python3 setup.py install

API

Creating new object

from makeelf.elf import *
elf = ELF(e_machine=EM.EM_LKV373A)
print(elf)

Parsing ELF file

fd = os.open('some.elf', os.O_RDONLY)
b = os.read(fd, 0xffff)
os.close(fd)
elf, b = Elf32.from_bytes(b)
print(elf)

Saving ELF to file

fd = os.open('other.elf', os.O_WRONLY | os.O_CREAT | os.O_TRUNC)
os.write(fd, bytes(elf))
os.close(fd)

Adding a section

data_id = elf.append_section('.data', b'\0\0\0\0', 0xfadd)

Adding a symbol

elf.append_symbol('NULL', data_id, 0, 4)

Modifying attributes

elf.Elf.Shdr_table[data_id].sh_flags = int(SHF.SHF_ALLOC)
