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

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

cd /etc/profile.d
sudo touch myenv_vars.sh
sudo gedit myenv_vars.sh

Add this to the empty file, and save it.

export LD_LIBRARY_PATH=/usr/local/lib

Logout and login, LD_LIBRARY_PATH will have been set permanently.
