You do that in ~/.bashrc. On a new line, just enter:

export LIBRARY_PATH=<path to your library files>:$LIBRARY_PATH

Then, run source ~/.bashrc to enable anything you've added there.

  • For clarification: the `:$LIBRARY_PATH` part appends anything that was previously set in the old variable into the new one. – gustafbstrom Jul 06 '15 at 12:16
  • using `export` doesn't change the variable permanently, it just set it in active shell. – Luminous Jul 06 '15 at 12:21
  • Then, try changing `/etc/environment`, supposing by "permanent" you mean "system-wide"; see https://help.ubuntu.com/community/EnvironmentVariables#System-wide_environment_variables for details. – gustafbstrom Jul 06 '15 at 13:49
