I've done the following command to set the path for LD_PRELOAD. But it's the wrong path.

export LD_PRELOAD=/home/

Does anyone know what is the default path for LD_PRELOAD on Ubuntu 12.04? What is the exact command to reset the export?

There is no default LD_PRELOAD variable, or, in other words, it is empty. You can revert to that state by typing

unset LD_PRELOAD

LD_PRELOAD is not to specify the libraries found in the regular case; it is just here to specify an order of library loading that is different from the regular one (determined by ldconfig(8)).

after i've entered unset LD_PRELOAD, i'm still getting the Platform/ERROR: ld.so: object '/' from LD_PRELOAD cannot be preloaded: ignored –  alvas Sep 18 '12 at 8:38
    
What are you trying to run? My bet would be that you are running a script that tries to set up its own LD_PRELOAD and fails. –  January Sep 18 '12 at 8:46
