Some programs depned on libbpf.a(eg:bpftool). If libbpf.a miss -fPIC, this will cause a similar error at compile time: /usr/bin/ld: .../libbpf.a(libbpf-in.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 sharedobject; recompile with -fPIC Use -fPIC for static library compilation to solve this problem.
