Adrien: I took the same one and got kernel built. If you have your failing tree somewhere then please provide me which exactly version it is and kernel configuration you built. If you can then please test it under Ubuntu 12.04 - it has more up-to- date cross compiler which should just work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/947111 Title: -march bug when building kernel To manage notifications about this bug go to: https://bugs.launchpad.net/binutils/+bug/947111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

NB that that asflags thing is just a work around, not an actual fix. This bug was addressed in the toolchain: http://sourceware.org/bugzilla/show_bug.cgi?id=12698 and seems to be fixed in at least some of the linaro toolchain packages -- maybe it just failed to get into the lucid one somehow? ** Bug watch added: Sourceware.org Bugzilla #12698 http://sourceware.org/bugzilla/show_bug.cgi?id=12698 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/947111 Title: -march bug when building kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/947111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
