Re: use objcopy to patch or poke an elf file?

There already is a checksum creation capability in the linker. (See the documentation for the --build-id switch in the linker manual). If none of the methods for computing this value suit your needs then you could always add code for your own method.

Alternatively how about reading in the checksum from a separate file at runtime ? Not particularly robust I know, but nice and simple.

Hey Nick,
Thanks for the suggestion - my link to binutils documentation WAS stuck at 2.17 - no --build-id there. I'm
excited to see what other options I've been missing! I'll explore ways to work with the build-id. I like the
separate file idea, too, but I don't have an OS in this particular case.


Thanks to you and everyone else who contributes to this mailing list. Watching it has been
very informative.
John
