[libvirt] Compile time error in event-test.c

Hi... I am trying to compile the event-test.c code of the libvirt package. I am getting this error : I know it is a loader problem. Do I need to install any binaries? administrator@administrator-desktop:~/Desktop/libvirt/examples/domain-events/events-c$ gcc event-test.c -o event -lvirt /tmp/ccHd7ZUD.o: In function `main': event-test.c:(.text+0xac9): undefined reference to `virConnectRegisterCloseCallback' collect2: ld returned 1 exit status Thanks Avanti
