very important

Sir,
I m facing a problem in using libpcap in a C program on linux 7.2. I have 
libpcap-0.7.2 installed in the root directory. and have copied the folder in 
the include directory. but when I compile my program it gives the following 
error:

/tmp/ccSuKW14.o(.text+0x1ab):undefined reference to "pcap_lookupdev"

the same error comes on all the libpcap functions. I have also tried to 
install libpcap in the include folder and then include the file but it 
doesnt work even then.
What should i do. Should I have to do something extra to be able to use 
libpcap in my folder.
