Subject: [RFC PATCH] kbuild: add -fno-PIE
Date: Fri, 21 Oct 2016 13:16:00 +0200 [thread overview]
Message-ID: <20161021111600.9417-1-bigeasy@linutronix.de> (raw)
Debian started to build the gcc with --enable-default-pie by default so the
kernel build ends before it starts properly with:
|kernel/bounds.c:1:0: error: code model kernel does not support PIC mode
Is this okay or do we want some kind of check to see if -fno-PIE is supported?
It is mentioned in the 4.4.7 gcc manpage is it is not *that* new :)
