glibc2.12升级至2.15

1、操作系统版本

[root@localhost ~]# cat /etc/redhat-release 
#CentOS release 6.9 (Final)

2、当前glibc版本

[root@localhost ~]# /lib64/libc.so.6 
GNU C Library stable release version 2.12, by Roland McGrath et al.

3、安装glibc2.15

[root@localhost ~]# wget http://ftp.gnu.org/gnu/glibc/glibc-2.15.tar.gz
[root@localhost ~]# tar zxf glibc-2.15.tar.gz
[root@localhost ~]# ./glibc-2.15/configure  --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
[root@localhost ~]# make
[root@localhost ~]# make install

PS：如果进入glibc源码目录再执行./configure会报错

4、查看安装之后的版本

[root@localhost ~]# /lib64/libc.so.6 
GNU C Library stable release version 2.15, by Roland McGrath et al.
[root@localhost ~]# strings /lib64/libc.so.6 | grep GLIBC
