以centos7.4 为例，说明libstdc++.so.6.0.19 升级到libstdc++.so.6.0.24
ubuntu也可以通过这个进行libstdc++.so.6进行升级
libstdc++的代码是在gcc的代码中，需要下载gcc代码，对其进行编译安装，设置软连接
1 查看当前已经安装的glibc的版本
目前安装的是libstdc++.so.6.0.19

3. 编译gcc/libstdc++
3.1 准备依赖： 需要在gcc代码的根目录执行
这一步必须执行。
cd gcc-7.3.0

3.2 配置生成Makefile
mkdir build;cd build;
../configure –enable-checking=release –enable-languages=c,c++ –disable-multilib
–disable-multilib: 用于关闭多个多个arch的库，比如只需要64位的，不需要32位的库，那就添加这个配置
