/local_disk/sai/wpu_aug23/wpu-sw/src/common/utils/buildroot/output/host/usr/aarch64-buildroot-linux-gnu/sysroot/usr/lib/aarch64-linux-gnu/libm.a(k_standard.o)(.text+0x318):
unresolvable R_AARCH64_ADR_PREL_PG_HI21 relocation against symbol
`stderr@@GLIBC_2.17'

and sinc libm.a is not built with option "-fPIC", The error can come and libm.a is default generated part of buildroot and i cannot build here.

--- Comment #1 from Samuel Martin <[email protected]> --- To investigate this bug we need more details:
- Buildroot version
- Buildroot defconfig used leading to the situation
- opencv package built? (opencv or opencv3)
- is it a static only build?

Have you tried to run: 'make clean && make' ?

Have you tweak the opencv.mk (or opencv3.mk) file? if yes, how?

Have you build the toolchain, then change some critical configurations requiring a full rebuild [1]?
