Parasite creation started to fail with GCC 12: On x86_64 with: ./compel/compel-host hgen -f criu/pie/restorer.built-in.o -o criu/pie/restorer-blob.h Error (compel/src/lib/handle-elf-host.c:337): Unexpected undefined symbol: `strlen'. External symbol in PIE? On aarch64 with: ld: criu/pie/restorer.o: in function `lsm_set_label': /drone/src/criu/pie/restorer.c:174: undefined reference to `strlen' Line 174 is: "for (len = 0; label[len]; len++)" Adding '-ffreestanding' to parasite compilation fixes these errors because, according to GCC developers: "strlen is a standard C function, so I don't see any bug in that being used unless you do a freestanding compilation (-nostdlib isn't that)."
