Bug#538593: libxvmc: FTBFS with new source format 3.0 (quilt): incompatible patch management rules
Package: libxvmc
Version: 1:1.0.4-2
Severity: wishlist
Usertags: 3.0-quilt-by-default
To prepare a possible switch to the new source package format "3.0
(quilt)" [1], I converted all source packages and rebuilt the packages
afterwards to see what breaks, and libxvmc does break. To reproduce the
problem you can do this:
$ apt-get source libxvmc
$ mkdir -p libxvmc-1.0.4/debian/source
$ echo "3.0 (quilt)" >libxvmc-1.0.4/debian/source/format
$ dpkg-source -b libxvmc-1.0.4
$ dpkg-source -x libxvmc_1.0.4-2.dsc
$ cd libxvmc-1.0.4 && debuild -us -uc
In this process, if the .diff.gz contains changes to upstream files,
dpkg-source will have created a corresponding patch in
debian/patches/debian-changes-1:1.0.4-2 and will have registered that
patch in a quilt series (debian/patches/series, it is created if needed).
All the patches listed in the "series" file are applied directly during
the extraction (dpkg-source -x). quilt itself is used if available (and
will thus lead to the creation of the .pc directory), otherwise
dpkg-source applies the patches by itself. For more information about the
new source package format see the manual page dpkg-source(1).
In the case of libxvmc, the custom patch application code is
incompatible with direct quilt usage. It fails trying to remove
the expected .pc symlink because it's a real directory created during
source extraction.
Consider switching to xsfbs which has been updated to be compatible
already (see discussion starting at
http://lists.debian.org/debian-x/2008/05/msg01250.html).
