确定Linux二进制文件的直接共享对象依赖关系? [英] Determine direct shared object dependencies of a Linux binary?

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
 ...
