
scripts and dependencies, but for libgarcon-1-0-dev that marking would
be fatal: It would pull the build architecture libgarcon-1-dev and cross
builds would be unable to find the library for the host architecture.
Thus libgarcon-1-0-dev must be switched to Architecture: any.

Rule of thumb: Transitional packages should copy the Architecture field
of their target dependency.

The attached patch implements both changes and additionally marks all
packages Multi-Arch: same (as that happens to be correct and might help
lateron). Please consider applying it.
