How to set the environmental variable LD_LIBRARY_PATH in linux

Question

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

Then I have opened .bash_profile file: vi ~/.bash_profile

Answer 1

I do the following in Mint 15 through 17, also works on ubuntu server 12.04 and above:

sudo vi /etc/bash.bashrc 

scroll to the bottom, and add:

export LD_LIBRARY_PATH=.

All users have the environment variable added.
