The simple approach would be to just take all SRPMS in the f8/f9 distro, and do "rpmbuild --target armv4l foobar.src.rpm" for each of them. Unfortunately, that won't work 100%. What sometimes happens is that if package foobar was built against some version of libdependency, and libdependency was later upgraded a new version that breaks the foobar build, then that won't be caught until a new version of foobar is uploaded (or a security update needs to be issued, etc). (In Debian land, this is called a FTBFS (Fails To Build From Source) bug, which tend to get a lot of attention. When I bootstrapped Debian for ARM EABI, I didn't really run into a lot of packages that had such issues, but e.g. in Fedora 8 there were quite a number of them -- actually, probably the most work involved in bootstrapping Fedora/ARM was dealing with packages that wouldn't rebuild anymore even on x86.) (Some googling does turn up this page: http://fedoraproject.org/wiki/FTBFS -- so maybe it'll be easier for Fedora 9/10.) The idea here is that if you are a secondary Fedora architecture, you should build packages in the same order and with the same dependencies and dependency versions as they were built with on x86. Dennis Gilmore wrote some tools that can do exactly this -- which should really be set up for ARM as well. Actually, I think Dennis has set up a koji instance for ARM, so if you want to try to use this to rebuild f8 for armv4l, that would probably be a good test of the system. And it should dramatically reduce the amount of work you'll need to do to get an ARMv4 Fedora up and running. _______________________________________________ fedora-arm mailing list fedora-arm@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-arm
