大部分内容截取自uClinux-dist/linux-2.4.24/lib/libxxx中的相应说明,也有的google来的,不一定准确,仅供参考。

libAES, libDES, libSSL
-------------------------
加密/解密和实现SSL要用到的库,实际编译uClinux-dist/freeswan下的一些咚咚,IPSEC要用到这个。

libGMP
--------
library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers. 
用于任意精度的算术运算。

libG
-----
实际会编译termcap库,a library of C functions that enable programs to send control strings to terminals in a way independent of the terminal type.
用于向任意类型的终端发送字符串。

libldap
--------
LDAP(Lightweight Directory Access Protocol) is an Internet protocol that email and other programs use to look up information from a server.
如果程序用到LDAP协议需要这个。

libPAM
--------
Pluggable Authentication Modules for Linux, Is a system of libraries that handle the authentication tasks of applications (services) on the system.
用于对程序和服务的xxx认证。。。。

libpcap
--------
a system-independent interface for user-level packet capture, provides a portable framework for low-level network monitoring.
用于包捕获和分析,如果要跑网络分析、嗅探之类的程序需要用到这个。

libz

这个应该熟悉了,用于实现菜单模式的库,配置linux内核的时候如果使用make menuconfig就需要这个库。
