[libvirt] Problems in using Storage APIs in libvirt

Hi, I am getting the following the error when I try to use ANY storage related APIs. undefined reference to '<method name>' for example, undefined reference to virConnectListStoragePools. I checked in the libvirt.h and it has the method definition. I checked the libvirt.c and it has the implementations. I can not figure out why I get this error. I could use APIs related the network, for example virConnectListNetworks. Where could I have gone wrong and what are the work-arounds to solve them? I am using SLES 10 SP2. Thanks in advance, Amudhan.
