This code doesn't work as intended in python3, because magic[16] is an integer: magic[16] in (b'\x02', b'\x03') So is_prelinkable_elf always returns False for python3: $ python3 -c "from portage.checksum import is_prelinkable_elf print(is_prelinkable_elf('/bin/bash'))" False $ python2.7 -c "from portage.checksum import is_prelinkable_elf print(is_prelinkable_elf('/bin/bash'))" True
