Hi All,

Hello,

I am referring to this wiki page (http://wiki.xen.org/wiki/HiKey) to
setup xen in hikey. I am currently facing problem in building linux (
android-hikey-linaro-4.1
<https://github.com/96boards/linux/tree/android-hikey-linaro-4.1> ),but
I am getting compile error as below:


kamenee@kamenee-Lenovo-Z51-70:~/hikey-build/linux$ make ARCH=arm64
CROSS_COMPILE=aarch64-linux-gnu- -j4
Makefile:660: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG:
-fstack-protector-strong not supported by compiler

Based on the description in the Kconfig (CC_STACKPROTECTOR_STRONG) is only supported by gcc version 4.9 or above, or a distribution gcc with the feature backported.

I am using gcc version 4.8 here. Does any one know how to solve this or
should I use specific linux repo ?

By either selecting a different stack protector mode or upgrading your compiler to at least gcc 4.9.
