添加部分ELF文件 [英] Adding section to ELF file

问题描述

我需要能够将任意部分添加到一个ELF文件。我无法使用GPL code在这个程序，所以BFD是出了问题。我可以使用libelf函数/ GELF阅读部分，但文档是这些相当稀疏，我无法弄清楚如何添加一个部分。是否有人知道如何做到这一点？我宁愿不写我自己的ELF code。

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.

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.
