Package: pbuilder Version: 0.135 Apparently, it's possible to get a pbuilder chroot for x86 on an amd64 box with the following command line (thanks to Mithrandir)
pbuilder create --distribution sid --debootstrapopts "--arch=i386"
--basetgz /var/cache/pbuilder/base-i386.tgz --mirror
http://ftp.jp.debian.org/debian
This is actually enough to bootstrap a i386 chroot.
On building a package, there is one extra work to do.
uname will give architecture string for amd64 (x86_64)
instead of i386. The tool for changing 'personality'
in amd64 is 'linux32'.
sbuild invokes linux32 before dpkg-buildpackge.
(thanks to neuro)
The missing piece for pbuilder amd64->i386 cross build
support is
1. documentation on the procedure
2. support for linux32
3. regression testsuite to test that
a. bootstrap is functional
b. build is getting uname -a with correct values
c. package gets built
