after downloading kernel 2.6.14.6 and grsecurity patch
2.1.8, untarring them and patching the kernel
when trying to compile it with grsecurity enabled I get multipple errors like

any ideas ?

Mhh let me guess - you have an system with an propolice patched gcc (for example gentoo hardend or adamantix)?

It depends on your distri how to disable it (-fno-stack-protector is the magic word)
