linker - 如何查看共享库加载顺序

Question

给定一个 ELF 二进制文件或共享对象，我如何才能最轻松地查看所需共享库的加载顺序？

它们是否按照 readelf -d 列出的顺序加载？

Answer 1

how can I most easily see the order in which the needed shared libraries will be loaded?

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 man ld.so。

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

不一定它会受到预加载(LD_PRELOAD、/etc/ld.so.preload)的影响。
