本文介绍如何利用ldd工具在Linux环境下查看Oracle SQL*Plus的动态库依赖情况，并展示了如何使用-v选项获取更详细的版本信息。

ldd工具是一个在linux和unix操作系统里用来显示一个执行文件或共享库的动态依赖信息的。

ldd工具在解决类似error while loading shared libraries: libclntsh.so.9.0等错误是很好用。

下面是这个工具的用法：

[oracle@filesvr1 oracle]$ man ldd

LDD(1) LDD(1)

NAME

ldd - print shared library dependencies

SYNOPSIS

ldd [OPTION]... FILE...

DESCRIPTION

ldd prints the shared libraries required by each program or shared

library specified on the command line.

OPTIONS

--version

Print the version number of ldd.

-v --verbose

Print all information, including e.g. symbol versioning informa-

tion.

-d --data-relocs

Perform. relocations and report any missing objects (ELF only).

-r --function-relocs

Perform relocations for both data objects and functions, and

report any missing objects or functions (ELF only).

--help Usage information.

BUGS

ldd does not work on a.out shared libraries.

ldd does not work with some extremely old a.out programs which were

built before ldd support was added to the compiler releases. If you

use ldd on one of these programs, the program will attempt to run with

argc = 0 and the results will be unpredictable.
