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?
GCC7 gcc 7.3.0
**AMD FX CPU with march=bdver2
