The header structure
#define EINIDENT 16
typedefstruct{
unsigned char e_ident[EINIDENT];
Elf32_Half e_type;
Elf32_Half e_machine;
Elf32_Word e_version;
Elf32_Addr e_entry;
Elf32_Off e_phoff;
Elf32_Off e_shoff;
Elf32_Word e_flags;
Elf32_Half e_ehsize;
Elf32_Half e_phentsize;
Elf32_Half e_phnum;
Elf32_Half e_shentsize;
Elf32_Half e_shnum;
Elf32_Half e_shstrndx;
} Elf32Ehdr;
The 2nd e_version which defines the version as 1 (i.e. "current")
e_version This member identifies the object file version.
Name Value Meaning
EV_NONE 0 Invalid version
EV_CURRENT 1 Current version
The value 1 signifies the original file format; extensions will
create new versions with higher numbers. The value of EV_CURRENT,
though given as 1 above, will change as necessary to reflect the
current version number.
The version in the e_ident part is also EV_CURRENT, so exactly the same version:
EI_VERSION Byte e_ident[EI_VERSION] specifies the ELF header version
number. Currently, this value must be EV_CURRENT, as
explained above for e_version.
From what I understand, I would say that the version has not changed yet so it is still 1 in both places, but that could change in the future...
