问题描述
如何轻松找出ELF格式的Linux二进制文件的直接共享对象依赖性?
How can I easily find out the direct shared object dependencies of a Linux binary in ELF format?
我知道ldd工具,但这似乎可以输出二进制文件的所有依赖项,包括二进制文件所依赖的任何共享对象的依赖项.
I'm aware of the ldd tool, but that appears to output all dependencies of a binary, including the dependencies of any shared objects that binary is dependent on.
推荐答案
您可以使用readelf
探索ELF标头. readelf -d
将直接依赖项列为NEEDED
部分.
You can use readelf
to explore the ELF headers. readelf -d
will list the direct dependencies as NEEDED
sections.
$ readelf -d elfbin
Dynamic section at offset 0xe30 contains 22 entries:
Tag Type Name/Value
0x0000000000000001 (NEEDED) Shared library: [libssl.so.1.0.0]
0x0000000000000001 (NEEDED) Shared library: [libc.so.6]
0x000000000000000c (INIT) 0x400520
0x000000000000000d (FINI) 0x400758
