| 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 |
