KEIL生成的ELF格式文件分析

ARMCC库的分离方法

【库是以AR格式存放的】

惭愧，还是没结果，唉，还是希望能有人能解答，总觉得做技术还是深究一步的好。

为了鼓励看贴的同仁，附上对KEIL C语言的运行库分析步骤：

1.可从 map文件中查到你的程序中用到哪些库中的函数及在哪个库中

2.运行库的目录为：keil\arm\rv31\lib\armlib

3.用armar -x 命令从库中解出相应的.o文件

4.用fromelf -c 命令反汇编相应的.o文件，也可加-output 来何在反汇编结果到文件中

具体命令参数可直接打命令查看


【ELF格式现在不仔细分析，等学到GCC的时候再去分析】

【不过学GCC之前要去学linux应用开发和BSP开发，还有很多路要走】
