ipv6 problem

["v.chitra" <vkchitra@xxxxxxxxxxxxxx>]

hye
i am working in drdl. i am creating socket library for IPv6 in 
Linux OS.
i did a sample program giving AF_INET6 to socket function.
but when i compiled the program, it is saying that Family not 
supported.
for compilation i gave the following command:

g++ -o server server.cpp

i want to know how to compile programs for IPv6. what are the 
linker options we have to give. since i month i am facing this 
problem.
reply as soon as possible.
thank you
bye
