They only require things from the 32bit glibc-devel package and in koji there is a special 'glibc32' package that is an x86_64 rpm in the repos, that has a copy of the 32bit stuff needed. I'd prefer we didn't extend that hack, in fact koji upstream is looking at ways they could hardcode a few packages to have both ix86 and x86_64 packages put into the x86_64 repos that koji makes (likewise ppc64, s390x, so on so forth). Not full multilib as that would be very time consuming, but just enough to kill the fake packages. If your package was built in x86_64 but with access to the 32bit content, what is the resulting rpm, is it x86_64, or ix86? If it's ix86, the "best" thing would likely to exclusivearch it to ix86, and file a ticket for a multilib hardcoding so that it'll be copied into the x86_64 repo, like wine is. I also hate these hacks, as I'd rather see effort put into making the code work, if the software itself is generally useful. If its not generally useful, then does it really belong in Fedora, let alone hacked around to force it to be multilib ? -- Jesse Keating Fedora -- Freedom² is a feature! identi.ca: http://identi.ca/jkeating
