Thread: Can´t build kernel 4.14.15

  1. #1

    Default Can´t build kernel 4.14.15

    I hope this is the right subforum to ask for kernel stuff....

    I try to build the latest kernel from the stable kernel repo that is 4.14.15-5.
    But it always fails, I always get a segfault in objtool at some point.

    Some people suggest RETPOLINE to be the bad guy that segfaults objtool.
    Thus, I disabled RETPOLINE, but did not help either...

    Then I tried to use CONFIG_UNWINDER_FRAME_POINTER=y and disable RETPOLINE the same time, did not help again.

    I´m a bit displaired now, any suggestions?
    Though, I use march=bdver2 to optimize for AMD FX. Could this cause trouble?

    System used:
    Leap 42.3
    GCC7 gcc 7.3.0
    AMD FX CPU with march=bdver2

    I think I might only be able to build 4.14.15-5 with

    CONFIG_UNWINDER_FRAME_POINTER=y
    # CONFIG_RETPOLINE is not set

    But, I´d like to have retpoline activated.....
