Package: sbuild
Version: 0.60.8-1
Severity: wishlist
Hello,
I would love sbuild to gain the ability to handle cross builds. What is a
cross build? Well, it is a way to generate a binary which it is meant to run on
a foreign architecture. For cross builds you need cross tools, which are not
yet in Debian archive, but those are available via emdebian.org repositories.
So basically, you need to add
deb http://emdebian.org squeeze main
into your sources.list, update and install, for example,
linux-libc-dev-armel-cross, libc6-dev-armel-cross, gcc-4.3-arm-linux-gnueabi, ..
Once you got the cross toolchain in place, you can try to cross compile hello
application passing -a$arch option to dpkg-buildpackage and the package must
support cross building, usually by adding a three liner [0] to the package
build system file.
(sid_amd64)zumbi@cat:/tmp/hello-2.6$ dpkg-buildpackage -us -uc -rfakeroot
-aarmel
[...]
chown -R root:root debian/tmp
chmod -R u+w,go=rX debian/tmp
dpkg --build debian/tmp ..
dpkg-deb: building package `hello' in `../hello_2.6-1_armel.deb'.
dpkg-genchanges >../hello_2.6-1_armel.changes
dpkg-genchanges: including full source code in upload
dpkg-source --after-build hello-2.6
dpkg-buildpackage: full upload (original source is included)
When trying sbuild to do it for me,
$ sudo sbuild -d sid_amd64 --debbuildopt="-aarmel" hello_2.6-1
[...]
chmod -R u+w,go=rX debian/tmp
dpkg --build debian/tmp ..
dpkg-deb: building package `hello' in `../hello_2.6-1_armel.deb'.
dpkg-genchanges -B >../hello_2.6-1_armel.changes
dpkg-genchanges: arch-specific upload - not including arch-independent packages
dpkg-genchanges: binary-only upload - not including any source code
dpkg-source --after-build hello-2.6
dpkg-buildpackage: binary only upload (no source included)

Build needed 00:00:12, 4812k disc space
Sbuild builds the package but it is unable to take it out of the chroot,
because it is unable to find the right changes file for the right architecture.
"Can't find hello_2.6-1_amd64.changes -- can't dump info"
Doing a $nasty hack on Build.pm we are able to follow *_armel.changes file.
$ sudo vi /usr/share/perl5/Sbuild/Build.pm +1944
# Figure out chroot architecture
sub chroot_arch {
my $self = shift;
my $nasty = "armel";
^^^^^
my $pipe = $self->get('Session')->pipe_command(
{ COMMAND => [$self->get_conf('DPKG'),
'--print-architecture'],
USER => $self->get_conf('USERNAME'),
CHROOT => 1,
PRIORITY => 0,
DIR => '/' }) || return undef;
chomp(my $chroot_arch = <$pipe>);
close($pipe);
die "Can't determine architecture of chroot: $!\n"
if ($? || !defined($chroot_arch));
return $nasty;
^^^^^
# return $chroot_arch;
}
It seems that sbuild triggers dpkg --print-architecture to find out chroot
architecture, but when doing cross it should try to follow dpkg-architecture's
DEB_HOST_ARCH.
Would it be possible to modify Build.pm in some way, either calling
dpkg-architecture or autodetecting -a$arch has been passed and it should follow
other architecture changes file?
Have a very nice day!

Description:

Closes: 610689 622788
Changes:
sbuild (0.63.0-1) unstable; urgency=low
.
[ Wookey ]
* Support for cross-compiling has been added. This includes the
addition of $host and $build configuration variables, with
corresponding --host and --build command-line options. This
includes the addition of a new 'xapt' dependency resolver.
- Merge cross-build support (thanks to Hector Oron,
Closes: #610689).
- Add multiarch cross-build support.
.
[ Roger Leigh ]
* The deprecated 'internal' dependency resolver has been removed,
along with the configuration variables $apt_policy,
$check_depends_algorithm and $resolve_virtual, and the
command-line option --check-depends-algorithm. The 'apt'
resolver is the default replacement for 'internal'.
(Closes: #622788)
* Support for watches has been removed. The configuration
variables $check_watches, $ignore_watches_no_build_deps and
$watches (and obsolete variables @ignore_watches_no_build_deps
and %watches) have also been removed.
* sbuild-stats and support for build time and space statistics
recording has been removed. These statistics are recorded in
both the build log and are available as build metadata
internally. The statistics recorded in the database were not
particularly informative; storing the statistics in a proper
relational database is recommended. The configuration variables
$avg_time_db and $avg_space_db have been removed.
* Drop 25nssdatabases schroot setup script used on compatibility
mode (on buildds). This has been replaced by the schroot
20nssdatabases for many years.
