Im using Slackware 10.2.0 and i just try to compile the new kernel with the latest grsecurity ptach.
And i got these errors on make:

Code: Select all: CHK include/linux/version.h CHK include/linux/utsrelease.h CALL scripts/checksyscalls.sh CHK include/linux/compile.h MODPOST vmlinux WARNING: arch/i386/kernel/built-in.o(.exit.text+0x26): Section mismatch: reference to .init.text: (after 'cache_remove_dev') WARNING: kernel/built-in.o(.text+0x14c52): Section mismatch: reference to .init.text: (between 'kthreadd' and 'init_waitqueue_head') WARNING: drivers/built-in.o(.text+0x41e63): Section mismatch: reference to .init.text: (between 'sis900_probe' and 'sis900_default_phy') OBJCOPY arch/i386/boot/compressed/vmlinux.bin /bin/sh: line 1: 12876 File size limit exceededobjcopy -O binary -R .note -R .comment -S vmlinux arch/i386/boot/compressed/vmlinux.bin make[2]: *** [arch/i386/boot/compressed/vmlinux.bin] Error 153 make[1]: *** [arch/i386/boot/compressed/vmlinux] Error 2 make: *** [bzImage] Error 2

Probably it is not a grsecurity problem... but i can't understand where is the problem. If anyone knows something please help.

can you post readelf -e vmlinux and maybe the interesting parts of your .config?

Thanks for the answer and help PaX Team!

i don't see anything immediately wrong, so my next guess is that your binutils could be old, if it's <2.17, could you upgrade it and try again?

Thanks so much.. it works

I upgrade my old binutils-2.15.92.0.2-i486-3 with the new binutils-2.17.50.0.17-i486-1 for slack 12.0
I hope all gonna work fine, without troubles caused by this new binutils version.
