Hi All,
Trying to build a hardened kernel, and getting the following:
| Code: | Makefile:732: Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong not supported by compiler
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h
CHK include/generated/utsrelease.h
CC kernel/bounds.s
gcc: error: unrecognized command line option '-fstack-protector-strong'
Kbuild:35: recipe for target 'kernel/bounds.s' failed
make[1]: *** [kernel/bounds.s] Error 1
Makefile:1052: recipe for target 'prepare0' failed
make: *** [prepare0] Error 2
|
How can I fix it?
Thanks,
SxN |

What version of gcc are you using (gcc --version) ... Try a newer version perhaps? Looks like it's new in gcc-4.9 ...

I thought of the gcc version too, so I did the followings:
| Code: | emerge --sync
emerge gcc
gcc --version
gcc (Gentoo Hardened 4.8.4 p1.5, pie-0.6.1) 4.8.4
|
I wasn't aware that I have to go up to 4.9, maybe I should try and install that version before compiling.
(I also updated make to 4.1)
