Kernel Compile flag not support by the Ubuntu 14.04 default arm-linux-gnueabihf-gcc

[tonyho]

As the Readme.md said, when trying to compile the kernel, errors:

 Makefile:660: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler
arm-linux-gnueabihf-gcc: error: unrecognized command line option ‘-fstack-protector-strong’
make[2]: *** [scripts/mod/empty.o] Error 1
make[1]: *** [scripts/mod] Error 2

same issue

I got the same error -- it needs 4.9 version.
I updated gcc and gcc-arm-linux-gnueabihf to 4.9 and was able to proceed ahead in compilation on Ubuntu 14.04

since you synced android code, you can use prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9/bin/arm-linux-androidkernel- to build kernel, arm-linux-gnueabihf-gcc is not needed.

The issue will be closed, as a solution was proposed by vickyggin and bing-mao.
Thanks guys!
