Actually -static-pie. -static-pie is different from -static -pie (with a space): $ cc -static-pie hw.c $ file a.out a.out: ELF 64-bit LSB pie executable, x86-64, version 1 (GNU/Linux), static-pie linked, for GNU/Linux 6.10.0, with debug_info, not stripped $ cc -static -pie hw.c $ file a.out a.out: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, for GNU/Linux 6.10.0, with debug_info, not stripped >From a "normal programmer" perspective, ASLR is performed for the former, but not the latter. In the former the load address of the executable is unknown, so some relocs are turned to R_X86_64_RELATIVE by ld, and Glibc rcrt1.o is linked in to resolve R_X86_64_RELATIVE at program startup. In the latter the load address is fixed, so all relocs are just resolved by ld, nothing is turned to R_X86_64_RELATIVE.
