(That doesn't mean that you can't build an old-ABI toolchain from the same SRPM that the prebuilt toolchain above was built from.) > and since making them usable requires using a different ABI If you insist on using the prebuilt toolchain binary rpms that have been built for EABI, then yes, you'll need to use EABI on your target board as well. > the default Fedora glibc will never be usable on the gp2x, The prebuilt Fedora/ARM glibc is EABI and won't run on old-ABI systems, yes. > unless someone updates the kernel. Correct? You need at least 2.6.something to be able to run an EABI userland on your ARM board, yes. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
