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

Keep the previous path, don't overwrite it:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your/custom/path/

You can add it to your ~/.bashrc:

echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your/custom/path/' >> ~/.bashrc
