Linux "libxx cannot open shared object file no such file or directory"解决方案

This is a patch/enhancement about http://debug.aquariuslt.com/2015/12/14/libclntsh-so-11-1-cannot-open-shared-object-file/

Description

I was install Ubuntu 15.10 for tasting the new version of Ubuntu.
After setting up MEAN development and run node.js program.

Node.js throw error belows:

libaio.so cannot open shared object file no such file or directory

I try to find this in oracle instant client directory, but there is no file named this in it.
Then I power on the Ubuntu 14.04 and type command

locate libaio.so

It can be found in /lib/x86_64_linux_gnu
But not found in UBuntu 15.10

RootCause

That’s because Ubuntu 15.10 use different gnu/g++ version from Ubuntu 14.04.

Solution

You can follow these steps to locate the root cause and solve it.

1. Using command locate {filename} to search .so file.
   If result is empty, you can try below;

2. Install the *.so file.
   Using command

   sudo apt-get install {filename without .so}

or

If you found there is the same filename prefix but with version number,
for example,the error tips libaio.so not found, but you found there is a file named libaio.so.11.2 in /lib/x86_64_linux_gnu
you can make a softlink
using command

ln -s libaio.so.11.2 libaio.so
sudo updatedb
