Why I failed to compile a sctp program in Linux?

Question

First I install sctp on Ubuntu 12.04
sudo apt-get install libsctp-dev lksctp-tools
Then in my .c file,I include :

#include < netinet/in.h >
#include < netinet/sctp.h >
#include < sys/socket.h >
#include < stdlib.h >
#include < unistd.h >

howerver,when I compiled with gcc,the result is:

 undefined reference to `sctp_recvmsg'
 undefined reference to `sctp_get_no_strms'
 undefined reference to `sctp_sendmsg'

What is wrong?

Show your compilation command, ans some part of your source code. — Basile Starynkevitch, Apr 21 '13 at 12:34
Show the `gcc` command you are using to compile your program. Remember that the order of arguments to `gcc` matters a lot. — Basile Starynkevitch, Apr 21 '13 at 12:55

If you really compile with gcc temp.c -o temp then you are not linking any libraries (except the default libc.6.so), and you need some additional argument to gcc ; perhaps try to compile with

 gcc -Wall -g temp.c -lsctp -o temp

Once your program is debugged with the help of the gdb debugger and you consider it to be bug-free, you may ask the compiler to optimize it using

 gcc -Wall -O2 temp.c -lsctp -o temp

The order of program arguments to gcc is important and significant.
