Adding section to ELF file
c, elf, linux
Solution
There's a few (possibly) related answers in this question about ELF file headers. The accepted answer mentioned using `objcopy` to add sections to an ELF file, and the BSD bintools claims to have a BSD-licensed implementation of `objcopy` that might suit your needs.
Problem
I need to be able to add an arbitrary section to an ELF file. I cannot use GPL code in this program, so BFD is out of the question. I can use libelf/gelf to read sections, but the documentation is fairly sparse for these, and I cannot figure out how to add a section. Does anybody know how to do this? I would rather not write my own ELF code.
