如何查看共享库加载的顺序 [英] How to see the order of shared library loading

问题描述

鉴于ELF二进制或共享库，我如何最轻松地查看所需共享库的加载顺序?

Given an ELF binary or shared object, how can I most easily see the order in which the needed shared libraries will be loaded?

它们是否按照 readelf -d 列出的顺序加载?

Are they loaded in the order they are listed by readelf -d?

使用 LD_DEBUG :

LD_DEBUG=files /bin/ls
13444:
13444:     file=libc.so.6 [0];  needed by who [0]
...
13444:     file=libnss_files.so.2 [0];  needed by who [0]
...

有关更多信息，请参阅ld.so.

For more info man ld.so.

它们是否按照readelf -d列出的顺序加载?

Are they loaded in the order they are listed by readelf -d?

不一定是它会受到预加载( LD_PRELOAD ，/etc/ld.so.preload )的影响.

Not necessarily e.g. it will be influenced by preloading (LD_PRELOAD, /etc/ld.so.preload).
