1 centos(以centos6.0为例)：

(1) 可通过rpm -qa | grep glibc查看系统目前安装了哪些和glibc有关的包：

[root@Cluster ~]# rpm -qa | grep glibc

glibc-2.12-1.47.el6_2.12.i686

glibc-headers-2.12-1.47.el6_2.12.x86_64

glibc-common-2.12-1.47.el6_2.12.x86_64

glibc-devel-2.12-1.47.el6_2.12.x86_64

glibc-2.12-1.47.el6_2.12.x86_64

可以看到系统上glibc的版本号为2.12。

如果想进一步查看，可通过rpm -qi glibc：

[root@Cluster ~]# rpm -qi glibc

Summary : The GNU libc libraries

Description :

The glibc package contains standard libraries which are usedby

multiple programs on the system. In order to save disk spaceand

memory, as well as to make upgrading easier, common system codeis

kept in one place and shared between programs. This particularpackage

contains the most important sets of shared libraries: thestandard C

library and the standard math library. Without these twolibraries, a

Linux system will not function.

(2) 也可以通过查看ls -l /lib/libc.so.6输出结果：

[root@Cluster ~]# ls -l /lib/libc.so.6

lrwxrwxrwx. 1 root root 12 5月 21 17:46 /lib/libc.so.6 ->libc-2.12.so

2 ubuntu(以ubuntu11.04为例):

(1) 查看 ls -l /lib/i386-linux-gnu/libc.so.6的输出：

wzw@wzw-Lenovo:～$ ls -l /lib/i386-linux-gnu/libc.so.6

lrwxrwxrwx 1 root root 12 2012-07-15 09:14/lib/i386-linux-gnu/libc.so.6 -> libc-2.13.so

(2) 也可以使用 apt-cache show libc6:

wzw@wzw-Lenovo:~$ apt-cache show libc6

3 发行版无关方法：

(1) 查看ldd –version的输出结果：

wzw@wzw-Lenovo:~$ ldd –version

ldd (Ubuntu EGLIBC 2.13-0ubuntu13) 2.13

由 Roland McGrath 和 Ulrich Drepper 编写。

(2) 编译执行如下程序：

#include

int main(void)

{

puts(gnu_get_libc_version ());

return 0;

}

wzw@wzw-Lenovo:~$ ./a.out

2.13
