Yes, but... $ cc -static -Wl,-I/libexec/ld.elf_so -fpie -Wl,-pie pie.c -lc_pic 1. Our specs are broken for static and you need to explicitly specify the interpreter 2. You need to link against the pic version of libc $ file ./a.out ./a.out: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /libexec/ld.elf_so, for NetBSD 7.99.16, not stripped And it is not a "statically linked" binary. $ ldd ./a.out ./a.out: But it does not depend on any shared libraries, other than the dynamic linker itself... christos
