Subject: [patch 04/10] tools/testing/selftests/exec: fix link error
Date: Sat, 22 May 2021 17:41:53 -0700	[thread overview]
Message-ID: <20210523004153.DEHj60j2v%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210522174113.47fd4c853c0a1470c57deefa@linux-foundation.org>

From: Yang Yingliang <yangyingliang@huawei.com>
Subject: tools/testing/selftests/exec: fix link error

Fix the link error by adding '-static':

gcc -Wall  -Wl,-z,max-page-size=0x1000 -pie load_address.c -o /home/yang/linux/tools/testing/selftests/exec/load_address_4096
/usr/bin/ld: /tmp/ccopEGun.o: relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `stderr@@GLIBC_2.17' which may bind externally can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: /tmp/ccopEGun.o(.text+0x158): unresolvable R_AARCH64_ADR_PREL_PG_HI21 relocation against symbol `stderr@@GLIBC_2.17'
/usr/bin/ld: final link failed: bad value
collect2: error: ld returned 1 exit status
make: *** [Makefile:25: tools/testing/selftests/exec/load_address_4096] Error 1
