You should add more details about your distribution, for example under Ubuntu the right way to do this is to add a custom <code>.conf</code> file to <code>/etc/ld.so.conf.d</code>, for example

<pre><code>sudo gedit /etc/ld.so.conf.d/randomLibs.conf
</code></pre>

inside the file you are supposed to write the complete path to the directory that contains all the libraries that you wish to add to the system, for example

<pre><code>/home/linux/myLocalLibs
</code></pre>

remember to add only the path to the dir, not the full path for the file, all the libs inside that path will be automatically indexed.

Save and run <code>sudo ldconfig</code> to update the system with this libs.

For some reason no one has mentioned the fact that the bashrc needs to be re-sourced after editing. You can either log out and log back in (like mentioned above) but you can also use the commands: <code>source ~/.bashrc</code> or <code>. ~/.bashrc</code>.

Put <code>export LD_LIBRARY_PATH=/usr/local/lib</code> in <code>~/.bashrc</code> [preferably towards end of script to avoid any overrides in between, Default <code>~/.bashrc</code> comes with many <code>if-else</code> statements]

You could try adding a custom script, say <code>myenv_vars.sh</code> in <code>/etc/profile.d</code>. 

<pre><code>cd /etc/profile.d
sudo touch myenv_vars.sh
sudo gedit myenv_vars.sh
</code></pre>

Add this to the empty file, and save it.

<pre><code>export LD_LIBRARY_PATH=/usr/local/lib

Logout and login, <code>LD_LIBRARY_PATH</code> will have been set permanently.

scroll to the bottom, and add:

<pre><code>export LD_LIBRARY_PATH=.
</code></pre>

All users have the environment variable added.

I have first executed the command: <code>export LD_LIBRARY_PATH=/usr/local/lib</code>

Then I have opened <code>.bash_profile</code> file: <code>vi ~/.bash_profile</code>.
In this file, I put:

<pre><code>LD_LIBRARY_PATH=/usr/local/lib
export LD_LIBRARY_PATH
</code></pre>

Then if the terminal is closed and restarted, typing <code>echo $LD_LIBRARY_PATH</code> displays no result.

How to set the path permanently?

我首先执行了命令：export LD_LIBRARY_PATH=/usr/local/lib然后我打开了.bash_profile文件：vi ~/.bash_profile。在这个文件中，我放入：LD_LIBRARY_PATH=/usr/local/libexport LD_LIBRARY_PATH然后，如果终端关闭并重新启动，则键入echo $LD_LIBRARY_PATH不会显示任何结果。如何
