 Posted: Wed Mar 14, 2018 6:34 am Post subject: [solved]Kernel Build Fails: Kbuild does not support PIC mode |
 |
|
Hi all,
I am having some troubles after the 17.0 upgrade. In particular with the -PIC flag on the new gcc 6+ compiler and building the kernel.
I am experiencing the same symptoms from https://bugs.gentoo.org/621848.
I have corrected all emerge errors and every package has been rebuilt successfully on my system. However the problem comes when attempting to add new kernel flags.
After doing `make menuconfig` and selecting a few new options, when I go to do `make` I get:
| Code: |
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h
CHK include/generated/utsrelease.h
CC kernel/bounds.s
kernel/bounds.c:1:0: error: code model kernel does not support PIC mode
/*
make[1]: *** [Kbuild:45: kernel/bounds.s] Error 1
make: *** [Makefile:986: prepare0] Error 2
|
After extensive searching and trying the fixes suggested in various forum threads and the above bug thread, nothing has resolved my issue.
I also noted the bug thread was marked as 'Fixed and Resolved', yet I did not see where or how. Thinking it may just be in the most recent Linux tree, I re-emerged the Linux sources and tried to upgrade to Linux-4.9, but to no avail.
Any help would be highly appreciated.

grellyd,
4.4.6-gentoo is an old kernel. Update it. Current stable is 4.9.76-r1

Mmm I don't see that, thanks NeddySeagoon.
grellyd probably changing with a newest kernel is the best solution, forgets my workarounds

Thanks for the replies you two. The kernel upgrade was one of the last things that I tried. That also doesn't build.
Currently I get:
| Code: |
/usr/src/linux # eselect kernel list
Available kernel symlink targets:
[1] linux-4.4.6-gentoo
[2] linux-4.9.76-gentoo-r1 *

make[1]: *** Waiting for unfinished jobs....
HOSTCC scripts/selinux/mdp/mdp
make: *** [Makefile:545: scripts] Error 2
make: *** Waiting for unfinished jobs....
|
which seems to be the same error as before?
The one thing I have not tried yet is nuking the directory as suggested in https://wiki.gentoo.org/wiki/Kernel/Upgrade#Solving_build_problems. I'll try that next. |

While looking back at your comment @fedeliallalinea | Quote: | | Remove CONFIG_CC_STACKPROTECTOR_STRONG from kernel config |
I wanted to see if it was set, and how I could remove it. So I grepped the file.
| Code: | /usr/src/linux # grep STACKPROTECTOR .config
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
|
Does this look correct for a 4.9 Kernel? 'STRONG' does not appear to be set.
Could I have made an error while upgrading my kernel? |

Ah that makes sense. Otherwise I'm still in the wrong directory.
I'll try that now. It seems promising.
I missed that on https://wiki.gentoo.org/wiki/Kernel/Upgrade I'll put in a wiki edit. |
