Is there any way to build amd64 packages from i386?
There is probably more than one way, but assuming you have a 64-bit
processor (if not, why would you want to build packages for it?), the
easiest solution is to boot with a 64-bit kernel and set up an amd64
chroot for that task with "debootstrap --arch=amd64 --variant=buildd".
You can also set up pbuilder for amd64, look for the --debootstrapopts
option in the pbuilder manpage.
Ahmmm...
Thanks for helping me, but I got a little bit confused by this explanation.
I got a package: package_0.0.0_i386.deb
And I want: samepackage_0.0.0_amd64.deb
Okay, it seems I completely misunderstood you. I thought you wanted to
build packages from source.
I know I can install i386 packages by the --force-architecture
parameter, but what I really need is to build one.
I'm used to build my own packages with checkinstall, but they're not
providing me the source for this specific package.
Here is a way to just hack the architecture in foobar_i386.deb, with
short comments:
# We want the files in the control.tar.gz to be owned by root, so let's
# pretend we are root; apt-get install fakeroot if necessary.
fakeroot /bin/bash
# extract the files in the control archive into a scratch dir
mkdir scratch
ar x foobar_i386.deb control.tar.gz
tar -C scratch -xzvf control.tar.gz
# change the Architecture in the control file
sed -i -e 's/Architecture: i386/Architecture: amd64/' scratch/control
# regenerate the control archive
GZIP=-9n tar -C scratch -cvzf control.tar.gz .
# replace the control archive in the .deb
ar rav debian-binary foobar_i386.deb control.tar.gz
# clean up and exit the fakeroot shell:
rm -rf scratch control.tar.gz
exit
