How to add <install_dir>/lib to LD_LIBRARY_PATH if already entry is there?
 

I already have LD_LIBRARY_PATH setup in my /etc/profile as:

Now there is a request to add a new entry for LD_LIBRARY_PATH.
export LD_LIBRARY_PATH=$PATH:/opt/tptp/em64/lib

But If I add that to profile file,when I do:

cd $LD_LIBRARY_PATH

It will contradict.
Whats the solution?

Evo2.

export LD_LIBRARY_PATH=/usr/local/lib .. : will add a path.


export LD_LIBRARY_PATH=$PATH:/opt/tptp/em64/lib

.. will exclude the other paths. Very handy in some
occasions, but usually only to be used temporarary,
unless all other paths are included in that line :

... :/opt/tptp/em64/lib:/lib:/usr/lib: , etc.
