version `GLIBCXX_3.4.21' not found 解决办法

在安装cmake3.5.1运行./bootstrap的时候出现如下提示：

gmake: “cmake”是最新的。
/usr/soft/cmake-3.5.1/Bootstrap.cmk/cmake: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /usr/soft/cmake-3.5.1/Bootstrap.cmk/cmake) ---------------------------------------------
Error when bootstrapping CMake:
Problem while running initial CMake

缺少GLIBCXX_3.4.21，或更高版本
为了核实版本问题：

[root@DESKTOP-RCOA9NR cmake-3.5.1]# strings /usr/lib64/libstdc++.so.6|grep GLIBCXX
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6

GLIBCXX_3.4.16
GLIBCXX_3.4.17
GLIBCXX_3.4.18
GLIBCXX_3.4.19

当前的版本的没有发现GLIBCXX_3.4.21，但是我刚装个gcc5.3.0
顺着gcc的安装路径，找到了新的libstdc++：

这里该有的都有了，把这份软链到正确的地方，就好了。

cp /usr/local/lib64/libstdc++.so.6.0.21 /usr/lib64/
cd /usr/lib64/
rm -f libstdc++.so.6
ln -s libstdc++.so.6.0.21 libstdc++.so.6
[root@DESKTOP-RCOA9NR lib64]# ll libstdc*
lrwxrwxrwx. 1 root root       19 4月   7 23:43 libstdc++.so.6 -> libstdc++.so.6.0.21
-rwxr-xr-x. 1 root root   995840 11月 19 22:20 libstdc++.so.6.0.19
-rwxr-xr-x. 1 root root 11093843 4月   7 23:39 libstdc++.so.6.0.21

至此再次运行
./bootstrap
gmake
make install
cmake安装完毕
