Subject: [PATCH nolibc 01/14] tools/nolibc: always disable stack protector for tests
Date: Mon, 20 Mar 2023 18:11:24 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <6a3206d0-e5cd-4990-9604-444a24a8207c@paulmck-laptop>
From: Thomas Weißschuh <[email protected]>
Stack protectors need support from libc.
This support is not provided by nolibc which leads to compiler errors
when stack protectors are enabled by default in a compiler:
CC nolibc-test
/usr/bin/ld: /tmp/ccqbHEPk.o: in function `stat':
nolibc-test.c:(.text+0x1d1): undefined reference to `__stack_chk_fail'
/usr/bin/ld: /tmp/ccqbHEPk.o: in function `poll.constprop.0':
nolibc-test.c:(.text+0x37b): undefined reference to `__stack_chk_fail'
/usr/bin/ld: /tmp/ccqbHEPk.o: in function `vfprintf.constprop.0':
nolibc-test.c:(.text+0x712): undefined reference to `__stack_chk_fail'
/usr/bin/ld: /tmp/ccqbHEPk.o: in function `pad_spc.constprop.0':
nolibc-test.c:(.text+0x80d): undefined reference to `__stack_chk_fail'
/usr/bin/ld: /tmp/ccqbHEPk.o: in function `printf':
nolibc-test.c:(.text+0x8c4): undefined reference to `__stack_chk_fail'
/usr/bin/ld: /tmp/ccqbHEPk.o:nolibc-test.c:(.text+0x12d4): more undefined references to `__stack_chk_fail' follow
collect2: error: ld returned 1 exit status
