Hi,
I am a newbie to Boost. I am writing a sample code using the Boost libaries and am getting the following error during linking.

$LD_LIBRARY_PATH has the following value set. /home/suhas/boost/lib:/usr/lib:/usr/include/boost/
I am stuck, any help will be really appreciated.
Thanks in advance.
Regards, Eswar
