可用的ELF可执行文件需要哪些部分? [英] What sections are required for a usable ELF executable?

问题描述

我正在创建一个ELF可执行文件，我需要知道操作系统需要哪些部分才能加载和执行该文件.

I'm creating an ELF executable file and I need to know what sections are required by the operating system in order to load and execute it.

详细信息:

Details:

OS:               Ubuntu 10.04 (64-bit)
Kernel version:   2.6.32-24
Architecture:     i386

我意识到以下可能是必要的:

I realize that the following would probably be necessary:
