Weird, this lib is an oracle lib..and the installer is looking for it in the wrong location. I’ll link this lib in the general lib location where it always can be found: /usr/lib.

这个库是oracle的一个库 并不是放在/usr/lib下 所以gcc找不到路径
我明白了，是gcc找不到，于是我在/usr/lib下做了软连接
ln -s $ORACLE_HOME libclntshcore.so.19.1 libclntshcore.so
说白了就是保证/usr/lib下目录面有 libclntshcore.so文件
