Hi mondialeeer,
I am currently trying to embed an ELF into a larger ELF that will manage this
ELF (boostrap it and execute it).
Do you know about the ".incbin" assembler pseudo op which allows you to
insert an arbitrary file into a section ? You could use this to embed
your small ELF executable into the large ELF executable with symbols
defined exactly where you want them.
Extra information is inserted when trying to embed an ELF into a larger ELF.
This extra info makes the "start" and "end" labels useless
What "start" and "end" labels are you talking about ?
if code in the
larger ELF would like to jump to the beginning of the code section in the
embedded ELF.
For instance:
xdd -i small_elf.o small_elf.c
Note - xdd is not a binutils program so we cannot offer you any help
with using it.
Is this extra information the binary encoded symbol table of the ELF?
No idea. It is probably the ELF header information though. You should
have a look at the ELF standard and read up about the format of the header.
Cheers
Nick
