From e5decefd884da1c2c6ea18fca17b80b189afcc43 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Fri, 19 Mar 2021 16:53:25 +0000 Subject: kselftest/arm64: mte: Fix pthread linking The GCC manual suggests to use -pthread, when linking with the PThread library, also to add this switch to both the compilation and linking stages. Do as the manual says, to fix compilation with Ubuntu's 20.04 toolchain, which was getting -lpthread too early on the command line: ------------ /usr/bin/ld: /tmp/cc5zbo2A.o: in function `execute_test': tools/testing/selftests/arm64/mte/check_gcr_el1_cswitch.c:86: undefined reference to `pthread_create' /usr/bin/ld: tools/testing/selftests/arm64/mte/check_gcr_el1_cswitch.c:90: undefined reference to `pthread_join' ------------ Signed-off-by: Andre Przywara Reviewed-by: Mark Brown Link: https://lore.kernel.org/r/20210319165334.29213-3-andre.przywara@arm.com Signed-off-by: Catalin Marinas --- tools/testing/selftests/arm64/mte/Makefile | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'tools/testing/selftests/arm64') diff --git a/tools/testing/selftests/arm64/mte/Makefile b/tools/testing/selftests/arm64/mte/Makefile index df15d44aeb8d..90aadd86fa0d 100644 --- a/tools/testing/selftests/arm64/mte/Makefile +++ b/tools/testing/selftests/arm64/mte/Makefile @@ -1,7 +1,8 @@ # SPDX-License-Identifier: GPL-2.0 # Copyright (C) 2020 ARM Limited -CFLAGS += -std=gnu99 -I. -lpthread +CFLAGS += -std=gnu99 -I. -pthread +LDFLAGS += -pthread SRCS := $(filter-out mte_common_util.c,$(wildcard *.c)) PROGS := $(patsubst %.c,%,$(SRCS)) -- cgit v1.2.3-59-g8ed1b
