Indeed, that is the problem.

To recap on that patch:

Clint's objection was that running find could be rather expensive.

Well, it would make fakeroot depend on dpkg-dev which is rather
undesirable.
I think the solution is for each libfakeroot:$ARCH to add its directory
to fakeroot's search path via a configuration file. Actually, those
already exist, namely the /etc/ld.so.conf.d/fakeroot-*.conf files. So
how about the patch below?

Subject: [PATCH] Make fakeroot multi-arch aware
Each libfakeroot:$ARCH package already adds an entry to
/etc/ld.so.conf.d/, reuse that for fakeroot's own search path.
Remove the lib{64,32}/fakeroot directories from the search path, since
those do not exist anymore.

I have left the directory for the native architecture at the front which
causes a duplicate entry. That should be harmless, but if it is
considered undesirable, it would also be possible to drop @libdir@: from
$PATHS. In that case fakeroot could even become an arch:all package.
Cheers,
Sven

Hi, I attached a tarball of my ./debian directory which converts the package to multiarch but still uses debhelper. I didnt come to converting this to not require debhelper yet but thought it would make sense to document my current status anyway. cheers, josch debian.tar.gz Description: Binary data
Bug#636192: make fakeroot multiarch
Package: fakeroot Version: 1.16-1 Severity: wishlist Hi, when using fakeroot (and fakechroot) to execute foreign binaries with qemu user mode emulation, a foreign libfakeroot-sysv.so is required as well. multiarch would be an easy way to install such a foreign shared library, given that additionally to the original fakeroot package (containing the /usr/bin scripts and manpages and by that being Architecture: all) a libfakeroot package is created (containing the shared library only and marked as Multi-Arch: same) making fakeroot multiarch would also remove all of the mess that is currently going on in debian/rules which does lib32 and lib64 builds. I can prepare a patch for you that converts fakeroot to multiarch if you like/want me to and dont have time? making fakeroot multiarch would also solve #624724 cheers, josch -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
