[Error] Error while loading shared libraries

This post is written by YoungJ-Baek

1. Preface

There are two types of library, static and dynamic. Sometimes, you may face an error related to shared libraries even though you have built it well. It’s because you have compiled and built it well, but it has been built in the user path, /usr/local/lib

2. Error

The error log below is an example of my case, libpango_windowing.so problem.

Error Log

error while loading shared libraries: libpango_windowing.so: cannot open shared object file: No such file or directory

3. Solution

3.1. make configuration file

Command

$ cd /etc/ld.so.conf.d/
$ sudo vi libpango_windowing.conf

You can replace libpango_windowing.conf with your problematic shared library in form of lib{xxxxxx}.conf. Then, type the line below in the configuration file.

lib{xxxxx}.conf

/usr/local/lib

Then, type the command below after saving the configuration file

Command

$ sudo /sbin/ldconfig

3.2. Add Library Path

Add library path in the prompt or profile.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:{library path}
