Subject: [Buildroot] [PATCH 2/2] kvm: Fix undefined reference to __stack_chk_fail()
Date: Mon,  6 Jun 2022 20:43:20 +0200	[thread overview]
Message-ID: <20220606184320.8210-3-petr.vorel@gmail.com> (raw)
In-Reply-To: <20220606184320.8210-1-petr.vorel@gmail.com>

Some x86_64 buildroot toolchains (bootlin-x86-64-glibc,
bootlin-x86-64-musl) try to link to __stack_chk_fail().
-nostdlib is not enough, it requires also -fstack-protector.

x86_64-buildroot-linux-gnu/bin/ld: /tmp/ccgBXEoR.o: in function `handle_page_fault':
kvm_pagefault01.c:(.text+0x5d): undefined reference to `__stack_chk_fail'
collect2: error: ld returned 1 exit status
