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 This is a really dirty hack, though. A better framework for converting i386 packages is developed in the ia32-libs-tools package, available in unstable¹. While this tool is not very mature and barely documented, it is probably a better way than just changing the Architecture: field in debian/control.
