/lib64/libc.so.6: version `GLIBC_2.14' not found问题

今天运行一个例程，出现了/lib64/libc.so.6: version `GLIBC_2.14' not found问题，把解决过程简单记录一下。

系统环境： centos6.2 

现象：

 

?

1 2	[root@localhost nvEncodeApp]# ./nvEncoder  ./nvEncoder: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by ./nvEncoder)

 

 

 

好吧，人家需要的是'GLIBC_2.14'，先查看一下当前系统glibc的情况：

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

[root@localhost build]# strings /lib64/libc.so.6 |grep GLIBC GLIBC_2.2.5 GLIBC_2.2.6 GLIBC_2.3 GLIBC_2.3.2 GLIBC_2.3.3 GLIBC_2.3.4 GLIBC_2.4 GLIBC_2.5 GLIBC_2.6 GLIBC_2.7 GLIBC_2.8 GLIBC_2.9 GLIBC_2.10 GLIBC_2.11 GLIBC_2.12 GLIBC_PRIVATE

 

 

好吧，确实没有，那简单粗暴，安装一下。

 

1. glibc下载

从http://www.gnu.org/software/libc/ 下载源代码。我下载的版本是2.14，链接地址是http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz。

2. 安装

因为glibc库使用广泛，为了避免污染当前系统环境，最好自定义安装目录，使用时定义一下环境变量就行了。具体步骤如下：

 

?

1 2 3 4 5 6 7

[root@localhost ~]# tar xvf glibc-2.14.tar.gz [root@localhost ~]# cd glibc-2.14 [root@localhost glibc-2.14]# mkdir build [root@localhost glibc-2.14]# cd ./build [root@localhost build]# ../configure --prefix=/opt/glibc-2.14 [root@localhost build]# make -j4 [root@localhost build]# make install

 

 

3. 测试
