What's possible is that not all packages specify CFLAGS (although you'd expect that to be fixed by now), or not for all files that are built. If that happens, you'll end up with ARMv5 insns, since the Fedora/ARM gcc generates v5 code by default (I think this is the default in gcc 4.1 for EABI). > I tried this too but kept hitting circular dependencies, especially > with Java. This will always be the case, but you don't need to re-bootstrap to build an ARMv4 version of the distro, right? Just build all packages for v4 in a v5 chroot, then build a new chroot out of the v4 packages you've just built. cheers, Lennert _______________________________________________ fedora-arm mailing list fedora-arm@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-arm
