以ARM32开发板为例，在/lib下有一个名为ld-linux-armhf.so.3的可执行程序（在ARM64开发板上是/lib/ld-linux-aarch64.so.1），这个程序负责加载可执行程序以及依赖的动态库：
# /lib/ld-linux-armhf.so.3 Usage: ld.so [OPTION]... EXECUTABLE-FILE [ARGS-FOR-PROGRAM...] You have invoked `ld.so', the helper program for shared library executables.
This program usually lives in the file `/lib/ld.so', and special directives
in executable files using ELF shared libraries tell the system's program
loader to load the helper program from this file. This helper program loads the shared libraries needed by the program executable, prepares the program to run, and runs it. You may invoke this helper program directly from the command line to load and run an ELF executable file; this is like executing that file itself, but always uses this helper program from the file you specified, instead of the helper program file specified in the executable file you run. This is mostly of use for maintainers to test new versions of this helper program; chances are you did not intend to run this program. --list list all dependencies and how they are resolved --verify verify that given object really is a dynamically linked object we can handle --inhibit-cache Do not use /etc/ld.so.cache --library-path PATH use given PATH instead of content of the environment variable LD_LIBRARY_PATH --inhibit-rpath LIST ignore RUNPATH and RPATH information in object names in LIST --audit LIST use objects named in LIST as auditors
然后使用--list参数就可以查看依赖的库：
# /lib/ld-linux-armhf.so.3 --list /usr/bin/stressapptest linux-vdso.so.1 (0xbeeef000) librt.so.1 => /lib/librt.so.1 (0xb6ece000) libpthread.so.0 => /lib/libpthread.so.0 (0xb6eaa000) libstdc++.so.6 => /lib/libstdc++.so.6 (0xb6d9f000) libm.so.6 => /lib/libm.so.6 (0xb6d23000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb6cfa000) libc.so.6 => /lib/libc.so.6 (0xb6c0d000) /lib/ld-linux-armhf.so.3 (0xb6ee4000)
此外，也可以使用readelf来查看库的依赖关系：
readelf -a <可执行程序> | grep NEEDED
完。
