Hi All,

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

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

Thanks,
Kamenee

The issue is clear: your compiler doesn't support that option.

The example config file [0] on the wiki page has 

CONFIG_HAVE_CC_STACKPROTECTOR=y
# CONFIG_CC_STACKPROTECTOR is not set
CONFIG_CC_STACKPROTECTOR_NONE=y
# CONFIG_CC_STACKPROTECTOR_REGULAR is not set
# CONFIG_CC_STACKPROTECTOR_STRONG is not set

so I guess you should give that a try.

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.

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