解决CentOS6.2中缺失GLIBC_2.14版本的问题-优快云博客

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：

 
        [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：

        [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

 
        [root@localhost nvEncodeApp]
        # export LD_LIBRARY_PATH=/opt/glibc-2.14/lib:$LD_LIBRARY_PATH
       
        [root@localhost nvEncodeApp]
        # ./nvEncoder
