The kernel is x86_64, with support for the x32 ABI, yes. > So that make me wonder if we really need to built the whole collection > as x32 ?

You can't link x32 binaries against i686/x86_64 libraries, etc. You need entirely separate userspace. From a Fedora perspective, the way to do that is to add an architecture to koji and build whatever you want. That arch add should start as secondary. josh -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
