error while loading shared libraries: libvl.so about vlfeat

Please tell me how to set that , thanks @vedaldi
UPDATE
sorry, I solved it by adding it to my bashrc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/zyr/vlfeat-0.9.20/toolbox/mex/mexa64/

Please make sure that either the DLL file is in the same directory of your executable or that it is in LD_LIBRARY_PATH. See for example:

I try to use g++ to compile the simplest "Hello World" program of vlfeat. My system is Ubuntu 12.04 LTS 64-bit.

I can compile successfully, but when I run it, it failed with message like this:
"error while loading shared libraries: libvl.so: cannot open shared object file: No such file or directory"

Anyone tell me how to fix it?

Open vlfeat/toolbox/mex/octave/mexa64
and open octave from that location
