Package: debhelper
Version: 4.9.13
Severity: serious
Justification: causes incorrectly-built packages
While trying to do some debugging involving a GTK-based package, using
libgtk2.0-0-dbg and friends in order to get better backtraces, I noticed that
the better backtraces aren't appearing.
On closer examination, I found that the debug data isn't in /usr/lib/debug,
where it is expected to be, but in /usr/lib/debug/usr/lib. Checking via
packages.d.o shows several other packages with the same and similar problems.
For testing, I picked fontconfig, that being a nice small source package,
from which a -dbg package is built, and tried it... sure enough,
/usr/lib/debug/usr/lib appeared in the -dbg deb. Trying a few commands with a
modified dh_strip (to print out some debug info):
$ ./debian/rules build
...
$ export DH_COMPAT=4
$ dh_clean -k
$ make install DESTDIR=`pwd`/debian/tmp
$ dh_install -plibfontconfig1
$ dh_install -plibfontconfig1-dbg
$ ls -R debian/libfontconfig1-dbg/usr/lib/debug
ls: debian/libfontconfig1-dbg/usr/lib/debug: No such file or directory
$ dh_strip -plibfontconfig1 --dbg-package=libfontconfig1
Debug: file = debian/libfontconfig1/usr/lib/libfontconfig.so.1.0.4
tmp = debian/libfontconfig1
dest = debian/libfontconfig1-dbg
base = /usr/lib/libfontconfig.so.1.0.4
path =
debian/libfontconfig1-dbg/usr/lib/debug//usr/lib/libfontconfig.so.1.0.4
dir = debian/libfontconfig1-dbg/usr/lib/debug//usr/lib
$ ls -R debian/libfontconfig1-dbg/usr/lib/debug
debian/libfontconfig1-dbg/usr/lib/debug:
usr/
debian/libfontconfig1-dbg/usr/lib/debug/usr:
lib/
debian/libfontconfig1-dbg/usr/lib/debug/usr/lib:
libfontconfig.so.1.0.4
(The variables in the debug output are in the order in which they're defined
in make_debug().)
