 Posted: Mon Nov 16, 2015 11:13 pm Post subject: Stuck on building hardened 4.2.6-r3 w/ PaX & grsec |
 |
|
I am trying to build hardened kernel, but keeps erroring out early on in make.
I can build a non hardened kernel perfectly fine.
Not sure what to do here...
Trying to make after make menuconfig results in this.

Tried to install kbuild but that didn't work either.

I am following the handbook directly, but activated a few more PaX functions, so maybe that's it? Any help would be greatly appreciated.
P.S. this is a ppc32 machine if that makes a difference. |

reinstalled hardened-sources and even tried with genkernel... still nothing! is the ppc kernel broken or am i doing something wrong?

Moved from Installing Gentoo to Gentoo on PPC.
Probably a better fit here.
In your first post, | Code: | ./arch/powerpc/include/asm/spinlock.h: In function ‘__arch_read_trylock’:
./arch/powerpc/include/asm/spinlock.h:226:2: error: expected ‘:’ or ‘)’ before ‘_ASM_EXTABLE’
_ASM_EXTABLE(2b,4b) |
appears to be an error is the source code.
In your second post | Code: | | *cc1: all warnings being treated as errors |
is a bad thing.
I don't think I have ever seen a kernel build with no warnings.

That's what I thought, that it must be an error in the source code...
I definitely didn't see any option to treat all warnings as errors, which confused me, as that error still showed up even after I deleted .config and started over to be sure it wasn't a bad option breaking things.
I have built 4.0.9 non-hardened successfully again, so at least my machine is capable of compiling some kernel... Even 4.0.9 hardened would be nice but there is no hardened stage3 available for ppc. |

mckickflip,
Ask in #gentoo-hardened on freenode.net
